1.5A 21S Lithium Battery Active Equalizer Balance Capacitor Board

The1.5A 21S Active Inductive Balance Board is designed to maintain voltage balance across four lithium battery cells, improving overall battery efficiency and lifespan. Using active energy transfer technology with a balance capacitor, it redistributes energy from higher-voltage cells to lower-voltage ones instead of wasting power as heat. 1.5A 21S Active Inductive Balance Board This ensures stable performance, better safety, and longer cycle life for lithium battery packs. Compact and easy to integrate, this balancer is ideal for Li-ion and LiFePO4 battery systems used in electric vehicles, solar storage, UPS systems, and DIY battery packs. Features: Active balancing with energy transfer technology Supports 21S lithium battery packs 1.5A balancing current for fast equalization Improves battery lifespan and performance Reduces heat loss compared to passive balancers Compact, lightweight, and easy to install Package Includes: 1 x 1.5A 21S Lithium Battery Active Equalizer Balance Capacitor Board1 x Connector/Terminal Wire
