The JK-BD4A8S6P is a high-performance Smart BMS engineered for 4S to 8S LiFePO4, Li-ion, and LTO battery configurations. It delivers a solid 60A continuous discharge and features a built-in 0.4A active balancer to maintain perfect cell equilibrium. With integrated Bluetooth for full app control, it is the ideal solution for marine house batteries, 24V trolling motors, and campervan lithium upgrades.

product description

Optimized Cell Health for 12V & 24V Systems The JK-BD4A8S6P brings professional-grade active balancing to small-to-medium battery builds. By specializing in the 4S-8S range, this BMS remains compact while offering a robust 60A output. Its 0.4A active balancer is a significant upgrade over traditional “passive” boards, ensuring your cells stay matched without generating excess heat.

Why Choose the BD4A8S6P?

• Active Energy Transfer (0.4A): Unlike cheap passive boards that bleed energy through resistors, this active system moves charge from high cells to low cells. This keeps the battery pack cooler and ensures you can access 100% of your rated capacity.

• Perfect for Marine & RV: Whether you are building a 4S (12V) LiFePO4 house bank or an 8S (24V) motor battery, this BMS provides the intelligence and protection needed for off-grid life.

• Reliable 60A Continuous Output: Built to handle constant 60A loads, it safely supports inverters and appliances up to 800W (at 12V) or 1600W (at 24V).

• Smart App Monitoring: Connect via Bluetooth to the JK BMS App to track individual cell voltages, State of Charge (SOC), and temperature sensors. Customize your protection limits for overcharge and over-discharge on the fly.
