RE: i need a lipo balancer
Plug your 2 - 5 cell lithium battery pack into the balancer (using the supplied adapters for 2, 3, and 4 cell packs) and the unit immediately detects cell imbalance and starts a low-current (300ma) discharge of cells with higher voltages until they are within .01V of cells with lower voltages. LEDs on the unit flash to indicate which cells are out-of-balance and being discharged. When the LEDs stop flashing, the pack has been balanced.
The unit will also balance while charging and protect your cells from overcharge. Follow the above procedure, but then plug the balancer into your charger and begin the charge cycle. The unit will balance the cells as the pack is charged. If any cell becomes overcharged (reaching 4.30V), the unit will automatically terminate the charging, but continue to balance the pack. When the balancing is complete, simply charge the pack at a low current setting (0.5 amps or less) to recondition the battery.
