Even if you use their specified values, the Peukert exponent is still something like 1.2, which is not very good for an AGM battery.
Now I recall that you wanted a battery to support a high load with minimal voltage drop. For that you want a battery with a Peukert as close to 1.0 as possible. The best option (besides LiFePO4) for this would be a 'dual purpose' AGM, something like an Odyssey PC-2150. This would give you over an hour 65A with Peukert exponent around 1.08.
oh man but odyssey batterys cost way way to much, they make SiO2 looks like a bargin, and realy they arnt that great for rv's.

Crazy thing is, Odyssey is cheaper than the SiO2 he ended up with. Agree that they are not ideal for 'normal' RV use but for the specific application BFL had (short, large loads) they are ideal.
