B3 AC Compact Balance Charger for 2S-3S LiPo

Description

[Uncategorized] The B3 Compact charger is a very simple to use charger for 2S and 3S battery packs. No need for additional power supplies or 12v batteries as this little unit has its own built-in power supply that can be powered with 100-240v. The 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.
