THis is actually for a sprinter van but the kids on those forums are sometime difficult and un-civil
An 8000 BTU window AC unit will be split in two so the condenser is outside the vehicle (very cool idea from a van guy)
AC draws 800 watts - that's 66 amps at 12V (round up to 70 amps for the inverter)
Duracell GC2 6V battery will provide 75 amps for 120 min.
All flooded battery numbers are cut in half for real world usage so two of these batteries in series for 12V should provide 75 amps for one hour, right?
But the 25 amp discharge rate is 448 minutes so if I half that (224 min) I can get almost four hours with three pairs of batteries.
Do i have this right?

It's gonna take a lot of Adderall to get this thing right.
