With the development of electric technology, we have a new design of easy compact balance charger for 2 and 3 cells LiPo battery fast charging with wide AC input. A internal 100-240V AC switch power is built in, and the high precision balance circuit can supply larger current up to 850mA per cell. Double colour LED can display the process of charging (RED: charging; GREEN: full). This charger is compact and light, especially there is separated corresponding balance port for each battery pack.
1. Please firstly connect the B3 Pro charger to power, while the three power LEDs will turn from red to green, which indicating that the charger works in good order.
2. (Set 3s battery pack for example) Secondly, please connect the battery pack to 3s balance port , while the three power LEDs will all turn into red and charging begins. Please note once the charging of one cell is done, the corresponding power LED for it will turn green.
3. When the three power LEDs all turn green, the charging for 3S battery pack is Finished.
