2S 4A Li-ion Battery Protection BMS Module for 3.2V LFP Cells with Nickel Strips is a compact 2S battery protection module designed specifically for two LiFePO4 (LFP) cells connected in series. It supports a 6.4V nominal battery pack and approximately 7.4V maximum charging voltage, with up to 4A continuous current capability. The module provides protection against overcharge, over-discharge, over-current, and short-circuit conditions and includes nickel strips for convenient spot-welded battery pack assembly.
