Replacing Exist. and Adding 2nd Battery

Hi All,
I am a new owner of a used 2010 Salem Cruise Lite Travel Trailer. I just closed it up for the winter after having winterized it. I removed the existing 12V battery and want to replace it and hopefully add a second one for those times I am Boondocking.
The current battery is a cheap EverStart Deep Cycle Marine & Rv, Group Size 24DC, 690MCA, but I doubt it is the type that shipped with it originally, so I need some suggestions:
1) What brand and/or type/model should I replace it with?
2) Should I add a 2nd battery in Parallel (not sure there is room in its location behind propane tanks)?
3) The current plastic battery box is for one battery, does anyone know where to find one that will hold two batteries?
4) The camper has a basic Tank and Battery Monitor above the sink inside but I'm curious if I should/could put an analog/digital monitor of some type outside in the battery box to show exactly what state of charge it/they are in? Will this work if I add the second battery?
5) Also, other than it being charged while towing, what is the best way to charge it/them while unhooked from the vehicle (other than running a generator)?
Thanks!

you have to decide how many times you really will be boondocking
How many days and what amount of power you need while off grid

do you have a propane fridge.... 12v fridge.
do you have to have air conditioning on 24/7 $$$ Electrical $$$
will you be camping in a new spot every day.

Traveling ... using the alternator how many hours driving between camps
OR staying in one spot ... Not traveling ........alternator charging won't apply


before you spend a bunch of $$$
use the camper a few times. decide what needs upgrading first.

add some solar
a second battery
a small generator
lithium 400ah

if you can keep your power consumption SMALL your battery and charging will be much simpler

If you are a power hog...
Plus you only have a limited amount of time to charge.
because of generator quiet times ..................... you will spend lots of $$$$$$

New trailers don't come with factory batteries, it's a dealer-installed item. That's why they are almost always the cheapest dual-purpose marine battery. Some newer trailers may have optional solar packages that may come with batteries.
1. Buy matching batteries. Most common upgrade are a pair of 6v golf cart batteries. But if you got money to burn, go LiPo.
2. Only 12v batteries should be in parallel. 6v should be in series.
3. Multiple places have dual battery boxes.
4. I'll let someone else answer that.
5. Shore power or solar.

You need to tell us what kind of camping you want to do. If you will always be hooked up to shore power, a single dual-purpose marine battery will be fine.
If you want to boondock for an extended time, then a pair of 6v golf cart batteries will be the minimum.

I had to replace my original 12 volt battery for the fall camping season. I decided to go with a pair of golf cart batteries (in series) because we boondock frequently. We are careful about electrical usage with out biggest use being the furnace. We carry a 2000 watt inverter Champion Gen to top off the batteries when needed. Solar would not work because our normal camping spot is totally shaded most of the day.
In late November we camped 5 days and only charged the batteries 2 hours a day. We ran the furnace at 50 degrees for about 8 hours a night.

For battery and box question.

One of these boxes and two - GC2 batteries.

I assume you mean 12V GC2 which is different than the 12V 24DC "deep cycle" one currently installed. The current one is 690MCA=483Ah but this doesn't really matter I'm guessing since I'm not starting an engine with it, right?
While the GC2 are Lithium Ion (LiFePO4) and probably have a much longer lifespan (more cycles) and don't leak as much, I believe they would have different connections. Not sure if anything else would have to change... Which kind were you referring to (MFG & MDL)?
The ones that I have had past experience with tend to get hot and once started a fire in the warehouse at my old job when they were being recharged.

I'm afraid you are quite confused.

GC-2 refers to a large 6-volt Flooded Lead Acid battery, originally designed for use in golf-carts, hence the designation GC-2. It is not a 12-volt battery, and it is not Lithium Ion, and it is not Lithium Iron (LiFePO4).

Could you re-phrase the questions with these thoughts in mind?

Yep, GC-2 is a 6v golf cart battery designation. It has the same basic footprint as a Group 24 12v battery but is slightly taller. Therefore requiring a GC-2 box.
And as Larry said, GC-2 is NOT a Lithium battery group.

Trailers often come with a cheap dual purpose battery .... deep cycle and cranking ability these are often called a hybrid because they are designed (the inside Plates) for a bit of everything.

TRUE deep cycle are designed with different lead plates and can store more electric stuff... makes them great for trailers / boats /pumps or solar banks
not great for starting cars ... some of them can't produce enough amps to turn over a modern high compression car.

GC2 , sometimes labeled Motive are lead acid based.
a reliable fairly cheap way to boondock ... some times boondock and a propane fridge this will get you though a few days ... add 200-400w solar panels and you can just about stay out forever.
allow the electrolyte to dry out in a flooded lead acid and it can cause fires.


But ... Lithium lifepo4
not the same as the laptop and phone batteries that spontaneously erupt in flames.... but they still can burn sometimes


They are getting cheaper and their ability to charge faster , makes them more suitable for power hungry campers.
I have 12v fridge and will go lithium soon.

if you are a handy guy and like doing stuff...
google DIY lifepo4 battery could save you a bunch of money

4) They sell battery boxes on Amazon and elsewhere that have built in battery monitors that display on the outside of the box. So, yes, you can mount a monitor on the outside of the battery box. If you connect two batteries up in parallel the voltage reading should be the same.

Only if both batteries are 12v.
If they are 6v golf cart batteries, they have be connected in series.
