First off, please excuse me if this question has already been answered elsewhere. I have looked but couldn't find quite the answer I was looking for so....
In case you don't know, I'm currently building a 44", scale, traditional sailing trawler with auxiliary motor. I'm wondering what type of battery would be best employed.
I've got Action Man's electrickery to drive it all but require a 12v source. Due to the design/layout of the boat, two separate batteries/packs would be required - a la saddle tank. I would like to get a reasonable running time out of it as I might want to motor around some days and I've also got three Hitec sail winches (drum type) to power. The motor is a geared 500 (again from Action).
So, do I go lead acid or NIMH (or other)?
Am I best with two 12v batteries in parallel or two 6v batteries in series?
I half expect the answer to be "whatever takes your fancy mate" but just thought there might be differences. Reliability etc.
Cheers!
Robert.
