Looking to add a second battery

[AC4life]

Hey there, I'm looking for advice on adding a second battery to my 2014 32TSBH. It has the single battery that it came with the trailer from the dealership but I would like to add a second battery in series with this one. We have a seasonal campsite that has no power hookup so we run a generator to charge batteries and for other use but I would like to extend the amount of time I can run lights ect. off battery power. Does anyone have any advice on what brand, type of battery to buy? Tips on hooking up batteries in series? Any advice or tips would be greatly appreciated. Thanks and happy camping

I have had good luck with the Interstate batteries that Costco sells. Very reasonable price.
I would take the batteries home with you and set them up on a slow charge when your not at the camp site.
You should get 2-3 days on them B-4 you need to re-charge

My first choice would be 2 Trojan t105 6 volt batteries in series. My second choice would be a second 12 volt battery in parallel. Maintenance free batteries would also be a good choice because most of the time I forget to check the water level. Deep cycle is a must. The mfg. is a personal thing, they all do the job.

DON'T ADD A SECOND 12VOLT BATTERY IN SERIES! That gives you 24 volts!

To gain amp hours, add 12 volt batteries in parallel.

There's a whole bunch of other stuff to consider. As a start, having matched batteries - purchased at the same time; not adding a new 12v battery to your current old 12v one.

Does your battery supply all the power you need over night?
Does your generator fully charge your single battery each day?

Whatever you draw out of the battery/batteries has to be put back into the batteries with your generator. Adding a battery capacity may let you go two days between charging, but you'll have to fully charge both batteries by running the generator twice as long.

Yes I will be hooking the batteries up in parallel not in series. I am looking for equal power but for greater length of time. Thanks for the help!! Can't wait to fly home from work and get back to the lake where I belong lol
