Wire in 2nd battery?

I have a 22' NorthTrail that only has 1 battery. We do a lot of boon-docking & are wondering if wiring in a 2nd battery would help with boosting power. Any help appreciated.

If a second battery would fit, you can double you capacity. If you stick with lead acid batteries, you can gain even more with two six volt batteries wired in series. Then there are the Lithium batteries. They do require your charger to be compatible with lithium technology. Do pay attention to the length, width, and height of the batteries to fix your battery box.

Not entirely sure if you have the room on a 22' north trail. I have 3 batteries on my 32' North trail. I used a different box and put them all in parallel. I also used group 29/31 sized batteries that also improved the battery storage. I can run the furnace for a couple of days in cool weather with this setup and have added solar to charge this large battery pack. I rarely have the converter turned on to charge the batteries as I use the solar panels most of the time.

I repainted the box to a close match to my NT.

If you are running low on battery during the night. You need more battery. If your running low over a couple of days. You might want to concider a small generator
if your looking for more battery capacity. Looking at the lithium or even the AGM batteries might be enough. My flooded batteries I don’t like to discharge more than 80% because that drastically effects the life span. AGM batteries allow for more discharge and faster charge rates while saving a little weight. I haven’t studied the lithium technology. But I understand they hold their voltage and can handle a very low discharge before recharging. And they are light weight.
