4s-8s 5A Active Balance Capacitor Energy Transfer, Universal -ion Lifepo4 batteries, Can withstand 5A current equalization, equalization accuracy within 0.005V The equalizing current is determined by the voltage drop. The greater the voltage drop, the greater the current. In addition, it is also related to the internal resistance of the battery and the internal resistance of the wiring. The relationship is Ohm's law. Because it is the global active balancing of capacitors. The voltage balancing accuracy is millivolt level. It is not a high-precision meter, but there is no difference. The hardware can theoretically have no voltage difference. It is just a matter of time. Support 4s to 8S battery packs After the circuit board is connected, it is always balanced globally. For unbalanced battery packs, a certain capacity can be restored. The theoretical recovery capacity can reach the actual capacity of the battery. There is a separate switch to start and close the balance Matters needing attention!!!! This circuit board only has the equalization function. There is no overcharge and overdischarge function. The wiring should strictly correspond to the wiring on the board. Touch to turn on equalization after power on When the battery voltage is low, the touch switch will automatically turn off Accidental battery short circuit accident. Touch switch will also automatically turn off SIZE : 5x10cm Color: Material: PC+ metal Package Contents: 1 x Battery Equalizer Energy Transfer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
