Adding 2nd battery

We have on the 244rbs, we are using 2 off 110AH 12V AGM. Mounted under the seats over the axles.
Seemed a sensible place, heavy stuff over the axles.

We also carry another 2 batteries the same in the Jeep feed by 400 watt solar panels on the travel trailers roof.
 
The battery tray is likely not wide enough for 2 batteries so you'll need to have it modified. Will require a bit a welding but its pretty easy for anyone with welding skills.

After that you need to decide if you want to go with 12V or 6V. The 6V will last longer before needing a recharge. There's several threads where people have done this.
 
2 on the tongue

I bolted a battery tray to the tongue, behind the propane bottles. I used U-bolts over the frame. I then bolted two battery boxes to the tray. Welding would have been better than bolts, but I do not know how to weld.
 
It's pretty easy depending on what you want it to do. For most of us, wiring them such as this is the easiest.
Car audio guys always install fuses, but I don't think we need to. Just make sure your connector cables are big enough.
