The Romi chassis has multiple options for configuring the batteries. The battery compartment is separated into two sections: a four-battery section and a two-battery section. Either section of the battery compartment can be used independently, shown in the diagram below with nominal NiMH voltages and a common ground: | The Romi chassis has multiple options for configuring the batteries.
