RV Battery

I need a couple of new batteries for my RV, guess I will have to go with 6v golf carts (Sams club) due to the high cost of everything else.

$900 for a battery..... what's in it, gold?

What $900 battery are you referring to? Lithium ?

Golf cart batteries are probably the most popular replacement combination for people on limited budgets or who are not OCCC challenged. More bang for the buck, for sure, but they're heavy.
As someone who is OCCC challenged, I installed 2 100Ah Relions last October, with a toal weight of around 60lbs - they replaced 2 FLA NAPA OEMs that weighed in at around 90lbs. Hadn't tested them in the real world until last week. Just got back from a week out, mostly off grid to test them. They performed flawlessly and are more or less a "set it, and forget it" option, for me, at least. They are pricey, but in my case, they're worth it.

I swapped the 2 NAPA flooded batteries for Battle Borns for a few reasons...
1/3 the weight
More usable amp hours
Much faster recharging
No messing with distilled water, or acid fumes.

Me too. Went lithium a few years ago. Big up-front cost but worth every penny. And lithium batteries make much better use of solar in case that's in your future.

The projected life of my lithium batteries is about 10 years beyond my actuarial life expectancy.

Solar + wind??

A couple interesting items on solar. I would like to go to it after my lead acid batteries give up (PS, am using a 200 watt portable solar panel when go camping to help charge).
This is an article read a couple days ago on cobalt in lithium batteries,
https://www.reuters.com/article/us-t...-idUSKBN20C0RP.
Also I learned a lot from this guy and his info. My brother really researches stuff out and he told me about this guy. Is pretty good info if trying to figure things out.
I was also starting to look at some type of wind generator (just a small one) for those times when its overcast and not much sun. Has anyone set up a small portable wind generator also?
Thank you for your time, Kasey

Campskunk had a wind turbine as part of his off grid setup 7 years ago.
Link to story with a very small pic of it. There may be better pics of it out there, but it was so long ago, I can't recqll where they might be.
https://community.fmca.com/blogs/ent...pskunks-story/

I'm not sure what the story about the cobalt use in EV batteries has to do with using Lithium Iron Phosphate batteries as coach batteries, unless it's to point out how much farther we amateur electricians and campers are ahead of Darth Elon and his evil Tesla Empire?

They're probably the most popular option for replacement house batteries, based on comments on the various forums, if you can carry the weight. With the money you'll save from their resilience and longevity, you can try LiFePO4 next time out. In about 10 years, if you're lucky.

As of a month ago, you can build your own 100aH lithium battery for about half the price of a Battleborn.

https://youtu.be/i4oJYhGKw1s


This comes from Will Prowse's channel. He has other DIY options that are on the less expensive side besides this one. This one seems to be the best deal so far for lithium. Rest assured he will continue to come out with other good moderately priced DIY options.

DIY is not for everyone. There are drawbacks vs buying namebrand batteries with warranties. Reliability will still be an unknown even though Will tries very hard to test everything he gets.

To me, going the DIY route is fun, educational, and cost efficient at basically a "buy one get one free" compared to purchasing one from a store.

If you are willing to take the calculated risks to save some good $$, this may be a good option.
