6CT Battery Upgrade
First off, this is a 2009 Standard Length Lounge and thanks to Lew for the advice!
I almost finished with a Magnum MMS1012 install along with the RC50 remote and BMK battery monitor module. One of the reasons for all this was the addition of 2-Lifeline 6CT batteries. In addition, I upgraded all the cables to 1/0 gauge welding wire and added the Progressive surge protector.
The batteries are stacked and because the terminals are just at the height of the metal lid, I drilled 2-4" holes and installed 2-schedule 40 knock out caps with silicone so I wouldn't have to worry about them shorting out on the lid.
