The four 45A batteries are 180AH, that is,180×12 = 2160 wh, 2 160×80%= 1728WH,/kloc-0. .

0.864×60=5 1.84 minutes (perfect battery, actually slightly less than this value).

The inverter current of 2000 watts is greater than the current of 166.7A, and the battery is particularly easy to break down, which is not worth the loss. It is recommended to pull 22 volts AC nearby! I hope I can help you. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
