JK JK-BD4A8S6P 60A 4S-8S Smart Active Balance BMS (with Bluetooth)

Take full control of your custom battery pack with the JK JK-BD4A8S6P Smart Active Balance BMS. Engineered for maximum battery health, efficiency, and longevity, this high-performance Battery Management System supports 4S to 8S battery configurations with a 60A continuous charge and discharge current capability.

Unlike conventional passive balancers that waste energy as heat, the JK Smart BMS features 0.4A active balancing, transferring energy seamlessly between cells to ensure uniform voltage levels, extended cycle life, and maximum usable capacity.

Key Features

• Real-Time Active Balancing (0.4A): Actively transfers energy from high-voltage cells to low-voltage cells to keep all individual battery cells balanced without heat loss.

• Built-in Bluetooth Monitoring: Easily monitor total voltage, cell voltages, charge/discharge current, temperature, and SOC (State of Charge) via the mobile app on iOS and Android.

• Flexible 4S to 8S Compatibility: Ideal for 12V and 24V nominal battery systems using LiFePO4, Li-ion, or LTO chemistries.

• Continuous 60A Current: Designed to reliably handle up to 60A continuous charge and discharge loads.

• Comprehensive Multi-Protection: Advanced safety safeguards against over-charge, over-discharge, over-current, short-circuit, and high/low temperature events.

• Display Output Support: Connect an optional external display screen for convenient real-time status visibility.
