The Original JK 100A (200A Peak) Universal Smart BMS with 0.6A Active Balancer

The Original JK 100A Smart BMS is a universal, high-efficiency battery management system designed for LiFePO4, LTO, Li-ion, and LiPo battery packs. Equipped with a built-in 0.6A active balancer, this BMS ensures precise, fast, and energy-efficient cell balancing. It supports wide battery configurations from 8S to 20S, making it suitable for a variety of large-capacity battery systems such as EVs, scooters, solar energy storage, backup power, and industrial applications. The integrated Bluetooth allows real-time monitoring through Android and iOS apps, and CAN/RS485 connectivity enables smart integration with inverters and remote monitoring systems.
