Product description

The HBJ 4S 30A Hardware BMS is purpose-built for 4S LiFePO₄ battery packs, delivering dependable protection and stable performance for 12V-class lithium iron phosphate battery systems. Rated for 30A continuous discharge, it suits low-to-medium current applications that need reliable battery management without the cost or complexity of a smart BMS. The hardware-based design keeps the protection logic on-board - there is no app, Bluetooth or configuration required, which makes it dependable in fixed installations. Protection covers overcharge, over-discharge, overcurrent, short circuit and abnormal temperature, cutting the pack off before cells are damaged and reconnecting once conditions return to normal. High-current power connections and durable construction keep voltage drop and heating low under sustained load. Typical uses include solar energy storage banks, UPS and backup systems, portable power boxes, DIY 12V LiFePO₄ packs and small inverters. Note that this board is LiFePO₄-only - do not use it with 3.7V Li-ion or Li-polymer cells, whose charge voltages differ.
