My main problem is I live in a highrise so I cannot plugin but you know I was thinking about gas cans and sorta wondering if someone makes a hoofable battery setup that would be equivalent. Im wondering if just those ones for camping might work. So figure a five gallon gas can will get you 100 miles. I feel a battery that could handle that distance would be huge though. Thing is you could charge it overnight in the unit and then bring it down in the morning. Not sure how long it would take to do the battery to battery though. Would sorta solve that if it was a affordable enough add on you had to get.
Early on this was talked about with evs and it would be like a robotic system to swap them out but I think there was to many complications. I can see why it would work with smaller vehicles being human swapable.
