With an integrated AC supply, the iMaxRC B3 Pro Compact LiPo Balance Charger handles 2S and 3S battery packs. Drawing 100-240V from any wall outlet, the unit charges lithium-polymer cells independently. To reduce downtime, this revision increases output to 800mA and 10W.
Key Features
- Individual Cell Balancing: 2S and 3S packs receive current per individual cell. Prevents battery swelling during high humidity usage.
- Automatic Current Cut-off: Circuitry terminates power once cells reach 4.2V. Stops thermal runaway without user monitoring.
- Integrated AC Supply: 100-240V hardware sits inside the 160g polymer case. Eliminates the need for external power bricks.
- LED Status Indicators: Three bicolor lights display charging state per cell. Identifies faulty cells through clear color changes.

Connect the AC cord and wait for green LEDs. Insert the JST-XH balance plug into the 2S or 3S port.
What do the lights on B3 Pro charger mean?
Steady red light indicates active charging for that specific cell. Solid green means the cell reached full 4.2V capacity.
Can B3 Pro charge 4S batteries?
No, the internal circuitry only supports 7.4V and 11.1V packs. A 4S connection will cause immediate hardware failure.
