The amiciSolar 24V 6S 40A BMS Protection Board is a high-performance Battery Management System designed to protect and optimize 6-cell lithium-ion battery packs, including 18650 and 21700 cells. With a 40A continuous discharge capacity and up to 75A peak protection, this BMS is built for demanding applications like solar lighting systems, e-bikes, power tools, and energy storage projects.
Equipped with active cell balancing technology, it ensures cells remain balanced within ±30mV accuracy, with a 41mA balancing current that activates at 4.125V. The system stops balancing once cells are equalized, preventing unnecessary energy loss and extending battery lifespan.
