7.5’ ramps, it is pretty steep. It can be done, but not easy. Much better to find berm and put ramp on that, which lessens the angle. A lighter bike would be easier to maneuver.
I believe Kyle from Out of Spec said those are just V4 dispensers, the actually chargers are still v3, so he called them V3.5. Not that the lightning can take the increased power anyway. The longer cords are welcome.
