4S Active Equalizer Balancer with 6A Balance Current 10A Peak Current and Dynamic Energy Transfer for Lithium Ion Batteries
QNBBM Balancers equalize voltage for every series of batteries, preventing all cells from overcharge, insufficient charge, or over discharge. This technology maximizes battery performance and extends battery life significantly.
The balancers are compatible with all LiFePO4 batteries, lithium ion batteries, LTO batteries, and 2V/6V/12V Gel/Flooded/AGM lead acid batteries. Ideal applications include Powerwall systems, Car audio, ESS, UPS, Solar Energy, Electric Vehicles, and Solar and wind energy systems.
