SolarKing SK-CB4S Cell Balancer

SKU: 6451

SolarKing lithium battery cells balancers are used when you place lithium battery cells in series and want to keep each cell at a similar voltage to each other. When battery cells are placed in series with no balancer it is possible that a cell can become the only cell being charged or the only cell that is flat and not being charged. Your charger is not actually able to monitor the charge state of each cell so the cell balancer does this for you.

Battery Cell balancers can discharge an over charged cell to bring it back to the same level as the other cells by diverting this extra power into the undercharged cells.

You can use multiple battery balancers connected together to meet the amount of cells you have.
