Lithium Battery Charger Protection Module (BMS) 10S ( 36V – 30A )

10S Lithium Battery Charger Protection Module (BMS) – 36V 30A

The 10S BMS (Battery Management System) is designed for 10-cell lithium-ion or lithium-polymer battery packs connected in series (10S = 36V nominal, 42V when fully charged). With a continuous discharge rating of 30A, it is well-suited for high-power applications like electric bikes, scooters, solar storage systems, and DIY energy packs.
