Active Balancer 3–4S 3A Battery Equalizer
Keep your lithium battery packs performing at their best with this Active Balancer 3–4S 3A Battery Equalizer. Designed for 3S and 4S Li-ion, LiPo, and LiFePO4 batteries, this device ensures each cell is charged and discharged evenly, extending battery life and improving overall efficiency. Unlike traditional passive balancers that waste energy as heat, this active balancer transfers energy between cells in real time, providing fast and efficient balancing at up to 3A.
Perfect for use in DIY battery packs, drones, solar systems, e-bikes, and energy storage projects, this equalizer prevents cell overcharging and over-discharging, reducing the risk of damage and increasing pack stability. Easy to install with a simple plug-and-play design, it’s an essential tool for anyone working with multi-cell lithium batteries.
