Product description

The HBJ 3S 50A Hardware BMS is built for 3S lithium-ion battery packs using 3.7V nominal cells, giving a 12V-class battery system for high-current starting duty. It supports 50A continuous discharge and bursts to 300A peak, which is what separates a starter BMS from a general-purpose protection board. Cranking a petrol engine pulls an enormous current for a fraction of a second; a 30A or 50A board without real surge headroom trips or fails under that load. This one is specified for it. Heavy-duty hardware construction carries the surge without excessive heating or voltage sag, and the protection set covers overcharge, over-discharge, overcurrent, short circuit and abnormal temperature - disconnecting the pack before cells are damaged and restoring once conditions normalise. Typical uses are self-start petrol motorcycles, bikes, scooters, ATVs, generators and other 12V starting systems that need high peak current. This board is Li-ion only - it is set for 3.7V nominal cells and must not be used with LiFePO₄ packs, whose charge and cut-off voltages are different.
