Smart Battery Management System for Solar Lighting, Energy Storage with Active Cell Equalization BMS Protection Board for Li-Ion Battery Packs

Tired of unbalanced cells killing your battery pack early? The amiciSolar 24V 6S 40A BMS Protection Board actively balances every cell and guards against every major fault — so your lithium pack lasts longer and performs harder.

The amiciSolar BMS is purpose-built for 6-cell (24V) lithium-ion packs using 18650 or 21700 cells. It delivers 40A continuous discharge with up to 75A peak protection, making it robust enough for solar energy storage, e-bikes, DIY power walls, and off-grid lighting systems. Unlike passive balancers that waste energy as heat, this board uses active cell equalization at ±30mV precision with 41mA balancing current — automatically redistributing charge between cells to extend overall pack life significantly.

Safety is built in at every layer: overcharge protection at 4.25V, over-discharge cutoff at 2.7V, overcurrent and short-circuit protection with automatic recovery, and a main circuit resistance of just ≤20mΩ to minimise heat and power loss. The wide operating temperature range of -30°C to 80°C means it handles Indian summer heat, cold storage environments, and everything in between without breaking a sweat. Whether you're a solar DIY enthusiast, an e-bike builder, or an electronics hobbyist, this BMS gives you professional-grade protection in a compact, easy-to-wire board.
