Product description

Heavy-Duty Performance for Vehicle Cranking & Parking Power The JK-QB2A8S20P is specifically designed for users who need industrial-grade current handling and specialized automotive control at lower voltages. With the addition of a 30V supercapacitor, the maximum starting current can reach 2500A. While standard lithium boards struggle with high inrush currents, this specialized model is built for vehicle starting and parking applications. Why Choose the JK-QB2A8S20P? Integrated Charge Current Limiting: In particular, when dealing with high-output alternators, uncontrolled charging can damage a lithium battery. This BMS solves that issue by restricting input current, thereby protecting both the battery cells and your vehicle's charging system from overheating. Proactive 2A Active Balancing: In contrast to passive boards that slowly bleed off excess energy as heat, the integrated 2A balancer actively reshuffles charge from strong cells to weaker ones. As a result, this maximizes your usable capacity, which is critical when utilizing large-format prismatic cells. Dedicated Vehicle Starting Logic: Because it is optimized for dual-purpose cranking and deep-cycling, this unit handles intense high-amperage surges during ignition while maintaining absolute cell safety. Smart App & Precision Protection: Through the built-in Bluetooth and intuitive JIKONG App, you can monitor individual cell health in real-time. Moreover, you have full customization rights over the safety thresholds, allowing you to fine-tune your overcurrent, overvoltage, and thermal management parameters with ease. Technical Specifications: Cell Support: 4S to 8S (LiFePO4 / Li-ion / LTO) Continuous Current: 200A Maximum Starting Current: 2500A (with 30V supercapacitor) Active Balancing: 2A (Energy Transfer) Connectivity: Bluetooth, Charger check, Display, Forced start switch, GPS Support, Heating Function
