Guys, I just bought a new XRS and I'm putting a 36 volt Ultrex on it. The dealer is going to put 3-group 31 AMG batteries in for it. What battery set ups are ya'll running for 36 volt trolling motors? I won't do lithium due to the fire hazard and the boat being stored in the house garage. Has anyone tried running 3 Optima D34M with the newer 36 motors? I ran this set up on my Blazer 625 and it worked great and I never ran out of juice.
