    Description

    The 3-8S Lithium Battery Balancer Module is designed to maintain equal voltage across multi-cell lithium-ion and lithium polymer battery packs ranging from 3S to 8S configurations. By providing a steady 100mA balancing current, this module ensures that each individual cell charges and discharges evenly, which significantly enhances battery efficiency, safety, and lifespan. It supports popular lithium cells such as 18650 and 26650, making it suitable for high-power systems including electric vehicles, drones, and power tools. This balancer operates within defined voltage ranges for each cell configuration and automatically equalizes higher-voltage cells during charging. Featured By RoboticsBD.
