Cannonball LION Battery Boxes

Our electric start system just got even more stealthy.

The Cannonball Stealth Starter can give classic Harley Big Twins (with rigid or swingarm frames) the almost invisible option of starting by pushing a button. For reliable operation this system needs a powerful 12V Li-Ion battery, a solenoid, additional wiring and circuit breakers. To avoid an unsightly mess we developed this solution that incorporates everything inside a humble looking Harley HM5 battery case. From the outside it’s as stock looking as the 6V original, but the electrics inside are state of the art. In the two compartments there’s room for a 12 cell Antigravity Li-Ion battery and all necessary electrical components. A stock like lid looks as innocent as the vintage acid lead battery it replaces.
