Not sure what the charge rate might be, but a light, portable 1000-2000w generator on the tail of an electric buggy might be enough contingency. Without any offense meant, I assume we’re not talking about taking your wheelchair out 10miles backcountry off of the nearest road in extreme terrain, but rather a more typical midwestern style hunt where you drive part way out to a blind or stand and roll the rest of the way in your chair.

I know a few older guys who drive their gas powered UTV out to the field, park, flip down some camo covers, and hunt from the UTV as if it were a blind. They aren’t bowhunting, mind you, but they do take deer every year.

Personally, if the performance specs were identical, I’d take electric over gas, then throw a battery meter onboard so I could tell if it were low, maybe a solar trickle charger on the roof, and a small portable gas powered generator on board. Not many guys have a spare tire on their UTV’s, or even a plug kit, so let’s really be honest about how well prepared for realistic in-field-failures guys really are.
