Goal

Design and Build a new tractive battery for the goldwing conversion

Requirements

Drop-in replacemen tractive battery for use on the goldwing conversion. Higher capacity and dischcharge capability as an upgrade.

Result / Current Incarnation

The tractive battery pack is complete and functional, but not integrated into any vehicle.
The resulting assembly is slightly too large to fit in the motorcycle without modifying the bike frame, and the additional range was not needed.
