I built a stretch cruiser ebike out of parts, including a bafang / 8fun mid drive and 52v “shark” style battery. It does pedal assist and straight up throttle to danger in lickety-split. This is a cool project, however, I wouldn’t have gone this route because: It isn’t a great idea to lock up an ebike, but there are circumstances where you might want to and you’ll want to take the battery with you when you do. If you need added capacity, I’d recommend a second battery to swap in during a longer ride. This can limit the size of the extreme failure should that occur, and let’s you choose less weight for shorter trips. Finally, there are some quality battery builds out there, in a variety of shapes that include enclosures offering some resistance to shock. Besides all the testing and perfect wiring here, you can rely somewhat on the seller to back up their work.
