B3 20W 2-3S Lipo Battery Compact Charger

Upgraded 20W High-Power Balance Output: Delivers up to 20W total output power with an upgraded charging current (up to 1.6A max), providing faster charging times for 2S and 3S LiPo packs compared to standard 10W chargers.

Dedicated 2S & 3S LiPo Compatibility: Specially engineered to balance charge 2-cell (7.4V) and 3-cell (11.1V) Lithium-Polymer (LiPo) battery packs across micro and mid-sized RC setups.

Integrated Individual Cell Balancing: Built-in high-precision micro-processor balance circuitry independently monitors and equalizes each cell's voltage to preserve cell health and maximize overall battery cycle life.

Direct AC Mains Power Input: Features an internal power module that plugs directly into standard household outlets (100V–240V AC) with the included AC power cable, eliminating the need for external power bricks.

Tri-Color LED Status Monitoring: Equipped with dedicated LED indicators for each cell slot, providing real-time charging visual status (red for charging, green for full charge/standby).

Comprehensive Protective Circuitry: Built-in safeguards protect against short-circuit, overcurrent, overvoltage, and reverse polarity for reliable desktop charging.

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

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).

Circuit Power: 20W Max.

Max Charge Current: Up to 1.6A.

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

Color: Black plastic casing with red and white logo graphics.

Usage Advice: Connect the AC power cable first until all LEDs turn green, then plug your battery's JST-XH balance connector into the corresponding 2S or 3S port. Never attempt to charge two batteries simultaneously.

Maintenance: Keep balance ports free of dust, dirt, and moisture. Store in a cool, dry area and unplug from the AC outlet when not actively charging.

Essential High-Speed Desktop Charger: Position as the upgraded 20W balance charging solution for RC vehicle drivers, airsoft players, and drone pilots looking for faster charge cycles than base 10W models.

Highlight 20W Power & Direct AC Input: Emphasize the doubled power output combined with convenient direct AC wall-plug operation without needing extra power supplies.

Recommended Cross-Sell Add-ons: Pair with B3 PRO LIPO Battery balance Charger, JST-XH 2s-6s LiPo battery charger board, (XT-60) Parallel charging Board 2~6S, and A400 40W Battery Balance Charger 3-4S.

Featured Collection Hero: Display prominently on your HTRC Charger/Discharger collection page as your featured 20W multi-cell balance dock.
