JK-B1A8S20P-HC 4S-8S 200A Smart BMS, 1A Active Balance, CAN & Heating | High-current monitoring and inverter-ready control for RV, marine, golf cart, solar storage and backup power systems

1A Active Balancer Enhances Battery Performance: The integrated 1A active balancer transfers energy between cells rather than dissipating it as heat. This aids in reducing cell voltage differences, improving battery uniformity, and boosting LiFePO4 battery performance. Smart Bluetooth Monitoring: Track battery voltage, current, state of charge (SOC), temperature, cycle capacity, and balance status in real-time via the mobile application. The built-in Bluetooth design removes the requirement for external Bluetooth modules. Built-in Heating for Cold Weather Charging: The incorporated heating function assists in protecting LiFePO4 batteries during low-temperature charging, making it appropriate for RV camping, off-grid solar storage, marine, and winter outdoor uses. 200A High Current for Multiple Applications: Supports 4S-8S 12V and 24V lithium battery packs for applications including RV solar energy storage, trolling motors, marine backup power, DIY battery systems, and off-grid setups. Advanced Protection with CAN & RS485: Supports CAN and RS485 communication for integration with inverters, displays, and energy systems. It offers protection against overcharge, over-discharge, overcurrent, short circuit, and temperature extremes
