John has a long history of engineering and building, I am guessing he also means don't cover any roots of a big tree, many are underground but huge. Please be careful with placement, possible to build farther away from tree? And have no worries about roots whatsoever

Larry you brought up another question
If I weekly or monthly charge to full capacity, to equalize or balance the cells, is that ok? Do I need to switch to BMS that is active, even though this is not a complex , whole house system?  Your opinion will help me, thanks

Dang Larry, I was just wondering about your take on things.  You always have knowledge that comes from real life work.  

Sounds like custom battery building is in my future, that sounds like the true path. But I'm preparing for an odd project , far from home, it is work but also a bit of adventure
Used my smart charger yesterday and it specifies  THE CC CV method when LFP is the battery.  It is pumping out 14.6V when set for LFP, and it can be adjusted for LA or AGM as well. I think I am in good shape. Thanks for the reply

One question popped up yesterday, could I use a 450 watt 12v solar panel for the charging of my all in one unit, instead of 100w at 12v? One electrician told me that was possible but he is new to diy solar installation

You might try the sand filter with some limestone gravel mixed in.  Here in N GA all gravel is normally granite, but in areas with karst topography ....think caves systems and sinkholes... I am pretty sure a truckload of gravel will be limestone. Best of luck in your quest
Oh, a friend just told me try using gypsum in the same way.  But I don't believe using old sheetrock would be so great

I built one with cedar boards milled by my grandpa,  using a small woodstove from his old greenhouse.  It held up to 4 folks.    It was great, but don't end up like my buddy Dan....he was a bit light headed and inadvertently self-administered a second degree burn on his nether regions.  Ouch.  
And to think, most people believe Free Willy is a kids movie

Breath of fall on this fine Sabbath, our  UGA Bulldogs won a rough game in overtime and the sunny  yet cool uplands are beckoning.  My new  low amp charger is doing a great job, drawing fewer watts than I guessed. Many ways to adjust for different charging scenarios.

Thanks for corrections and comments,  will leave town in a few days, please know I will carefully apply my newfound skills, ciao, rico

"It lists a charge voltage of 14.6 volts. It seems to be made as a direct drop in for an automative battery. I believe you should be good with a charger that you can adjust to 14.6 volts"  David, thanks for the opinions.

Ok, I thought auto batteries are high on cranking amps, never thought of 100A as ideal for starting a car.  Not to worry though, this is my GA dry run, I will buy equivalent battery new  near the project, it is over 2000 miles away, that is what I am trying to reiterate,  really remote.  

From my post yesterday:
"Since the LFP battery is small, only 245wH , i desire keeping another battery set to charge during daylight hours"
That is my 12v external LFP, with quadruple the power in storage.  I can charge it during peak daylight hours. (From the Ecoflow&&&&&)
The house gets 300 sunny days per year and rarely drops below 2 C in winter. When I am using tools and lights at 3 am, for example, I would potentially need to use this BACKUP battery feeding juice to my ecoflow unit via DC charge port.  I have the approved cables.  No, I never envisioned any other way to use the external LFP"

I am glad you agree that I only feed the external battery from an AC source. And like i pointed out, i will feed DC power back to the Ecoflow when needed  its 1024Wh feeding the internal battery which is 245Wh.  But I won't be working down the lane from my house.  This is why I am testing everything at home, in advance of my journey.  Today external fed the internal battery smoothly and efficiently

Thank you kindly Eric,  your voice is always a welcome sound, for off grid and many other topics

Thanks for your patience and attention to detail, I did post the wrong charger, I intended to use same company but 7A version.  I will not get close to the 300w limit while charging.  

And forgive me , looking back at my posts this is not a great explanation

To reiterate,  this is for a restoration project on a1930 house, secluded and without power.  For my purposes this plan works better than having a temp pole installed by the local power company.  I need to go with a bare bones setup.  This plan seems the most economical and efficient,  in these circumstances.
