Product description

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. Specifications at a Glance: Cell Configuration: 4S to 8S (LiFePO4, Li-ion, LTO) Continuous Discharge: 200A Peak Discharge: 400A Active Balancing: 0.1A – 2.0A Communication: Bluetooth (Standard); supports CANBus/RS485 customization.
