IMO, the battery is likely to be located where the current engine resides. That would allow the existing frame to provide plenty of protection. However I'm curious to see how well a Li-Ion can stand up to the rigors of off-roading or rock climbing.Biggest fear would be reinforcing the plate protecting the battery. Not sure what would happen if that made sudden contact with a large rock. Know of one Tesla that caught fire. Don't recall why but thought it was some rupture from contact.
