How to Use:
For a battery pack with a particularly large capacity (100Ah‑300Ah), it is evident that the equalization time will be longer.

Package List:
1 x Capacitor Active Balance Board

Note:
Note 1: Before wiring or connecting the plug, the switch must be turned OFF first! !
After confirming that the wiring sequence is correct, turn the switch to the ON position and start working. 0V is the total negative electrode of the battery pack. Start wiring from 0V in order. If you connect the wrong wire, it will burn the board!
Note 2: Use a copper wire of 0.3 mm² or more for connection, the thicker the cable, the better, and the shorter the better. (18AGW, 20AWG, 22AWG recommended)
Note 3: When working with high current, a slight noise is normal. After connecting the battery for the first time or shutting down for a long time, the startup is slow, please wait patiently. When the switch is turned OFF, the indicator light will not go out immediately because the capacitor has residual power.
Note 4: For the 4S version, when used for a 3 string battery pack, the fourth section can be made up with idle small capacity old batteries, otherwise it will be difficult to start or easy to break.
