It charges each cell individually through the balance connector, ensuring all cells reach the same voltage (4.20V ±0.05V per cell) for safe, balanced charging without requiring a separate power supply or complex settings. Simply plug into a wall socket and connect your LiPo pack — the B3 handles the rest.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Specifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInput voltage: AC 100V – 240V (universal mains)\u003c\/li\u003e\n\u003cli\u003eCompatible battery types: LiPo, Li-ion, LiFe (2S and 3S only)\u003c\/li\u003e\n\u003cli\u003eCell count: 2S (7.4V) and 3S (11.1V)\u003c\/li\u003e\n\u003cli\u003eCharge current: ~400mA per cell (2S), ~350mA per cell (3S)\u003c\/li\u003e\n\u003cli\u003eCharge cutoff voltage: 4.20V ±0.05V per cell\u003c\/li\u003e\n\u003cli\u003eConnector: JST-XH balance connector (2S: 3-pin, 3S: 4-pin)\u003c\/li\u003e\n\u003cli\u003eCharge indication: LED per cell (red = charging, green = full)\u003c\/li\u003e\n\u003cli\u003eNo power supply required — plugs directly into AC mains\u003c\/li\u003e\n\u003cli\u003eDimensions: ~75mm × 45mm × 30mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eLED Indicators:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRed LED: cell is charging\u003c\/li\u003e\n\u003cli\u003eGreen LED: cell is fully charged\u003c\/li\u003e\n\u003cli\u003eAll green: pack is fully balanced and charged — safe to disconnect\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCompatible Battery Packs:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2S LiPo (7.4V) — connect to 3-pin JST-XH balance port\u003c\/li\u003e\n\u003cli\u003e3S LiPo (11.1V) — connect to 4-pin JST-XH balance port\u003c\/li\u003e\n\u003cli\u003eNot compatible with 1S, 4S, or higher cell count packs\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRC cars, trucks, and buggies\u003c\/li\u003e\n\u003cli\u003eRC aircraft and fixed-wing planes\u003c\/li\u003e\n\u003cli\u003eFPV drones and quadcopters (2S\/3S)\u003c\/li\u003e\n\u003cli\u003eRC boats and watercraft\u003c\/li\u003e\n\u003cli\u003ePortable LiPo-powered electronics\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSafety Notes:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eNever leave charging LiPo batteries unattended\u003c\/li\u003e\n\u003cli\u003eDo not charge damaged, swollen, or punctured LiPo packs\u003c\/li\u003e\n\u003cli\u003eCharge on a fireproof surface or in a LiPo-safe bag\u003c\/li\u003e\n\u003cli\u003eThe B3 charges at a low C-rate — charge times are longer than dedicated balance chargers (e.g. IMAX B6)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Embeded Studio | Pakistan's Leading Electronics Online Store","offers":[{"title":"Default Title","offer_id":60779073896818,"sku":"ES-IMAX-B3-CHARGER","price":750.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/7935\/3202\/files\/72141cb6a92c366aa8a5f4b062da3420.webp?v=1765176740","url":"https:\/\/embededstudio.com\/products\/imax-b3-lipo-battery-balance-charger","provider":"Embeded Studio","version":"1.0","type":"link"}
