Generator or batteries for boondocking?

[belfert]

I could put in LifePO4 batteries that would have slightly more amp hours than my AGM batteries for around $2,500.  I would have more usable amp hours since LifePO4 batteries can be discharged much further without damage.  I have enough space that I could put in even more LifePO4 batteries for double the amp hours of my AGM batteries, but it would cost me around $5,000.

I can buy a lot of generator fuel for $2,500.

Sounds like you came to the same outcome as a few already posted earlier. Run the Genny , just doesn't make sense to invest anything more then just running the generator imo based on your planned yearly use. I mean have new batteries  these just sitting around for 11 months each year for once a year trip?  Even buying a replacement Lead acid bank doesn't really make any sense being you have a genny already to handle your one time use yearly trip already. Best hope your Genny doesn't fail due to prolong yearly sitting , other then that just use what you have already.

Actually with the LifePO4 batteries you have double the usable power as you are not supposed to discharge AGM batteries below 50%.

There are many finer points about lithium that one just has to believe or spend the time researching and learning the principles of nominal vs full capacity, DOD, SOC, C charge and discharge rates, continuous vs peak discharge, chemistry, effects of DOD on charge cycles, etc. That is just the raw cells. then there are all the factors such as BMS functions, cell balancing, wiring, chargers, etc. Some here go on about operating in cold but get way off track on a trivial consideration as it takes practically zero engineering to have a battery box keep batteries in operating range. All these other factors are what matters a lot more. The other one that really is a waste of time trying to convey is the difference in charging for lithium vs lead batteries.

Those of us that have taken the time to research, learn, and apply understand the vast benefits. I'm getting close to not bother replying except to those who post specific questions that show the basics are understood and need help sorting out options or tradeoffs etc.
To be fair, this a forum for BUS topics and the nitty gritty of lithium storage and solar power really need to  be done in their appropriate forums, not here.

Lol I thought you were writing a article for BCM to publish to help us just kidding.I know I will need to do a lot of research on solar and storage since we bought 173 acres in Globe where the summers are milder than here.Power is about a mile away and ARP wants $185,000.00 to run the power to the land so solar and batteries here I come we are going to be off grid I think they call that

Good memory. I did inquire about writing about DIY lithium battery project, then decided to wait for a couple reasons. Article would carry a lot more value if presented after some time in service. With over a year, that is now met. The other major aspect, at least for me, was the off grid system which includes solar panels. So, now with a year of solar feeding the battery system, there is no excuses. LOL I'll follow up with Gary as it is time to get that submitted. thanks

Good deal I do better reading black and white,I did some searching last night on utube and google.Utube is boring to me everyone has a different opinion and to wrapped in their self. With google this morning I have about 100 ads people trying to sell solar and batteries lol some offering free solar, that is going to happen nothing is free in this world

Who is buying 173 acres? Windy or Clifford cant tell the way that reads?

[windtrader]

not me. i own 5000 acres with a few other owners. Staging area for the retreat when the collapse comes.

Rick and I bought the 173 acres in Globe at the foot of the Pina Mountains and Tonto National Forest flat with good water and plenty of pine trees @ 5400 ft elevation,I'll send you some photos

Oh no another Coast to Coast listener. A friend of ours keeps talking about all this, LOL

Do people really listen to him  tuning the radio one time he was on,in about 10 seconds I found another station

He who laughs last laughs best. And can laugh at all! Cheap insurance and sure nice to know you got a place to go where you have rights of access. Not getting political but the way the public is losing their minds and forcing less laws being enforced and the increase of crime, my view is this persistent trend leads to less personal safety. Who knows where it ends up, people wake up or ignore it all until it snaps and too late. My view is one of taking care of others, family and close friends who would benefit from living in a safe haven while it gets sorted out. Just like insurance, you don't need it until you do, then it's too late.

In Hornbrook?

Ya Don is that it Hornbrook, LOL In the State of Jefferson, Hummmmmm
