Product Description


HA02 battery equalizer is used for the batteries which are connected in series to keep the voltage of batteries are equal when 

the batteries are charging or discharging. When the batteries work in series connection, the batteries voltage 

maybe will be not same due to the difference of each cell chemical composition and temperature. 

And each battery’s self discharge rate also different. So even the batteries not work, their voltage of series batteries will be also different. 

These differences will cause battery lost balance, this means maybe one battery is overloaded and the other is 

insufficiently charged. The voltage difference will be increased with the battery repeated charge discharge process. This will result in premature failure of the batteries.




•Energy transfer type equalizer.


• Apply to different type of battery systems.


• Apply to any n*(2.4V/3.6V/6V/9V/12V) batteries.


• No damage to the battery

• Very low power consumption

• Reverse polarity protection

• Moisture-proof and waterproof
