Battery Repairer 2-24S 3A 4A Lithium Battery Automatic EqualizerBattery Repairer

This equalizer applies to 2-24 series lithium battery, from 1.5V~4.5V Ternary lithium, Lithium iron phosphate, Titanium cobalt lithium battery.

The equalizer starts the compensation with a button, stops automatically after the compensation is complete, and then warns. When the voltage is out of the range, it will sound a warning and display reverse polarity warning and reminder: after connection reverse, over-voltage (greater than 4.5V), low voltage (less than 1.5V).

The equalizer does not charge the batteries during the balancing process. So do not worry about the risk of overloading. The speed of the whole balancing process is the same, and the balancing speed is fast.

  • Discharge balance, no risk of overloading.
  • Fast and simultaneously balancing.
  • Constant resistance 1 ohm discharge balancing.


Since the balancing method is to discharge the high-voltage string energy, until it is equal to the lowest voltage string, the excess energy is wasted.

Battery maintenance steps

It is a bad battery cell:

1) replace the battery cell;

2) fully charged;

3) balance;

4) fully charged;

5) battery maintenance completed.

* We keep upgrading products to meet requirements of our clients, please contact our sales person for more accurate details.


Before balancing, please check if the lowest voltage is lower than the battery over-discharge voltage. If it does, please charge the batteries first; and when the batteries is fully charged, start balance, and the effect will be better.
