The B3 Pro Lithium Polymer/Lithium-Ion battery charger is a simple and compact device that features built-in JST-XH balance plug ports and 3 LEDs to indicate charge status. The high precision balance circuit in the charger can provide up to 850 mA current each to the 3 batteries. This B3 Compact charger is very simple to use for charging 2S and 3S battery packs. This charger needs no additional power supplies as it has its own power supply that converts 100-20 AC to 12V DC. This B3 is very easy to use, simply plug it into the mains power and the 3 LEDs will light green and then flash to red to indicate the charger is ready. Connect the balance lead of your battery to the balance port of the charger, after 2 secs the charger detects the voltage of the battery and starts charging. When the charger starts charging the LEDs will glow constant red, if the battery is a 2 cell then the cell LED indicators 1 and 2 will glow constantly if it is a 3 cell then the cell 3 LED indicator will also glow. When a cell is completely charged the corresponding LED will turn green, when all cells turn green the battery is fully charged, disconnect the battery before switching off the charger.
