B3 PRO LIPO Battery balance Charger

Compact 2S & 3S LiPo Balance Charging: Specifically engineered to charge 2-cell (7.4V) and 3-cell (11.1V) Lithium-Polymer (LiPo) battery packs with high balance accuracy.

Integrated Cell Balancing: Features independent internal balance ports that monitor and equalize individual cell voltages throughout the charging process, extending battery life and performance.

Direct AC Mains Power Supply: Features an internal power module that plugs directly into standard wall outlets (100V–240V AC), eliminating the need for external power bricks or AC adapters.

Simple Plug-and-Play Operation: Automatically initiates charging when connected to a battery pack via its JST-XH balance lead—no complex programming or menu navigation required.

Individual LED Status Indicators: Equipped with three multi-color LED indicators (one for each cell slot) providing real-time visual feedback (red for active charging, green for full charge/standby).

Protective Circuit Safeguards: Built-in protection against short-circuiting, overcurrent, overvoltage, and reverse polarity for safe desktop charging.

Housing & Casing Style: Flame-retardant ABS plastic casing with side ventilation slots for passive heat dissipation.

Contact & Terminal Style: Onboard standard 2S and 3S JST-XH balance pin socket ports and standard 2-pin AC power inlet.

Technical Specifications:

Input Voltage: 100V–240V AC (50/60Hz).

Max Charging Current: 3 x 800mA (Max 10W total).

Supported Battery Types: 2S (7.4V) and 3S (11.1V) LiPo cells.

Color: Black housing with orange and white label graphics.

Usage Advice: Connect the AC power cable first until the LEDs turn green, then plug your battery's JST-XH balance lead into the corresponding 2S or 3S port. Never plug two batteries into the board at the same time.

Maintenance: Keep the balance sockets clean and free of dust or moisture. Unplug from the AC wall outlet when not actively charging.

Essential Entry-Level RC Companion: Position as the ultimate entry-level, hassle-free balance charger for RC car drivers, airsoft enthusiasts, and beginner FPV drone pilots using 2S or 3S LiPo packs.

Highlight AC Portability & Automatic Balancing: Emphasize the ease of direct AC wall-plug operation combined with automatic cell-balancing safety that preserves battery pack health without setup headaches.

Recommended Cross-Sell Add-ons: Pair with B3 20W 2-3S Lipo Battery Compact Charger, JST-XH 2s-6s LiPo battery charger board, (XT-60) Parallel charging Board 2~6S, and ESD antistatic mat 50x40CM PCB Welding Mat.
