PGY-141 8–24S 60–200A
The PGY-141 is a software-based active balancing Battery Management System (BMS) designed for 8 to 24 series lithium battery packs. It supports 60–200A continuous charge and discharge current and features energy-transfer active balancing, which redistributes energy between cells instead of dissipating it as heat. By continuously monitoring cell voltage, temperature, and operating status, the PGY-141 significantly improves battery pack consistency, usable capacity, and cycle life, making it suitable for high-capacity and high-current lithium battery systems.
