3S 10A SLCT Li-ion Battery Management System (BMS)

Overview:
The 3S 10A SLCT Li-ion BMS is a compact and reliable battery management system designed for lithium-ion battery packs configured in 3 cells in series (3S). It supports up to 10A continuous discharge current and provides essential protections including overcharge, over-discharge, overcurrent, and short circuit protection. The BMS also features passive balancing to maintain cell health and performance over time.
