Working conditions: When the voltage difference between adjacent batteries is greater than 0.1V (very important), the balance is automatically turned on until the voltage difference is about 0.03V and the balance ends. Due to the obvious voltage jump in the floating charge and over-discharge phases of the battery voltage difference, the balance will work to the maximum at this stage, and the effect will be more obvious after several cycles The balanced design is 1.5A, and the actual test is up to 1.2A. It can be packed into the battery, and the extremely low consumption can be ignored. Special attention: This product is an active equalization board, not a protection board, and professionally handles the problems caused by differential pressure 1. The active equalization board cannot be used in place of the protection board 2. The active equalization board cannot be used for daily debugging. It can only be used together with the protection board to be fixed and packaged. Different batches, product appearance and color may be different, does not affect the use Colour: random color , don't accept the specified color Material:PCB Package Contents: 1 x Active Balance Board 1 x Cable 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.
