Product description

Surgical Precision for 12V & 24V Mastery The JK-BD4A8S4P brings the advanced features of industrial-grade BMS technology to smaller, focused battery builds. By specializing in the 4S-8S range, this board remains compact and exceptionally efficient. Its 0.4A active balancer is a major upgrade over traditional passive boards, ensuring your LiFePO4 or Li-ion cells remain perfectly matched even after years of use. Key Technical Advantages: Active Energy Transfer (0.4A): Unlike standard passive BMS boards that bleed off energy as heat, this active system moves charge from high-voltage cells to low-voltage ones. This keeps the battery pack cooler and ensures maximum usable capacity. Perfect for 12V & 24V: Whether you are building a 4S (12.8V) lithium upgrade for your camper or an 8S (25.6V) bank for a small off-grid cabin, this BMS provides the perfect management layer. Cool-Running 40A Output: Engineered for high thermal efficiency, the 40A continuous rating supports loads and inverters up to 500W-1000W while maintaining a low operating temperature. Smart App Monitoring: Connect instantly via Bluetooth to the JK BMS App. Monitor individual cell voltages, State of Charge (SOC), and temperature sensors. Customize your protection thresholds for overcharge, over-discharge, and temperature on the fly. Technical Specifications: Cell Support: 4S to 8S (LiFePO4 / Li-ion / LTO) Continuous Current: 40A Peak Discharge: 60A Active Balancing: 0.4A (Energy Transfer) Connectivity: Integrated Bluetooth, support for external RS485/CAN/GPS modules.
