TrakPower V-Balance Module
Thank you for purchasing the TrakPower V-BALANCE MODULE, a modern high performance,
software-driven, equalising, pass-through cell balancer system. The V-Balance system has been
designed with two main functions in mind: Firstly to maintain peak performance of Lithium Polymer
battery packs by equalising the charge-state of each cell within a pack. This process reduces the
possibility of each cell becoming exposed to damaging overcharge and undercharged states during
use and helps maintain useable charged-in capacity by balanced loading. Secondly the system has
been designed as a high-current charge-through safety device that can intercept and halt a wide
variety of product damage and safety scenarios that can be encountered during charging and bench-
discharging. While no substitute for responsible observation, the V-Balance system (in pass-through
operation) will halt overcharge resulting from incorrect charger settings, faulty or poorly calibrated
charger, faulty or damaged cells and severely out-of-balance packs. The V-Balance will assist
balanced discharging and in pass-through operation will also halt over-discharging of any cell.
The V-Balance has two main modes: Passive Balancing mode and Link Mode.
The V-Balance module has been designed in conjunction with TrakPower and FlightPower EVO
product types but may also be used successfully with other brands of 2s-6s Lithium Polymer battery
packs with the purchase of low-cost adapter cables.
FEATURES

Summary of Contents for TrakPower V-Balance

  • Page 1 While no substitute for responsible observation, the V-Balance system (in pass-through operation) will halt overcharge resulting from incorrect charger settings, faulty or poorly calibrated charger, faulty or damaged cells and severely out-of-balance packs. The V-Balance will assist balanced discharging and in pass-through operation will also halt over-discharging of any cell.
  • Page 2 If the pack is already balanced the V-Balance will flash all LEDs corresponding to cells in the pack 8 times slowly and go into sleep mode unless the Link Mode is activated first. If the pack is not fully balanced, one or more LEDs will flash indicating that balancing action is taking place and this will continue until the battery is balanced (unless in extreme cases a low voltage limit is detected first).
  • Page 3 V-Balancer as described before and the V-Balance will equalise the charge of your battery pack (as long as the pack is not over discharged). The V-Balance has a low voltage cut off of 3.0V per cell to prevent deep discharge. Your V-Balance unit also features a battery fuel gauge for checking the state of charge of the total pack and of individual cells.
  • Page 4 Safety Features and Specifications The V-Balance system adds an element of safety to the charging system and will prevent: Over-charging above 4.21V per cell (highest cell), over-discharging below 3.00V per cell (lowest cell).

    Over Discharge Protection Voltage 3.00V+-0.010V IMPORTANT. TrakPower V-Balance has been designed and manufactured to be an asset to maintenance and safety when handling Lithium Polymer batteries for RC use. It is not a substitute for responsible observation and good practice. Lithium Polymer batteries should be regarded as solid fuel and charge-safety regimes must anticipate the possibility of fire in the event of equipment failure (including failure of the V-Balance system) and mistakes made when using charging apparatus.
  • Page 6 Link Mode V-Balancer will then check for any cell below 3.0V, If any cell below 3.0V is found then 1st LED of battery fuel gauge will blink and V-Balance will go to sleep mode until reset/mode button is pressed. V-Balancer will check any cell above 4.21V, if any cell is above 4.21V the V-Balancer will try to bring down the cell voltage to below 4.21V (4.21V) by discharging that particular cell.
