Made 13 passes Saturday with a single Group 31 in the trunk, 105amp GM alternator supplying the juice, never had my charger out. Doubt there are many cars using as much power as mine:

Dual stock GM F-Body fans, over 20 amps each.
Mezier electric water pump.
Weldon EFI fuel pump.
8 injectors, though they take very little.
4 coil packs (DIS waste fire setup, like a GN).
The last two hours ran the electric fan on the 2nd trans cooler, not sure what it draws.

The last 6 passes were made 15 minutes between each, only got to the trailer for fuel.

So....... Why mess with these little batteries you have to worry about charging when there are massive batteries out there that will never give you an issue?
