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

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

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