Use a 4.8 or 6 volt battery pack. The ignition can handle the
higher peak voltage of these packs when fully charged.
Higher voltage packs (Lithium, etc) can be used, but require
a regulator. We recommend a regulator with a 5.5 or 6 volt
output. Excessive voltage will damage the ignition system
and will void the warranty.
