5 SAFE START MENU SYSTEM AND SOFTWARE FEATURES Although different from the original implementation of Safe Start technology first seen in the Primal charger, the Ascend features the same logic. The Safe Start menu system is different from any charger you may have used before and thus designed to help you, the user consciously select the correct charging mode for your batteries to protect both yourself and your equipment, while remaining easy to operate and understand what you are doing with the charger. Safe Start Logic: When the charger is powered on you will be greeted and automatically routed to the area of the software where you can select your desired function. The default start screen is always the LiFe charge mode. This default provides the simplest menu system that also incorporates the highest level of safety seen in today s chargers. Here s why: Due to the charging algorithm used, charging in LiFe charge mode is the safest option of those offered by the Ascend charger as it charges to the lowest termination voltage. Many batteries will fall out of the voltage limits of that mode if you accidentally try to charge a battery not designed for it. The LiFe mode is a balance only charging mode that requires you to insert a balance plug into one of the ports (or aftermarket universal adapter board). Since NiXX type batteries do not have a balance plug and thus cannot be connected, as part of the Safe Start system the charger will not charge these batteries in LiFe mode. If a LiPo battery is by chance at a low enough voltage to be accepted by the charge mode, it will only receive a partial charge, still a safe result from the opposite alternative Charge Mode (Charge Rate Calculation Mode): The Ascend is equipped with two charging modes relative to each battery primary chemistry which allows setting of the charge rate based on either the capacity of the battery being charged or a user input value (the last value used is remembered for each charge mode for your convenience). We recommend charging by capacity charge mode as it offers the safest operating conditions. Here s a description of both options that are available under the Options menu of your charger. This option can be set independently of chemistry (LiXX/NiXX). Capacity Mode: After selecting a charge mode (LiFe, Li-Ion, LiPo, NiMH/NiCd) from the main menu, you are presented with the screen to set the battery capacity. Enter the mah value printed on your battery pack. Minimum value: 100mAh Maximum value: 9900mAh After entering the battery capacity the charger will calculate the maximum allowable charge current as 1C but. The following confirmation screen will display the calculated maximum allowable charge rate. Using common sense calculation (like having an idea of how much change you should get back from a teller after a cash transaction) make sure this value is not higher than expected. If it is, go back and double check the entered value for mah. When the charger measures the capacity increase in the battery at the entered value, the charge cycle will automatically stop to prevent over charging. Current Mode: After selecting a charge mode (LiFe, Li-Ion, LiPo, NiMH/NiCd) from the main menu, you are presented with the screen to set the charge current. NOTE: See the index in this Owner s guide for a guide to calculate the charge current based on a battery s charge C rating Minimum value: 0.1A Maximum value: 6.0A Note: The charger will always try to achieve the desired paremeters that you have entered for charging while taking into account the attached battery and input power source. However to keep the charger in safe operating limits the maximum charge current may be reduced as needed. A standard 120min safety time is used in current mode. Some high capacity batteries or batteries charged at less than 1C may take longer than this to complete the charge. Use your discretion to determine if the battery needs to be charged again before use. WARNING: Always allow batteries to cool completely before re/charging. CAUTION: It should always be noted that safety timers of any type do not alone prevent over charging, they are meant to be useful in the most typical charging conditions however they can all be circumvented. For this reason its is always recommended to never leave your batteries unattended while charging and to monitor their condition periodically. Disconnect input power and battery immediately if the battery, connector, or charger becomes hot or changes form (swells, bulges, indents, etc.) during use. Simple Capable Safe 5

6 SAFE START MENU SYSTEM AND SOFTWARE FEATURES CONTINUED Confirm the Settings: After deciding and setting either the charge current or battery capacity and pressing enter, you are asked to confirm the settings that you have just entered. It is most important to confirm the following items: Battery Type/Chemistry is accurate Charge rate does not exceed 1C (unless done intentionally, see Index at the back of this manual for charge rate calculations) Starting a Charge: Once you have visually confirmed the settings for charging your battery, press and hold the Enter button for 3 seconds. The charger will display a message as it checks for any errors in the connections, battery voltage etc., you may then release the button and the charge will start if all the checks are succesful and determined OK. Charge Data: Your charger will now display the charge status and current charge data including the Time, Voltage, Charge Current, and mah (in). You will also notice a very unique feature displayed in the upper left hand corner of the screen. Here are the letters you will see and their corresponding definitions. CC: Constant Current mode used for the initial charge phase when charging LiPo/Fe batteries and the entire charge cycle for NiXX batteries CV: Constant Voltage mode used for the final charge phase when charging LiPo/Fe batteries. You will see this displayed for approximately the last 20% of the charge cycle indicating the battery is approximately 80% charged DV: Delta-Peak mode is used to detect the voltage drop during the charge cycle for NiXX type batteries. This setting is used to monitor the voltage drop of the battery pack and it is what determines when the battery is fully charged. The D-Peak setting is adjustable for both NiMH and NiCD separately from 5-20mV in the Options menu. We recommend only changing these values if your an advanced user; otherwise leaving the default settings for each battery type as they come from the factory will give you good and consistent power form your batteries Advanced Charge Data: During any charge cycle, you can press the Enter button to view more information about the current charge. For Li/XX batteries, you will be shown a table of the individual cell voltages. For NiXX batteries, you will be shown the current Peak Voltage and DV value as it is monitored in real time. Charge Summary: Upon charge completion the charger will sound an audible alert indicating the charge cycle is done. Pressing the Enter button will silence the alert. At this time you can disconnect the battery from the charger, but do not press the Back/Cancel button yet! There s more information waiting for you. By pressing the Up/Down buttons you can scroll through the charge summary screens displaying more vital information about your battery s charge cycle. Here you will find: Done T: Shows the amount of time since the battery charge has been completed Final V: Shows the final voltage that the battery peaked at. It is common for the battery voltage to fluctuate after a charge is complete, this just shows what the charger read as the charge completed Peak V: Shows the highest voltage of the battery that was read during the charge cycle mah (in): Shows the approximate capacity that was charged back into the battery Charge T: Shows the length of time the battery was charging Pressing the Back/Cancel button at anytime will return you to the beginning of the Menu system at LiFe Charge mode for safety reasons described earlier in this manual. Note this will STOP the charge cycle if one is in process. Believe it or not, your Ascend charger does more than just charge batteries. If you continue past the charge functions in the beginning of the menu you will see a Tools and Options menu that provide some advanced features never before seen in a product like this. Tools: There are times when knowing the voltage of your battery is handy, either when checking the charge state or just to see if there is a bad connection somewhere. For this reason we have included two different Volt meters for you to use. They are described below. Volt Meter: Displays both the charger input voltage (DC only) and the output voltage. This feature is helpful if you are using your real car 12V battery as a power source so that you can monitor the input voltage and not accidentally drain your real car battery. While the most useful case for monitoring the input voltage, it is not the only since you can also use it to adjust the output of your power supply and know where to stop so that you don t exceed the input voltage limit of 15V. This is also useful for checking the voltage of a standard NiXX battery pack. Balance Meter: Displays the overall voltage and the individual cell voltages for a LiXX battery so that you can see the state of the balance of your battery. Given that the Ascend is a balance charger, if the cells are a little off you shouldn t need to worry as they will be balanced within close tolerance on their next charge. NOTE: the voltages displayed here are more accurate than those displayed on the Volt Meter menu so you will notice a slight discrepancy if you are comparing numbers 6 MULTI-CHEMISTRY AC/DC PEAK DETECTION BALANCE CHARGER

7 SAFE START MENU SYSTEM AND SOFTWARE FEATURES CONTINUED... Options: The Options menu contain various settings for your charger and one very useful feature for maintaining the health of your LiPo batteries, a LiPo Storage charge mode. Here s a list of what you ll find under the Options menu LiPo Storage: This mode is very similar to the standard LiPo storage charge mode however you can only charge using the capacity mode to determine the charge rate, regardless of the default setting for the normal LiPo charge mode. This is done for more accurate calculations and to help get your battery in the optimal state for long term storage (max 6 months) LiPo storage mode will charge your batteries to approximately 3.85V per cell (approx 80% of full charge) You must start this storage charge cycle with a battery that is under 7.6V for the battery to charge properly since the Ascend is not equipped with a high current discharger capable of reducing the voltage of a fully charged battery pack LiXX Charge Mode: Gives you the option of calculating the charge rate based on either capacity or current for LiXX based batteries. See the Index of this manual for more details on charge rate calculation NiMH/Cd Charge Mode: Gives you the option of calculating the charge rate based on either capacity or current for NiXX based batteries. See the Index of this manual for more details on charge rate calculation Default Values: Here you are able to select the delta peak voltage value for NiMH and NiCd batteries. This value is set to 8mV by defaul but it is adjustable between 1-20mV to suit your needs. Audio Tones: This setting allows you to be able to turn the audio alarms for button presses or charge complete alerts on or off Input Power: Your charger is equipped to accept input power from either a V AC wall plug or from a 12-15V DC power supply. A common 12V power supply used is a typical full size lead acid battery from an automobile. Do not connect both power inputs at the same time. Reminder: We want to remind you that just because the Ascend charger has advanced features it doesn t mean you have to use them. We set out with the intent of making this charger easy to use and understand so that you are not kept in the dark or forced to decode cryptic words on a tiny screen. We also wanted to improve on the safety of using a charger with any of today s most common battery types, this seems to be something that many people have forgotten about. When technology changes, it is critical to update the users with the information and tools required to gain the maximum enjoyment out of using the product. We feel we have raised the bar in this area and we hope you do to. If you still feel that you want to stick to the basics, we happily encourage you to do so and learn at your own pace when the time is right. Never hesitate to ask questions and seek advice where you find there is need. Lets get charging: Now that you are familiar with the charger, its features, and general precautions of what not to do and some of what to do, we should get started charging your first battery. Just a reminder...set some time aside so you DON T have to walk away and STOP THE CHARGER, MID CHARGE since you should NEVER LEAVE THE CHARGER UNATTENDED WHILE CHARGING. Finally, confirm the battery chemistry type, capacity, voltage and cell count of the battery you will charge and ensure all connector plugs are compatible. 1. Plug the charger into a properly grounded AC wall plug or DC power source. 2. Plug the battery into the charger and place the battery on/in a non-flammable surface/container and away from any flammable objects. 3. Read and follow the following charge instructions for your battery chemistry type (from battery manufacturer too). 4. Unplug the battery from the charger when the charge is complete. 5. Remove charger from wall plug when not in use a. NOTE: Only use batteries with labels that are legible and clearly state the capacity, cell count (or voltage), and chemistry type as either NiCd, NiMH, LiPo, Li-Ion, or LiFe (A123). THIS PART IS REALLY IMPORTANT, PLEASE READ AND UNDERSTAND IT... WARNING: The Radient Ascend charger has the capability of charging both LiFe/Li-Ion/LiPo (LiXX) and NiCd/NiMH (NiXX) batteries which require significantly different charging modes. It is extremely important to choose the correct charging mode when charging your batteries. Choosing the wrong charging mode can cause fire or explosion. Be sure to properly identify the battery chemistry, voltage and capacity of every pack before attempting to charge it to ensure the correct settings. Some LiPo battery packs are designed to look like NiXX battery packs. One indication of a LiPo battery is the presence of a balance plug either exiting the battery with small wires and small plug on the end or a small female plug embedded into the end of the battery pack. If you are unsure of the battery type you are attempting to charge; please consult your local hobby dealer for assistance. To help ensure the correct charging mode is used when charging your batteries, the charger is equipped with Safe Start technology. Safe Start is a start sequence technology used to deter the use of the incorrect charging mode for batteries of different chemistry. When battery packs are connected properly per chemistry the system is very robust; however if some batteries are improperly connected it is possible to charge LiPo batteries in NiXX mode, exactly what you should NEVER do, so caution is always required when operating the charger. Safe Start is used by requiring the simultaneous pressing of both the Safe Start button and the appropriate charge mode button for 3 seconds to begin the charge cycle. Simple Capable Safe 7

8 CHARGING A LiPo/Li-Ion/LiFe BATTERY The Radient Ascend charger supports charging of LiFe, Li-Ion and LiPo batteries, however since the process of charging these batteries is very similar, we will walk through the steps of charging a common LiPo battery which can then be applied to the charging of a LiFe or Li-Ion with the substitution of functions (and voltages displayed below) being used on the charger. Both of these batteries charge using Constant-Current Constant- Voltage (CC-CV) charge mode for 2s-3s cell configurations with available charge current range from Amps. NOTE: Your charger is equipped with both a capacity based and time based safety shut-off timer set to 120min. Charging of batteries with capacity higher than 5000mAh, or charging batteries at less than 1C may require a greater charge time and thus require more than one charge cycle to achieve full charge. It is always recommended to allow your battery to cool to room temperature before charging either the first or second time. To charge a LiPo battery in CC-CV charge mode, perform the following steps: 1. Connect your LiPo battery s balance plug connector to either the JST-XH (2s or 3s) balance port built into the charger or into a connected external balance adapter board (RDNA0003 for example). a. NOTE: Charging of LiPo batteries in LiPo mode without connecting the balance connector is not supported As an added feature to our Safe Start technology, if a balance plug is detected by the charger, use of the NiMH or NiCd charge modes are disabled and cannot be circumvented. 2. Connect the main charging leads to your battery. a. NOTE: it is critical that the battery always be connected with the correct polarity, Negative (-) = Black, and Positive (+) = Red. Only connect Like color and symbol together. 3. Use the Up/Down scroll buttons to select the LiPo Charge function form the LCD menu and press Enter. a. WARNING: Selecting the appropriate charge mode is critical to the safe charging of your batteries. Using a charge mode other for a battery type other than specified may lead to fire or explosion. Always read your labels carefully to ensure you have the correct information about your battery for setting your charger. i. Note: Although you may select charge currents up to 6A, the maximum final charge current may be reduced as needed to keep the charger operating within safe limits. Typically this occurs when charging a 3s LiPo at 6A. 01). Example: A 3s LiPo may start to charge at 6A but as the voltage of the battery increases the charge current will reduce to approximately 4A. ii. Utilizing this method of charge current control enables the charger to always try to charge your battery as close as possible to the setting you specify, while keeping the system within safe operating limits. 4. By default your charger comes in Capacity mode for setting the charge rate. a. Locate the capacity rating on your battery pack and use the Up/Down scroll buttons to select the capacity value closest to (but not greater than) the number listed on your battery pack and press Enter. i. To achieve the safest operating conditions and longest life from your batteries it is recommended to charge your batteries at no more than 1C. See the Index at the back of this manual for charge rate calculations. 5. The charger will now calculate the maximum appropriate charge rate for the information you have entered and ask you to confirm the calculation of charge rate and battery type is as you expect. a. NOTE: The charger will calculate the maximum based on the battery voltage, input power source and number of cells detected. b. If you notice an error on the confirmation screen, you can press the Back/Cancel button to go back and correct the problem. 6. When the settings have been verified as correct, press and hold the Enter button for 3 seconds to begin the charge cycle. a. The charger will perform an error checking process and once all is confirmed OK, the charge will begin. You can now monitor the charge status on the LCD screen and notice CC in the upper left hand corner of the screen indicating the charger is in Constant Current mode. Press Enter for more charge information. 7. Near the end of charge completion the LCD screen will display CV indicating it has switched to Constant Voltage mode, the battery is typically 80% charged at this point. 8. When the charge is complete, the audio alarm will sound (Press Enter to silence the alarm) and the LCD screen will display Charge Complete and present you with the charge summary data. Use the Up/Down scroll buttons to view the charge summary. 9. Press the Back/Cancel button to return to the beginning of the menu or STOP the charge at any time. 8 MULTI-CHEMISTRY AC/DC PEAK DETECTION BALANCE CHARGER

9 CHARGING A NiCD OR NiMH (NiXX) BATTERY The Radient Ascend charger supports charging of NiMH and NiCd batteries, however since the process of charging these batteries is very similar, we will walk through the steps of charging a common NiMH battery which can then be applied to the charging of a NiCd with the substitution of functions being used on the charger. Both of these batteries are charged using a Constant Current Delta Peak (CC-DV) charge mode for 1-8 cell series configurations and adjustable Delta Peak values for each type with available charge current range from Amps. NOTE: Your charger is equipped with both a capacity based and time based safety shut-off timer set to 120min. Charging of batteries with capacity higher than 5000mAh, or charging batteries at less than 1C may require a greater charge time and thus require more than one charge cycle to achieve full charge. It is always recommended to allow your battery to cool to room temperature before charging either the first or second time. To charge a NiXX battery in Delta-Peak charge mode, perform the following steps: WARNING: Ensure your battery is truly a NiCD or NiMH battery. Some LiPo battery packs are designed to look like NiXX battery packs. If you are unsure of the battery type you are attempting to charge; please consult your local hobby dealer for assistance. NOTE: As an added feature to our Safe Start technology, if a balance plug is not detected by the charger, use of the LiPo or LiFe charge modes are disabled. By the same logic, if a balance plug is detected the use of NiMH and NiCd charge modes are disabled. This cannot be circumvented. 1. Connect the main charging leads to your battery. a. NOTE: it is critical that the battery always be connected with the correct polarity, Negative (-) = Black, and Positive (+) = Red. Only connect Like color and symbol together, any other form of connection may cause fire or explosion. 2. Use the Up/Down scroll buttons to select the NiMH Charge function form the LCD menu and press Enter. a. WARNING: Selecting the appropriate charge mode is critical to the safe charging of your batteries. Using a charge mode other for a battery type other than specified may lead to fire or explosion. Always read your labels carefully to ensure you have the correct information about your battery for setting your charger. i. Note: Although you may select charge currents up to 6A, the maximum final charge current may be reduced as needed to keep the charger operating within safe limits. Typically this occurs when charging a 8 cell NiXX at 6A. 01). Exp: A 8 cell NiMH may start to charge at 6A but as the voltage of the battery increases the charge current will reduce to approximately 4A. ii. Utilizing this method of charge current control enables the charger to always try to charge your battery as close as possible to the setting you specify, while keeping the system within safe operating limits. 3. By default your charger comes in Capacity mode for setting the charge rate. a. Locate the capacity rating on your battery pack and use the Up/Down scroll buttons to select the capacity value closest to (but not greater than) the number listed on your battery pack and press Enter. i.

12 INDEX Understanding C Ratings: Many battery manufacturers do not list the definition of or explain the purpose of C ratings and how to use that information. For LiPo batteries there is typically listed both a C rating for charging and discharging of the batteries. You must use caution that you calculate your charge rate based on the charge C rating and not the discharge C rating. Charge Rate Calculation The charge C rating of a battery refers to a ratio between the battery s capacity and the maximum safe charge current as determined by each manufacturer for each battery. This value is typically listed in the lower ranges between 1C-5C. It signifies the maximum current the battery should be charged at in a multiple of the capacity of the battery cells (on a per cell basis, not per pack basis) For example: if a battery cell is 2000mAh and the charge C rating is listed at 2C, the maximum charge current that should be used with this battery is equal to 2000 x 2 = 4000mA = 4.0A NOTE: 1000mAh = 1Ah. For simplified annotation, although charge rates are actually units of Ah, we refer to them as A only. Thus 1Ah = 1A The Ascend charger increments in values of 100mAh from 200mAh up to 9900mAh, if the calculated maximum charge rate is a decimal value (4.4) it is highly recommended to round this value down to the nearest whole number and use that as the maximum charge rate, but not necessarily the best charge rate option If the calculated charge rate is over the maximum capability for this charger, you can simply use the maximum allowed Radient RC recommends charging at 1C for the maximum cycle life of your batteries Always check the instructions provided with your batteries for proper charge and care. Those instructions should over-ride these since they pertain to the particular battery that you have and this is a general statement Discharge Rate Calculation The discharge C rating of a battery refers to a ratio between the battery s capacity and the maximum safe discharge current as determined by each manufacturer for each battery This value is typically listed in the higher range from 15C upwards. It signifies the maximum current the battery should be discharged at in a multiple of the capacity of the battery cells (on a per cell basis, not per pack basis) For example: if a battery cell is 2000mAh and the discharge C rating is listed at 30C, the maximum discharge charge current that should be used with this battery is equal to 2000 x 30 = 60000mA = 60A. This means you can continuously discharge this battery at a rate of 60A per hour without damage Since the Ascend charger does not discharge, this information is only for reference in helping you understand the terminology of the battery industry Termination Voltages (Peak Detection): LiFe/Ion/Po Batteries: The peak detection of a LiPo, Li-Ion, or LiFe battery works by increasing the voltage of the battery pack to a specified range. The goal of the charger is to increase the voltage of the battery into this range while injecting the most mah into the battery as possible. The charge cycle terminates when this value is reached. The nominal voltage of a LiPo battery cell is listed at 3.7V The Ascend charger will terminate the charge of a LiPo battery pack when it measures a voltage of V per cell. For a 2s 7.4 nominal voltage battery pack, the termination voltage would be 2 x 4.2 = 8.4V The nominal voltage of a LiFe battery cell is listed at 3.3V The Ascend charger will terminate the charge of a LiFe battery pack when it measures a voltage of V per cell For a 2s 6.6 nominal voltage battery pack, the termination voltage would be 2 x 3.6 = 7.2V The nominal voltage of a Li-Ion battery cell is listed at 3.6V The Ascend charger will terminate the charge of a Li-Ion battery pack when it measures a voltage of V per cell For a 2s 7.2 nominal voltage battery pack, the termination voltage would be 2 x 4.1 = 8.2V NiXX Batteries The nominal voltage of a NiXX battery cell is listed at 1.2V The Delta Peak (DV) value can be adjusted in the Options menu in the range of 1-20mV (default and recommended 8mV). Setting a lower D-Peak value will terminate the charge sooner, keep the battery temperature down, and typically extend the life of the batteries. We recommend starting with the default settings and make small changes as necessary. Setting a higher D-Peak value will terminate the charge later, create more heat, produce slightly more power, but typically reduce the life of the batteries. We recommend starting with the default settings and make small changes as necessary. Some older batteries may require a higher D-Peak value to charge successfully. The Ascend charger will terminate the charge of a NiXX battery pack when it measures a maximum voltage of the battery pack in a specified range and then also measures a drop in that voltage of the set D-Peak value found in the Options. The maximum voltage a battery pack reaches changes during the life of the battery (increasing with age). The characteristic behavior of the voltage drop remains the same however thus allowing the charger to continue to detect a peak voltage (maximum voltage - [D-Peak]mV) regardless of age. 12 MULTI-CHEMISTRY AC/DC PEAK DETECTION BALANCE CHARGER

13 INDEX CONTINUED Power rating (Watt-hour): Some products state a recommended Watt hour rating for a battery to be used with that product. The Watt hours can be approximately calculated knowing the battery capacity and the voltage For Example: if a battery is 2000mAh and the voltage is 8.4V the Watt Hours (Wh) is equal to 2000 x 8.4 = 16,800mWh = 16.8Wh Recommended Discharge Voltage Cut-offs: For maximum cycle life and safety, LiPo batteries should never be discharged below 3.3V per cell when discharged at a rate of 1-4C. For this reason, many electronic speed controllers have a special LiPo Mode which activates a cut-off of power when the ESC measures the battery voltage in a dangerous range For maximum cycle life and safety, NiXX batteries should never be discharged below 0.9V per cell when discharged at a rate of 1-4C. The use of an ESC low voltage cut-off mode is not necessary with NiXX batteries Storage Voltages: Although the Ascend charger does not offer discharge capabilities it is important to understand this information about your batteries since it is critical to both the safety of the battery and the cycle life. Always consult the battery manufacturer s documentation for storage information specific to that battery WARNING: You should NEVER store LiPo batteries at full charge for more than a few hours at most (and they should be stored at temps of degrees Fahrenheit whenever possible to help prevent swelling and/or loss of performance/capacity) LiPo batteries should be charged (or discharged depending on their state prior to storage) to approximately 50% of their rated capacity (approximately 3.85V per cell). The storage time at this voltage should not exceed 6 months and a use cycle and return to storage mode is recommended every 3 months The storage voltage of NiXX batteries is not as critical as LiPo but they should be stored in cool conditions and at a low cell voltage to prevent memory buildup and loss of capacity and performance NOTES Simple Capable Safe 13
