HA02 Balancer/Equalizer for 4 Batteries

Active Battery Balancer (Equalizer) HA02 is designed for all types of rechargeable batteries (lead and lithium) with voltages from 2.4 to 12V, which are connected in series to maintain the voltage balance between batteries. One balancer can be connected to up to 4 batteries at the same time.
When two or more battery blocks are connected in series, the voltage of the blocks during charging and discharging may vary. By cyclic operation, the battery voltage is different from one block to another. One battery has a higher voltage and one battery has a lower voltage. This condition causes irreversible damage to the batteries.
Battery balancer balances with each other - balances to max. 10mV voltage difference between batteries. This will improve the performance and battery life of the battery pack.

The Balancer operates at high frequencies, so it can emit high-frequency sound during operation, so it is not suitable for living spaces.
