4S 12V Active lithium Equalizer Battery balancer



4S battery balancer4S battery balancer dimension


The Battery Balancer is a mutual energy transfer system with a high-frequency pulse working method. It is widely used for lithium-ion, lead-acid, NiMH batteries, and lifepo4 batteries.  The primary function of a battery balancer is to balance the voltage of the batteries. The battery balancer helps you improve the performance of your battery pack!



QNBBM 4S Active Battery Balancer for Lithium Lifepo4 Li-ion LTO battery packs.


1. Suitable for 3.2V Lifepo4 cells, 3.7V rated Li-ion Li-NCM Li-polymer cells and LTO cells.

2. No limitation for capacity, valid for 1000AH+.
3. 24 hours automatically dynamic equalization.
4. Keep voltage difference within 10-20mV after balanced.
5. Prolong lifespan two times.
6. Keep the cells in an excellent and healthy state.
