This 5S Battery Management System is built around the BM3451TNDC-T28A chipset, optimized for 3.7V lithium batteries. It features precise voltage thresholds, integrated 60mA cell balancing, and a full protections against overcharge, over-discharge, short circuit, overcurrent, temperature, and disconnection safety.
It supports both same-port and separate-port wiring. With 15 ultra-low resistance MOSFETs (8 for discharge, 7 for charge), it handles up to 60A continuous (same-port) or 80A discharge (different-port).Technical Specifications
