| With today's 12" -3 total electronics units draining from the starting battery, I have wired direct to battery. Strongest battery available , has anyone tried having 2 starting batteries with your electronics and starter ? Have 4 batteries already, 1 starting - 3 trolling. If so with great results please tell me how or why not. Thank YOU |

| I used to have issues till I got a size 31 batteries plus x2, it's amazing. But yes if you have room for another battery that is not uncommon |

…muskie guys are running 5 batteries too! IMHO, 2 group 31 deep cycle batteries are going to be mandatory if you're running 3-12” screens. I'm on my second boat with that type configuration, and before that was running 3-10” screens on 2 group 31s.
Further; it's pretty common to have a battery isolator so the electronics/live well/ect cannot discharge the primary starting battery these days. However, I've been running the 2 house (starting) batteries hooked-up in series with only a few minor issues without an isolator, so I have just stayed with that configuration.
In 2017 I had a pesky intermittent electronics brownout when I would start my big motor, and although a battery isolator may have helped to solve the problem, my remedy was to simply not shut off the kicker motor until after I started the big motor… and then just replaced the entire boat at the end of the year.
I went a little overboard with heavier wires etc. while rigging the electronics in the new boat in the winter of 2017/8, and it performed almost flawlessly.
