Sure, if you have room for battery with a 2+ foot dimension. Here's a
deal - buy 6 to get 12 volts -

pounds to your bus.

East Penn Deka ( http://www.eastpenn-deka.com/ )makes flooded, AGM and
Gel batteries in "automotive" sizes. They don't even bother to rate the
flooded batteries beyond 60% discharge where they're rated at 700
cycles. They say that 80%/600 for gel and 80%/200 for AGM is typical.
Since they make and sell all three types, I tend to trust their
relative figures.

Here's how they rate the relative performance of their batteries for RV
use: http://www.eastpenn-deka.com/assets/base/1081.pdf
