Batteries are interconnected to increase the battery voltage or to increase the battery capacity or both. Multiple interconnected batteries are called a battery bank. When batteries are connected in series, the voltage increases. When batteries are connected in parallel, the capacity increases.
It measures the battery bank voltage and also the individual battery voltages. The battery balancer activates as soon as the battery bank is being charged and the charge voltage has reached more than 27.3V. At that moment, the battery balancer will start to measure and compare the voltages of both batteries.
