Anyone ever consider adding an aux battery to a iMiEV to boost the range? I really like the car, and the price is pretty good, but the range is really marginal for my use. I wonder if 88 20Ah batteries with their own BMS could be added in a box behind the rear seat, hooked to the controller inputs below. The charger can only output 16 amps, so it would just take twice as long to charge (and discharge), right?
Is this feasible, or am I missing something obvious? Oh yeah - I guess a contractor to disconnect them would be a good idea.
