Your 30 amp's is equilivant to 1 amp hour drain.

Buggger. That's what happens when you can't get the words out quick enough.

3A x 10 hours per night x 3 nights = 90AH
I've been using this smilie a lot lately.

I also just thought of the one thing that I forgot that will make it nearly impossible to get a big enough battery to do all three nights. Temperature.

The average temp overnight where the camp site is will determine the amount of charge the battery has. For every degree below 25C the battery capacity (for SLA or Wet) drops 1%. So at 10C the battery only stores 85% of it's rating.

I'll have to go back to the drawing board I think
