BatteryPowered

A [container] that [provides power] to other components via inserted batteries and can expose a physical connector

You can use the following options with this component:
name <name> - sets the name of the component
desc <desc> - sets the description of the component
type <type> - sets the battery type, e.g. AAA
number <amount> - how many batteries it can hold
preposition <prep> - overrides the 'in' container preposition
transparent - toggles whether you can see contents when closed
series - toggles whether the batteries are treated as in series or in parallel
charge <watts> - sets the maximum rate the batteries can recharge at when connected to power
connection add <gender> <type> <powered> - adds a connection type
connection remove <gender> <type> - removes a connection type.

Note:

In series batteries would be used for something needing a higher voltage, but drains the batteries faster.
In parallel batteries split the drain amongst themselves so drain slower
