JK B2A8S20P 3S-8S Continuous Current 200A Smart Active Balance BMS

The JK-B2A8S20P is a professional Smart BMS featuring a robust 200A continuous discharge capacity and a built-in 2A active balancer. Engineered for 4S to 8S LiFePO4 and Li-ion battery packs, it provides intelligent Bluetooth monitoring and high-tier safety protection for marine, RV, and residential solar storage applications.

Optimized Power with JK-B2A8S20P Active Balancing The JK-B2A8S20P is designed to handle the heavy lifting of modern energy storage. With its 200A continuous current rating, it is perfectly suited for 2000W-3000W inverters. Unlike standard BMS units, it includes a powerful 2A active balancer that transfers energy from high cells to low cells, ensuring your pack remains perfectly equalized even under heavy cycling.

Key Technical Advantages:

• · 2A Active Equalization: Significantly faster than passive balancing, the 2A active current keeps your cells healthy, maximizes usable capacity, and prevents premature battery aging.
• · High-Current Handling: Rated for 200A continuous and 400A peak discharge, providing plenty of headroom for high-surge appliances like microwaves or power tools.
• · Intelligent App Monitoring: Built-in Bluetooth allows you to view SOC, cell voltages, and temperatures in real-time. Customize your protection settings directly through the JK BMS smartphone app.
• · Industrial Safety Suite: Integrated sensors protect against over-current, short-circuits, and extreme temperatures, providing peace of mind for off-grid installations.
