6A Hybrid Active Equalization BMS 3S to 17S Universal Balancer for Lifepo4 18650 Lithium Battery Maintenance

### Product Features 1. Available in 3S/4S/6S/8S/17S models, fully compatible with ternary lithium, lithium iron phosphate (LiFePO4) and lithium titanate batteries. 2. Adopts advanced hybrid balancing technology for simplified operation: no pre-detection of battery voltage difference required. It transfers energy directly through adjacent capacitors and performs high-frequency parallel connection. Equipped with single-chip microcontroller main control and low-resistance MOS tubes, it boasts ultra-low power consumption and high-efficiency, high-precision balancing performance. Long-term balancing accuracy reaches 0.005V-0.01V, with very low circuit power consumption. 3. Operating power consumption is only 1.5-2.5mA. It will automatically shut off when the cell voltage is lower than 2.5V, or you can turn it off manually via the switch. 4. Maximum balancing current is up to 6A, which varies with voltage difference: ~6A at 1V difference, ~3A at 0.5V difference, ~1.2A at 0.2V difference (the above parameters are measured on 4S power lithium batteries with 10CM 0.75mm² cables, voltage acquisition point is the on-board plug). 5. Supports flexible expansion: you can select module combinations according to your battery series connection setup, reduce or expand modules as needed, or cascade multiple boards for higher series count requirements. Please refer to the product diagram for specific connection methods.
