I was told never to use the gel batteries with outboard motors. Something to do with the charging system off the motors coukld cause the batteries to explode. No real proof, just what a buddy told me.

In the past I always ran a type 27 Marine Deep Cycle, but found they just didn't cut the mustard for what I was running off them. Now I am running 2 6 volt industrial deep cylce batteries in line. They are much smaller, produce more power, and I have had zero problems.

I agree it is nice to be able to mount your batteries wherever you want. (i.e. beaing able to mount gel batteries upside down) but my question is, where in a boat do you mount a battery upside down, and if you had a spot how would you get it to stay up there???
