Description

The B3 Compact Balance Charger is a simple and easy-to-use charging solution designed for 2S and 3S LiPo battery packs used in FPV drones, RC aircraft, helicopters, cars, and hobby electronics. With its built-in AC power supply, the charger can be directly connected to standard 100–240V mains power without requiring an external adapter or separate 12V power source.

Designed for convenient plug-and-use operation, the charger automatically detects the voltage of the connected battery through the balance connector and begins the charging process. LED indicators provide clear charging status information throughout operation. Once powered on, the LEDs initially glow green and then switch to flashing red to indicate the charger is ready. During charging, the corresponding battery cell indicators remain solid red, and once an individual cell is fully charged, its LED changes to green. When all LEDs turn green, the battery charging process is complete.

Designed with a compact form factor and simple operation, the B3 charger is suitable for users charging 2S and 3S LiPo battery packs for drones, RC aircraft, helicopters, and FPV applications.
