1.2A 4S Active Inductive Balance Board

The 4S 1.2A Active Inductive Balance Board is a smart battery equalizer designed for 4‑cell lithium‑ion and LiFePO4 / LFP battery packs. Utilizing active inductive energy transfer technology, it detects voltage imbalances and transfers energy from higher‑voltage cells to lower‑voltage ones, resulting in faster, energy‑efficient balancing without heating or wasting power. Unlike passive balancers, it intelligently activates and shuts down based on cell differences, helping to prolong battery life, improve reliability, and enhance safety. This module is ideal for DIY battery systems, solar storage, e‑mobility packs, and other high‑performance lithium setups Features: Active balancing for 4S battery packs. Up to 1.2A balancing capability. Automatic voltage difference detection. Improves battery efficiency and lifespan. Compact PCB for easy integration. Package Includes: 1 x 1.2A 4S Active Inductive Balance Board1 x Connector/Terminal Wire
