1 INTRODUCTION 1-1 SCOPE There are various models of VMC Lite. While each model has unique input power requirements, all have the same volume and accept the same battery adapters. The adapters are also identical to those used with the BTC-70836 (PP-8481B/U). The VMC Lite is a state-of-the-art, high performance battery charger designed to be mounted to a vehicle. This allows batteries to be charged while the vehicle is moving or stopped. The charger can also be dismounted for shop usage. It provides fast reactivation of various rechargeable batteries. Depending on the adapters used, it is capable of sequentially charging up to eight batteries, one at a time, completely unattended. It can multi-charge up to eight batteries at once if the battery is cable of parallel charging (see asterisk in Table 1-4.1). This charger utilizes the same battery adapters, AC cable, and 24Vdc input cable as the PP-8481B/U. The VMC Lite contains mounting brackets and is designed to be mounted onto the wall or other fixture of a vehicle. The VMC Lite is simple to use by design. Without any user intervention, the VMC Lite typically charges fully depleted BB-2590 s or BB-390B s in less than 3 ½ hours. The charge time is substantially less for partially discharged batteries. Charge times vary based on battery type and the battery s state of charge. The Charger automatically identifies the specific battery type and provides the appropriate charge profile. Based on the current operating environment, the VMC Lite automatically customizes the charge profile to provide the quickest charge in a safe manner. The charge status for each of the batteries is conveyed to the user via easy-to-understand panel mounted LED indicators (amber CHARGE, green READY and red FAULT). The VMC Lite is universal by design. Depending on the specific model, it can be powered with universal AC mains, vehicle +12Vdc or vehicle +24Vdc. When operated with vehicle power, an Under-voltage Lockout Circuit prevents the Charger from excessively discharging the vehicle battery so there is always enough power to restart the vehicle. The VMC Lite is adaptive by design. It is microprocessor controlled and is presently programmed, with the appropriate battery adapter, to automatically charge over 25 different battery types as listed in the Table 1-4.1. It can be readily field reprogrammed via its USB software upgrade port. This allows it to charge a countless number of additional battery types and chemistries including: Nickel Metal Hydride, Nickel Cadmium, Lithium Ion, and Lithium Polymer. The battery charger components are housed in a durable aluminum case. The assembled unit is watertight when the cover is securely latched and the pressure equalization screw on the side of the case (near the bottom) is closed. The text on the control panel is reversible so the unit may be reverse-mounted for use in vehicles such as the Stryker. www.bren-tronics.com Page 4 of 46 VMC Lite VEHICLE MOUNTED CHARGER LITE Data presented in this document is subject to change without notice

1-5 CHARGE CYCLE DESCRIPTION Each of the battery types that are capable of being charged by the VMC Lite is connected to the charger via their respective battery adapter plate. Each adapter can independently charge one battery at a time. The appropriate battery adapter is installed into the adapter port and serves as the electrical interface between the batteries being charged and the charger circuits. The battery charger control circuits constantly monitor the following battery conditions during the charge cycle, as appropriate, to ensure that the battery is properly being charged: a. Temperature (T) b. Voltage (V) c. Current (I) d. Time (t) e. Voltage change ( V) f. Temperature rate of change ( T/ t) The charger operation during a typical charge sequence is automatic and the battery charge status is displayed to the user by the panel LED indicators as follows: a. Detection - The charger tries to detect a battery in an adapter. The CHARGE STATUS LED slowly blinks amber during this process. b. Pre-charge The charger brings the battery voltage up to a safe level before the rapid charge process begins. This step may take several minutes for a very discharged battery. The CHARGE STATUS LED rapidly blinks amber during this process. c. Fast Charge A timed fast charge cycle brings the battery to approximately 90% of full charge capacity. The CHARGE STATUS LED is lit steady amber during this process. d. Trickle / Top-off When fast charge is complete, the charger will top off of the battery to 100%. Each battery is charged for five minutes at a time (10 minutes for dual section batteries i.e. BB-390A/U, BB-390B/U, BB-2590/U, BB-557/U, BB-2557/U). For Lithium Ion and Lithium Polymer batteries the top-off cycle will stop after the battery is 100% charged. For all other types, the Trickle / Top-off cycle is repeated indefinitely to keep the battery at 100% charge. Leaving the battery on the charger will not harm the battery. The battery may be removed and used at this time. The CHARGE STATUS LED slowly blinks green during this process. e. Ready The fast charge cycle is complete. The Battery may be removed and used at this time. The CHARGE STATUS LED is lit steady green at this time. www.bren-tronics.com Page 11 of 46 VMC Lite VEHICLE MOUNTED CHARGER LITE Data presented in this document is subject to change without notice
NOTE The Battery may be removed and used at anytime during the charge cycle without damage to the charger or battery. If present, the state-of-charge indicator (SOC) will display the battery condition. NOTE After removing a battery from the charger, wait for the corresponding battery status LED s to turn off before installing a new battery. www.bren-tronics.com Page 12 of 46 VMC Lite VEHICLE MOUNTED CHARGER LITE Data presented in this document is subject to change without notice
1-6. SEQUENTIAL CHARGING CYCLE DESCRIPTION The VMC Lite can sequentially charge the supported batteries with the appropriate adapter. Using the Universal Adapter, the VMC Lite can automatically charge up to seven batteries in less than 12 Hours. Charge times will vary based on the battery type, state-of-charge and temperature. Other adapters can support a varying amount of batteries. The charging port can charge one battery at a time, except in the case of multi- charges the additional batteries that are waiting in queue. Sequencing to the other charging. Upon charge completion of the first battery, the charger sequentially positions is performed completely automatic and requires no intervention by the user. Figure 1-6.1 - VMC Lite with Universal Adapter During the sequencing process, the channel spends only as much time as is necessary to charge each battery to greater than 90% capacity. A partially charged battery will charge quicker than a totally discharged battery. It then sequences, in numerical order (Position 1, Position 2, Position 3 then back to Position 1, etc.) ), to the next battery in queue. As the channel sequences through the Positions and comes to a battery that has already been charged, it will attempt to Trickle or Top-off that battery (if necessary) for approximately 5 minutes (10 minutes for dual section batteries like the BB-390A/U U, BB-390B/U, BB-2590/U, BB-557/U, and BB-2557/U) and then continue onto the next Position. This means batteries added later may charge first, depending on their position on the charger. If certain batteries must be charged first, then this must be taken in to account. When the charger moves to a position it will charge or top off the battery at that position, as necessary. This allows batteries to be added or removed at anytime. The charger automatically keeps track of the current state of each Position. www.bren-tronics.com Page 13 of 46 VMCC Lite VEHICLE MOUNTED CHARGER LITE Dataa presented in this document is subject to change without notice
1-7. MULTI-CHARGING CYCLE DESCRIPTION Along with sequential charging, the VMC Lite can also charge up to 8 batteries at once. The charger will automatically identify batteries than can be multi-charged; no special action is required by the user. This feature charges the batteries in parallel. For example, four standard MBITR batteries can be charged within 4 hours. Significant time savings will be noticed for smaller groups of batteries. Multi-Charging does not require any special setup. The Multi-Charging process works as follows. The VMC Lite has one high power charging channel. The unique characteristics of Lithium Ion batteries allow the charger to charge certain batteries in parallel. This allows the channel to use maximum power for a longer time. This can produce a large savings in time, charging four MBITR batteries simultaneously takes four hours compared to three hours for just one. The charging sequence is similar to normal battery charging with the exception that if a multi-chargeable battery is found the charger will pre-qualify it (status indicators flashing amber) and look for more. Incompatible batteries will be skipped, until later. When the charger can find no more batteries it will start the rapid charge phase. The status indicators will now be solid amber. As each battery finishes, the status indicators will turn green one at a time as each battery is completed. A battery with a green indicator can be removed and used as a normally charged battery. After the charger has completed the group, it will continue charging other single or grouped batteries as it finds them. To minimize charge time with Multi-Charging, a few rules apply. While the status indicators are yellow, removing a charging battery will restart the entire group. This is normal. If batteries are added after the LEDs have turned amber, they will not be added to the group. If the LEDs are still flashing amber then batteries can still be added to the group. This is true even if the charger has passed the position, it will go back until it has collected all the batteries to be charged. If there is a large quantity of batteries to be charged, grouping the batteries will save charge time. Batteries that have similar SOC indications should be grouped together. This prevents the almost fully charged batteries from having to wait for a fully discharged one to catch up. Some batteries are available in different capacities, but can still use the same adapters. Remember that multi- charging a group of batteries is always faster than charging them one at a time. (Note: Falcon II and Falcon III batteries, although similar, will not be grouped together for multi-charging.) www.bren-tronics.com Page 14 of 46 VMC Lite VEHICLE MOUNTED CHARGER LITE Data presented in this document is subject to change without notice

NOTE Make sure that the Vent / Drain screw is fully closed. www.bren-tronics.com Page 30 of 46 VMCC Lite VEHICLE MOUNTED CHARGER LITE Dataa presented in this document is subject to change without notice
2-3 PRELIMINARY SETUP PROCEDURES Step 1. VEHICLE MOUNT: Mount the Charger into the vehicle. Ensure it is mounted securely (See Para 2-2), and the cover has room to open at least 90 degrees. Ensure the charger has free airflow around it. If airflow is restricted, the charger may charge batteries more slowly, or overheat and not charge at all. Connect the appropriate DC cable to a 20 AMP DC source in the Vehicle. Connect the DC cable securely to the charger. Place the Dust Cap over the unused connector if using the -3. SHOP USE: Place the unit on the work surface. Ensure the charger has free airflow around it. Connect the AC cable securely to the charger. Connect the other end of the AC cable to a standard AC outlet (AC power not applicable for -1). Step 2. Step 3. Step 4. Step 5. Step 6. Unfasten the two cover latches and open cover. If necessary, loosen the manual pressure equalization screw on the side of the case (near the input power connector) in a counterclockwise direction about two full turns. Make sure that the screw is re-tightened once equalization is complete. Install appropriate battery adapter into the adapter port for the battery types to be charged. Install the adapter by locating the base of the adapter over the two polarized 27 pin female connectors on the charger panel at Port A and pressing down firmly on the adapter s finger grip handles until the polarized male connectors on the adapter mates with the female polarized 27 pin connector on the charger s panel. Note the alignment of the pins. The multi-pin connectors on the adapter are polarized and can only plug in one way onto the multi-pin connector on the charger s panel. Do not force it. Be sure that the battery adapter and battery connections are fully seated. All battery adapters are interchangeable, only the battery connections are different. Tighten the retaining screw in the center of the adapter (Do Not Over-tighten). Set the power switch to ON position. Observe that the POWER ON LED lights, the fan operates, and all the LED status indicators blink in order (amber, green, then red) briefly when power is first applied. Observe, after a short delay, the amber CHARGE STATUS LED s blink for several seconds at position 1 of the installed adapter. This shows battery charger circuits are initialized to the selected battery adapter and are ready to accept a battery (or batteries) for charging. If all of the Indicators for a channel light red with no batteries installed, the adapter is not be recognized or is damaged. Ensure it is seated correctly. Verify that the charger software revision supports the adapter. www.bren-tronics.com Page 31 of 46 VMC Lite VEHICLE MOUNTED CHARGER LITE Data presented in this document is subject to change without notice
2-4 CHARGING BATTERIES Step 1. Step 2. Step 3. With the adapter installed, insert the first battery to be charged in the proper Port-A battery location. Ensure the battery is fully seated into the adapter. Observe that CHARGE STATUS LED for the corresponding location starts rapidly blinking amber. If the CHARGE STATUS LED turns red, the battery or adapter may be defective. Check by removing battery and adapter. Then reinstall adapter and battery. If the CHARGE STATUS LED again lights red, go to the Trouble Shooting section of this Guide. Install the rest of the batteries. The indicators for these batteries will not light until the charger has finished the batteries in the preceding positions. After fast charging is complete, the CHARGE STATUS LED will light green. After the charger cycles through the batteries, it will top-off batteries that have completed fast charge. The battery is slow-charged to full capacity, as indicated by the CHARGE STATUS LED blinking green. The battery is charged for five minutes at a time (10 minutes for dual section batteries) then the charger will move on to the next battery. For Lithium type batteries, the cycle will stop after the battery is 100% charged. For other types the cycle is repeated indefinitely to keep the battery at 100% charge. As long as the CHARGE STATUS LED is lit green (blinking or solid) the battery may be removed and returned to service and another battery may be installed for charging, in its place. NOTE BB-390A/U and BB-390B/U batteries include two independent 12-volt sections. A relay "clicking" may be heard from the battery adapter when battery sections are switched. Other types of adapters may also contain relays and click intermittently during normal operation. NOTE Battery charger power may be left ON while batteries and/or adapters are removed or replaced. Batteries may be left in the charger for long periods of time without damaging the batteries or charger. CAUTION To avoid damage to the adapter or VMC Lite panel connectors, always remove the adapter by first loosening the retaining screw. Then grasping the Tee finger-grips firmly with both hands. Pull the adapter toward you, not straight up. You may need to wiggle the adapter back and forth to remove it. www.bren-tronics.com Page 32 of 46 VMC Lite VEHICLE MOUNTED CHARGER LITE Data presented in this document is subject to change without notice

Mark for future review, if a continuing problem at this location: change adapter. www.bren-tronics.com Page 35 of 46 VMC Lite VEHICLE MOUNTED CHARGER LITE Data presented in this document is subject to change without notice
2-10 OPERATION IN EXTREME ENVIRONMENTAL CONDITIONS Observe these precautions when the VMC Lite is operated in areas where severe climatic conditions may exist. The charger will not charge batteries if it is outside the allowable temperature range. Batteries outside the operating range will charge slowly, or not at all. a. Operation in Arctic Climates. The battery charger is designed to function in temperatures extremes as low as -4 F (-20 C). The following precautions should be observed: (1) Handle equipment carefully. The plastic components may become more brittle. (2) Keep equipment clean and dry. (3) Prevent ice from forming in the VMC Lite and on the batteries. Ice formations may prevent proper electrical connections. Melting ice may cause water to enter the charger. Keep the cover closed and latched except when installing or removing batteries. Dry batteries before placing them in the charger. b. Operation in Desert Climates. The charger is designed to operate in temperature extremes as high as 122 F (50 C) and the dryness associated with a desert environment. Sand and dust accumulation on and in the charger may cause poor electrical connections and reduce the cooling effectiveness of the charger. Follow proper cleaning and maintenance guidelines to assure proper operation. Keep the cover closed and latched, except when installing or removing batteries. Be sure that cover is fully latched and pressure relief valve is fully closed (in a clockwise direction). As the internal charger temperature rises, battery charging time will increase. c. Operation in Salt Spray. Keep equipment clean and dry at all times and immediately wipe salt spray from exposed surfaces, cables and connectors. Wipe off salt and dry batteries before placing them in the charger. Keep the cover closed and latched, except when installing or removing batteries. Be sure that cover is fully latched and pressure relief valve is fully closed (in a clockwise direction). NOTE Battery charge acceptance varies with ambient temperature conditions. At temperatures lower than +32 F (0 C) or higher than +104 F (+40 C) it may be necessary to initiate two complete charging cycles to secure a fully charged battery. It is recommended that the VMC Lite be installed for DC operation to reduce the heating effects caused by the AC power conversion. In arctic conditions however, the extra warmth resulting from AC operation may prove to be a better choice by improving the battery charge acceptance. Bottom line bring along both the AC and DC cables so you ll be ready if your operational environment changes! www.bren-tronics.com Page 36 of 46 VMC Lite VEHICLE MOUNTED CHARGER LITE Data presented in this document is subject to change without notice
2-11 REMOVING THE CHARGER FROM THE VEHICLE a. Set the POWER switch to OFF. b. Remove any installed batteries. c. Close the charger lid and secure the cover latches. d. Disconnect the power input cable and replace the connector cover. e. Remove the mounting bolts. f. Remove the charger for the vehicle. g. Close pressure equalization valve on the side of the charger by turning fully clockwise. h. Save the mounting bolts for later installation by reinstalling them in the dismounted charger mounting holes 2-12 BATTERY STATE-OF-CHARGE DISPLAYS Batteries equipped with state-of-charge (SOC) displays indicate battery charge status on a five-segment LCD bar graph readout. The number of LCD segments activated corresponds to the battery state-of-charge as follows: Segments State-of-Charge 0 0% (fully discharged) 1 1 to 20% 2 21 to 40% 3 41 to 60% 4 61 to 80% 5 81 to 100% (fully charged) NOTE The BB-390A/U, BB-390B/U, BB-2590/U, BB-2557/U and some other batteries have two SOC indicators. Each SOC indicator provides state-of-charge indication for each of the two 12V sections. Both SOC s must display 100% for the battery to be fully charged. www.bren-tronics.com Page 37 of 46 VMC Lite VEHICLE MOUNTED CHARGER LITE Data presented in this document is subject to change without notice
2-13 BATTERY CAPACITY RETENTION As shown in the adjoining graph, fully charged batteries that are stored lose a portion of their charge due to battery chemistry. This is normal and should not be interpreted as battery failure. Storage at higher temperatures increases capacity losses while storage at lower temperature decreases capacity losses. The graph shows that Nickel based batteries like the BB-390 lose over 30% charge/month (1% /day) on the shelf waiting to be used. The BB-2590 (a Li-Ion based battery) only loses less than 10% a month on the shelf. 2-14 BATTERY STORAGE Nickel based batteries may require 1 or more charge / discharge cycles after long storage. They may not charge fully on the first charge cycle. Repeat the charge if necessary. If the battery does not fully charge after 3 cycles it may no longer be serviceable. Lithium based batteries must be charged yearly if held in storage. Long term storage of fully discharged Lithium based batteries can permanently damage the battery. Lithium Ion batteries do not have a memory effect; hence they do not require charge / discharge cycling after storage. If the battery does not charge (no SOC Bars), place it back on the charge for an additional charge cycle. If the battery does not fully charge it may no longer be serviceable. www.bren-tronics.com Page 38 of 46 VMC Lite VEHICLE MOUNTED CHARGER LITE Data presented in this document is subject to change without notice
