Recently, our German customer ordered 50 pieces of 4S battery balancers from us. The customer needed FedEx delivery, so we prepared the goods as soon as possible and arranged the shipment via FedEx.

Before balancing, the voltage of each cell is different. As a result, some cells cannot be fully charged, and the full capacity cannot be utilized during discharge. After using the battery balancer, each cell can be charged equally, all cells can discharge evenly, and the full capacity of the pack can be utilized.
If you have any requirements, please feel free to contact us.
