12V Battery Balancer


The 12V battery equalizer is an active balancer designed to equalize lead-acid battery packs, connecting two batteries and equalizing their voltages during operating and idle times, thus improving battery performance and service life.

A battery equalizer is a device used to equalize the voltage of a battery pack. An effective configuration of the equalizer can make the battery pack work more consistently and last longer.

Features of Battery Balancer 12V

HA12 battery Balancer can compensate both parties when the battery is connected in series as the voltage difference exceeds ten mV, then the battery equalization starts to work, finally achieving the balance of the battery set. It can be connected for long periods to automatically battery state of equilibrium.

HA12 battery equalizer is suitable for lead-acid batteries(VRLA), lithium iron phosphate batteries(LiFePo4), nickel-cadmium secondary batteries(Ni/CD), and nickel metal hydride secondary batteries(Ni/MH).

It starts working when the voltage is higher than 2.4V, which means that this equalizer can be used in a single-cell battery ranging from 2.4V to 12V.

The equalizer is not affected by battery connection way; no matter whether in series or in parallel, both can work.
