1.Energy transfer type equalizer.

It can compensate for batteries with two sides. The equalizer starts to work when there are 10mV between two batteries. The current will flow from a higher voltage to low voltage, eventually reach equilibrium. It can connect with battery system with 24 hours, to keep the system energy balance automatically, no need manual maintenance.

2. Apply to different type of battery systems.
HA02 battery equalizer is suitable for lead-acid batteries (VRLA), lithium iron phosphate batteries (LFP), nickel-cadmium secondary batteries (Ni/CD), and nickel-metal hydride secondary batteries (Ni/MH).

3. Apply to any n*(2.4V/3.6V/6V/9V/12V) batteries.
It starts work when the voltage higher than 2.4V, it means that this equalizer can be used in a single cell battery range from 2.4V to 12V. One equalizer can connect 4 batteries once a time, if battery less than the 4, the extra cable can be vacant (positive and negative terminal should be avoided), does not affect the equilibrium effects. The equalizer is not affected with battery connection way, no matter in series or in parallel, both can work.

4. No damage to the battery

5. Very low power consumption

6. Reverse polarity protection

7. Moisture-proof and waterproof
