Transformer 5A 8A Battery Equalizer LiFePO4 4-24S Active Balancer
This active equalizer is a transformer push-pull rectification feedback type. The equalizing current is not a fixed size, the range is 0-10A. The size of the voltage difference determines the size of the equalizing current. There is no requirement for voltage difference and no external power supply to start, and the balance will start after the line is connected. During the equalization process, all cells are balanced synchronously, regardless of whether the cells with differential voltage are adjacent or not. Compared with common 1A equalization board, the speed of this transformer balancer is increased by 8 times.

Active Balancer 2-24S Super-Capacitor 4A BT App Li-ion / LiFePO4 / LTO
The basic principle of the active equalization technology is to use the ultra-pole capacitor as a temporary energy storage medium, charge the battery with the highest voltage to the ultra-pole capacitor, and then release the energy from the ultra-pole capacitor to the battery with the lowest voltage. The cross-flow DC-DC technology ensures that the current is constant regardless of whether the battery is charged or discharged. This product can achieve min. 1mV precision while working. It takes only two energy transfer processes to complete the equalization of the battery voltage, and the equalization efficiency is not affected by the distance between the batteries, which greatly improves the equalization efficiency.
