The deep cycle battery is getting old. Since I tend to use my 12 volt trolling motor a lot, is it wise to get 2 New deep cycle batteries and wire them in parallel. According to an article in Great Lakes Angler this would keep the voltage the same at 12 volts, but it would double the amp capacity. I would imagine that I would get a 2 bank battery charger. The main advantage I figure is a longer run time without upgrading to a more powerful trolling motor and a 24 volt system. Has anyone actually done this? Is it wise? Are there any unforseen problems or issues with this setup? Any input would be appreciated.
