iMax B3 LiPo Balance Charger 2-3S

A LiPo pack's individual cells need to charge in balance with each other, not just as one combined pack voltage, or the cells drift apart over repeated cycles and the pack's usable life and safety both suffer. The iMax B3 handles that balance charging directly through its built-in XH plug ports, sized specifically for 2S and 3S packs - the most common cell counts in smaller multirotor and RC car/plane builds - without the added cost or bulk of a charger built for larger 6S+ packs.

Three LED indicators (orange for power-on, green for standby or full charge, red for actively charging) give clear status at a glance without needing a display screen to read, keeping the charger simple and genuinely compact. Running directly off 100-240V AC mains power means it works internationally without a separate adapter, useful for anyone sourcing or traveling with RC gear across different countries' outlet standards.

Common uses are charging smaller 2S-3S LiPo packs for mini and micro drones, RC car and plane battery charging where a full-size multi-chemistry charger is unnecessary capability, and genuinely portable field charging where compact size matters more than charge speed or capacity.
