I have 2 interstates (225) and 2 - 160 watt Renogy flexible solar panels on the roof.
No problems.
I have a 4,000 watt Champion duel fuel in the back of the pickup and I have been out for 10 days and not used it.

Let me preface my remarks by saying I work for Napa auto parts (for 1 more week, then I'm retired) I was considering making the switch to a pair of 6 volt batteries for a while. Doing my research, digging in the catalogs and reading the capacities, etc, I takled to several tech reps for our batteries. Most batteries made in the US are made by 1 of 2 companies, Johnson Controls (Insterstae among others) and East-Penn(Deka and others). Currently, East-Penn supplies Napa with their batteries. That said, I found out when you wire a pair of 12 volt batteries in parallel, the voltage remains the same but the amps double. When wiring a pair of 6 volt batteries in series, the voltage doubles and the amp remain the same. A single group 24 marine battery provides 75 amp hours, 130 minutes at 25 amp draw. A pair wired in parallel those number doubles. A pair of Napa 8146 six volt batteries wired in series provides 235 amps or 396 minutes at 25 amp draw. Since most our our camping is dry boon docking, the choice was easy.

Replying to Bandit12 and others. If you look at the two options I provided

4 6V Batteries at 220 Amp hours will get you 440 Total Amp hours.
4 12V Batteries at 155 Amp hours will get you a Total of 620 Amp hours.

Price is virtually identical between the two choices. So for years I have heard that 6V is superior because of the larger plates..... does that offset the higher AMP hours in this example.

The 12 volt batteries would better in this case. But, do you have the room for the longer 12 volt batteries? In a typical TT, there is not enough room for 2 of those 12volt batteries. Myself, I’m not a 6 volt guy, but they will fit into 2 group 24 battery boxes that will fit on the tounge of a TT. Jay

I have 12 V now in the Seneca, these will fit.

You dont mention your Seneca year but the GC2 6 volts batteries should fit fine. In our 2018.5 I had four Trojan 105's to start with and now I have six Lifeline 6 volts in it.

FYI, Johnson Controls has recently (last May) sold off it's battery division to Brookfield Business Partners.

Yes, you sent me those pix before. I have a 2014 with the house batteries on their own separate tray. I think I agree that the 4 12v AGM with 155 Amp-hours each is my best value and I don't have to change anything in the rig. I have cheap Costco 12v batteries now and am getting by. When those are done this will double my AMP hours and provide me with maintenance-free batteries.
