BCA B3 Pro Lipo / Li-ION 20W Smart Charger (2/3 Cells)

BCA B3 LiPo Balance Smart Charger is a compact, mains-powered automatic balance charger engineered specifically for 2-cell (2S / 7.4v) and 3-cell (3S / 11.1v) Lithium Polymer (LiPo) and Lithium Ion (Li-ION) battery packs.

Incorporating an internal 100V-240V AC switching power supply and three independent precision cell-balancing channels (up to 850mA per cell), the BCA B3 charges each individual cell through its JST-XH balance lead to ensure uniform 4.20V termination across the entire battery pack. Three dedicated bi-color LED indicators provide real-time per-cell charging status for compatible LiPo/Li-ION battery packs.

Key Features:

• Independent 2S & 3S Balance Ports: Dedicated 3-pin and 4-pin JST-XH balance sockets charge each cell individually. Please note that the charger can only charge one battery at a time. Do NOT plug more than one JST-XH connector into the battery at a time.
• Built-In Universal AC Power Supply: Connects directly to 100V-240V AC (50/60Hz) household mains via the included AC power cord. No external adapter required.
• 3x 850mA Fast Balance Current: Upgraded 20W internal power stage delivers up to 850mA per cell channel for rapid, balanced replenishment.
  
• Tri-LED Cell Status Display: Three dual-colour (Red/Green) LEDs independently indicate charging status for Cell 1, Cell 2, and Cell 3.
  
• Automatic 4.20V Cut-off & Protection: Built-in short-circuit, overcharge, and reverse-polarity protection automatically stops charging when cells reach 4.20V.
