12S 5A Lipo Battery Balancer, Active Balancing

The cost-effective 5A Lipo battery balancer is a high-value performance enhancer specifically designed for 12-series lithium polymer battery packs! It features a flexible balancing current range of 0–5A, enabling precise voltage regulation for each cell, effectively eliminating voltage differences that can reduce battery performance and lifespan. This powerful accessory can seamlessly integrate with most Battery Management Systems (BMS), acting as a reliable guardian for your lithium polymer batteries—extending their cycle life, improving overall efficiency, and ensuring stable and long-lasting operation.

Feature

• Active Balancing Type: Active battery balancers support large batteries or energy storage systems, with diversified application scenarios.
• High-quality Components: Built-in high-quality capacitors for more sensitive and efficient induction.
• User-friendly Design: Easy to install. Equipped with a balancing indicator light, the working status is clear at a glance.

Details

1. Pre-drilled Mounting Points: No extra drilling required! Pre-aligned screw holes make installation a breeze, cutting down assembly time and effort.
2. Foolproof Clip-on Wiring: Plug-and-play connectors that can’t be inserted wrong—say goodbye to short circuits. The clip-on design locks cables in place, so they stay secure even under vibration.

Notes: Please solder and inspect the cable harness independently first. Only after confirming there are no errors should you plug in the balancing module.

1. Solder the Cable Harness: Start connecting the cable harness from the main negative terminal B-. Then, connect the second black wire (first red wire) to the positive terminal of the first battery string, and continue connecting to the positive terminals of each subsequent battery string in sequence, until the last red wire is connected to the main positive terminal B+.
2. Measure the Voltage: After connecting the entire cable harness, use a multimeter to check that the voltage of each string and the total voltage are within the normal range (3.0~4.15V for ternary lithium batteries, 2.5~3.6V for LiFePO4 batteries). If the voltage is abnormal, check for soldering issues such as cold solder joints, false soldering, or uneven solder points. Only after confirming the voltage is normal can you plug in the active balancing module.
3. Start Using: Active balancing module will activate automatically when powered on. If the cable harness becomes disconnected, you will need to power it off and on again to reactivate. The module will automatically start balancing when the voltage of any battery string is ≥3.1+0.1V and stop when it drops to ≤3.0+0.1V. The green indicator light will be on when balancing is active and off when it is inactive.
