Sell 4s LiFePO4 capacitive active cell balancer energy transfer board. best price

Balancer protects the battery system from damage, predicts and increases battery life, and maintains the battery system in an accurate and reliable operational condition. Battery pack cells Imbalance is a vital matter in the battery system life. Without the balancing system, the individual cells voltages will drift apart over time. The capacity of the total battery pack will also decrease more quickly during operation then fail the battery system. When the battery error voltage is above 0.1V, the balance work is started until the error is stopped at 30mv. The built-in improved ultra-low internal resistance MOS, the balance current is 0-5A, and the battery voltage difference is smaller. Applicable to Li-ion ion and LiFePO4 cell. Working voltage: 2.0V-4.2V When the balance indicator is on, the balance work is turned on. The balance indicator goes out, the balance circuit sleeps, The balance indicator flashes, it drop cells, or the circuit is faulty. Please connect the lead wires in correct order from B- to B4/B+ to avoid damaged to capacitors. Double check the sequence.
