GOOWEI ENERGY balancer HA02
The HA02 active battery balancer (equalizer) is designed for all types of rechargeable batteries (lead, lithium, VRLA, LFP) with voltages from 2.4 to 12 V , which are connected in series to maintain 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 voltages of the blocks may be different during charging and discharging. Cyclic operation causes the battery voltages to be different between the blocks. One battery has a higher voltage and one battery has a lower voltage. This condition causes irreversible damage to the batteries.
The battery balancer equalizes the voltage of the batteries - it balances them to a maximum voltage difference of 10 mV between the batteries. This improves the performance and lifespan of the batteries connected in the battery pack.
The balancer works with high frequencies, so it can emit high-frequency sound during operation, so it is not suitable for residential areas!

A balancer is a protective device that maintains the voltage balance between individual batteries in a series connection (the voltages of the batteries are added together). When two or more battery blocks are connected in series, the voltages of the blocks during charging and discharging may be different. Cyclic operation causes the battery voltage to be different between the individual blocks. One battery has a higher voltage and one battery has a lower voltage. This condition causes irreversible damage to both batteries. A battery balancer balances the voltage difference between the two batteries, thereby improving the performance and life of the batteries connected in the battery pack.
Passive balancer: draws current from the higher voltage battery and converts it into heat until the voltage matches the lower voltage battery(s).
Active balancer: moves energy from a higher voltage battery to a lower voltage battery/batteries, making the entire voltage balancing process more efficient and faster.
