Description
The 4S 6A Active Balancer Board is a high-performance battery equalization module designed for Li-ion and LiFePO4 battery packs. Unlike traditional passive balancing, it uses active energy transfer technology to move charge from higher voltage cells to lower ones, ensuring faster and more efficient balancing.
With up to 6A balancing current, it significantly improves battery lifespan, stability, and overall performance. The capacitor-based system minimizes heat loss and increases efficiency, making it ideal for high-capacity battery systems. Easy to install with screw terminals and balance wires, this module is perfect for DIY and professional battery builds.
Application
• LiFePO4 Battery Pack Balancing (4S 12V Systems)
• Lithium-ion Battery Maintenance Systems
• Solar Energy Storage Batteries
• Electric Bike / EV Battery Packs
• DIY Battery Pack Projects
