Need to know Voltage of packs, Amphours. You wont be able to deplete one while charging other hooking them in parallel if they are same voltage. You might need a DC to DC converter . Inverting to AC to then use charger would be inefficient. It could work depending..............
At the "track," I want to be able to fast charge the car from an identical battery pack mounted on a small trailer. I want to be able to tow the trailer to the track, charge, race, charge, race, etc.. then charge and drive home.
Thanks for your time.
