This means that it will spill if you wreck, and you don't want to take a bath in battery acid. I linked the best, because they are the best. Longer run time, and will last far longer than a cheaper battery.
For reference, I run a trolling motor with a 40 amp draw for about 2.5 hours on a single Walmart battery.

gotcha that all makes since, thanks a ton!

Now for the motor controller......would you happen to know my options on that?
