Rob, I was assuming James knew 8D was sufficient capacity for him.

1 8D weighs about 130LBS and has about 240AH @ 12 Volt

2 group 31’s in parallel weigh 120 lbs together and have about 210AH @ 12 Volt

Or two – 6 Volt Golf cart batteries in series together weigh 125 lbs and have 230AH @ 12 Volt

Doing some Tony style math, you get about 1.75 Ah per pound @12 volts. or a bit over 20 wh/lb

Sizing a bank for loads is a whole other discussion. Hehe. But might be one worth having.
