R&D at Tesla, is projecting $100 per KWH battery packs by next year, which will be perfect for off grid homestead power!
Tesla is very busy improving energy density, and by so doing, reducing overall costs for batteries. I have approached this cost by recovering batteries from dead lap top battery packs, and building my own 24 volt battery banks.

Article on density and cost improvements:
https://cleantechnica.com/2018/06/09/100-kwh-tesla-battery-cells-this-year-100-kwh-tesla-battery-packs-in-2020/

Their focus, as it should be; is cost reduction of batteries for automotive use. The spin off benefit is that as batteries become a more effective fuel source, they also will be more cost effective for fixed location (off grid) power uses. Homesteaders need to watch Tesla, and replace lead acid batteries before they wear out; with long life high power batteries!

>“We think at the cell level probably we can do better than $100/kWh maybe later this year … depending upon [stable] commodity prices…. [W]ith further improvements to the cell chemistry, the production process, and more vertical integration on the cell side, for example, integrating the production of cathode and anode materials at the Gigafactory, and improved design of the module and pack, we think long-term we can get below $100/kWh at the pack level. Which is really the key figure of merit for a car. But long-term meaning definitely less than 2 years.”

This will rock the fixed power world too, so be ready!

>Given that Elon Musk said that in 2 years time (2020) the battery pack cost per kWh will likely achieve the cost point that the cell cost will achieve later this year (2018) — and estimating that the pack adds around 30% to the cost — we can see that Tesla remains on an approximate 15% per year cost reduction curve. Going forward, if it can maintain this trajectory (and there is every indication that it can and is determined to), Tesla will pass pack-level costs of $90/kWh in 2021, and $60/kWh in 2023.

I have a good Friend in Florida running his house off of a 5kw Tesla Car battery. He wants to add another to add AC to his Off grid house. This might be his next battery upgrade. 

We need to watch, especially those who have lead acid batteries; for cost effective replacements as the old battery types as they sulfide and begin to fail. The biggest advantage is that you will not have to have any special expertise with battery management systems to use a factory battery pack. You will still gain the long life expectancy of the LiIon battery technology. 

Technology keeps giving us more options, and we need to keep our eyes open, to make use of them to our best advantage.

That's great news I'd they get that cost way down.

I plan to start wirh 24,000 watts of 24 volt batteries to power my house. 

This would be a livable cost to buy all new....

Awesome news. I've been looking into options for a little while now...Seems like things might be progressing in the right direction.

I have been recovering good cells from exhausted laptop batteries for a couple of years. Each cell is about 10 watts at a sustainable rate of discharge, and I will stack six initially to make a 24 volt 60 watt battery. I will parallel eight of these in an assembly for a 480 watt battery. I have enough salvaged for 19 of these assemblies so far with a couple of more assemblies worth. still untested.

That said, I would LOVE to get my hands on some of these to add to my current battery bank! I want 24kw of battery storage for my off grid system to start with.

If I don't have enough battery storage by the time to move, I will buy some lead acid to fill in while I salvage more LiIon cells. Then I can slowly change them out, and move the lead acid into my greenhouse to use them up there. Life is NOT boring, keep on homesteading, LOL!

Sounds like you've got it worked out pretty well. I'm nowhere near as advanced, or skilled, in this area. I have a solar array but no storage just yet. My wife't uncle and aunt live completely off-grid though and they have a huge battery bank, lead acid.

They live on the beach so harvest from the sea and grow a few things in pots but barter and trade seafood for other things. They supplement from the store of course, but overall manage to be reasonably self-sufficent depending on the season. We go up there (4.5 hours away) a few times a year and it's pretty cool to see the set up. 

I am probably moving in a few years and will  set up a storage system for power at that property for sure...So, I hope the tech gets cheaper and better! 😊

That is part of the cost savings, less material needed. This is a good upgrade!
