5.5A Current Active Balancer 12S Equalizer Lithium Ion Lifepo4 LTO Lithium Battery Active Equalizer Balance Board
Li-ion BMS generally have a passive equalization function, but the equalization current is usually less than 100mA. And the latest active balancing home storage BMS launched by Enerkey, the balancing current is increased to 5A (5000mA), which greatly improves the balancing efficiency.
Different from passive balance and other active balances, Enerkey active balance home storage BMS adopts energy transfer type active balance.
This technology has two major advantages:
1. Less heat generation, low-temperature rise, and high safety factor;
2. Cut high and fill low (transfer the energy of the high-voltage battery cell to the low-voltage battery cell), and the energy is not wasted.
Thanks to this, the lithium battery equipped with Enerkey 's active balancing home storage BMS can store energy for the home energy storage system more permanently and reliably.

NOTE:As shown in the figure above,there can be multiple common ends of energy exchangeso that the efficiency of equilibrium will be higher;It is also possible to use only one common end of theenergy exchange atthejunction of two modules.The other free feet are suspended, and it is best todistribute the number of strings equally on each board.If you need the cascade diagram for more strings, Please contact our online service, Thanks.
