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.

FAQ

Q1: How to maintain your lithium battery balancer?

Regular maintenance preserves the battery balancer's accuracy and service life. Wipe the casing and clean connection terminals/connectors with a dry soft cloth to prevent dust, oxidation and poor contact. Inspect wires and connectors frequently for looseness, cracks or damage, and replace faulty parts promptly. Operate the balancer within its rated specs to avoid overheating, and store it in a dry, ventilated, dust-free area away from high temp, humidity and strong vibration. Power off the device when not in use to prevent internal part aging. 

Q2: How to troubleshoot issues with lithium battery balancer?

Start by checking all connections for tightness and inspecting wires for looseness or damage, as poor wiring often disrupts balancing performance. Confirm the balancer is fully compatible with your battery type and voltage, then use a multimeter to test individual cell voltages and ensure they fall within the rated range. Next, verify the balancer's programming matches your battery pack specs, check for error codes or indicator light anomalies and refer to the user manual for solutions. If possible, test the balancer with a functional battery pack to eliminate device malfunction as a cause; if problems persist, please contact technical support, and replace faulty components or the entire unit if troubleshooting fails.
