AJMRTC 4S 14.8V 20A Peak BMS PCM is a dedicated lithium battery protection management board for 4-series LiCoO2 and LiMn2O4 lithium-ion cells. The full charge voltage of the battery pack is 16.8V and nominal voltage is 14.8V. This BMS module integrates multiple safety protection mechanisms including overcharge protection, over-discharge protection, over-current protection, short circuit protection and thermal protection. It cuts off the circuit automatically once abnormal status occurs to prevent battery damage and safety hazards. Adopting high-performance power MOSFETs with low internal resistance, the board can support peak current up to 20A. It is suitable for DIY lithium battery packs, portable power stations, small power equipment and energy storage projects. Please note that cell matching is required before assembly.
