2) Series battery connection: When using multiple batteries in series, all batteries must equal in voltage
and amp hour capacity, and the sum of their voltages must be equal to the voltage of unit's nominal input
voltage.
3) Parallel battery connection: When using multiple batteries in parallel, each battery's voltage must be
equal to the voltage of unit's nominal input voltage.

To get more charge current, the Battery Charger can be connected in parallel configuration. Maximum of
two units can be connected in parallel. For example, in 12Vdc mode, connecting 2 Battery Chargers in
parallel can get maximal 150Amp charging current. In 24Vdc mode, the paralleled system can reach
maximal 75Amp current.
