As a mechanical engineer with solar energy experience, converting a vehicle powered by an internal combustion engine (I.C.E.) to an electric vehicle (E.V.) necessitates the removal of the engine by a certified mechanic and the installation of the battery pack, 1 or 2 electric motors, high voltage cables, and associated instrumentation by a certified EV specialist. Depending on the available space, the EV specialist can advise you on the battery pack and electric motors. So, I recommend that you look for a qualified/certified person to do the job.
