Need battery for house and gen starting?

Popular one is ,
Trojan T-105. 225amps.
If you plan to use full hookup campgrounds all the time i would stick with a single 12v batt.

But for off grid camping two 6v’s are nice. Hook two together in series for 12v and 225 amps.

A solar panel of 200-400w would be a good way to keep the batts topped off but for very shady or rainy days the genny has to run unless you drive all day to another place, then your alternator should charge the bank. They might not charge to a complete 100% but being close to that will work.

Depending on how you plan to use your rv, a bank like this will work well if you camp in parks without hookups. You will need a small generator to run about 2-3 hrs. each day to bring the bank back up to full which is 12.6v at rest. As soon as you turn the generator off, the battery voltage will give you a higher reading of 13v plus. It will drop down to 12.6 or so as the batteries rest.

Same number through Interstate Battery

Dual 6V golf cart batteries?

Could I get a few part numbers?

Thanks!

Everstart RV batteries

IMHO, the price difference between a Marine/RV battery and the same engine starting battery is very questionable. Dual 6V golf cart batteries will start your generator and provide much more 12V power to your RV at not a lot of additional cost.

I think that’s a good suggestion as long as the battery compartment is tall enough to fit the taller 6v’s. I know i would have had to fabricate my ‘entrance step’ battery compartment to use them.

It’s just sticker shock :). I think those batts will outlast an Everlast wet cell. By the time you buy two , maybe three wet cells the price difference becomes diluted.

Quality batteries from a reputable vendor might be a better choice over the box store like Walmart. You need to check your dates to get an idea of how long those big box batteries sit on shelves.
AFAIK, wet cells don’t hold voltage as well while sitting idle compared to an AGM and possibly Si02’s. Wet cells can be depleted down to 12v ‘s approx 50% while other batteries can be depleted lower without damage.
That might be something to consider when using only a single coach battery, especially if you have to run the furnace all night. You only have so many amps available to burn.
You probably need to consider the charging time to charge back up to full charge voltage. The more expensive batteries might take less time to charge.

THANK YOU!

Grit dog,

As I said "you may not like the price".

I would not use a starter battery for the "house".

An SiO2 could be used in that manner. But you may not like the price.

Lol. At almost double the cost of LFP and 5x as much as FLA?
