Batteries get locked up
In this installment of the lithium build I will install threaded rod. Use the sawzall. Get a little, er, nutty. All to bolt the lithium batteries back together.
Fancy high tech threaded rod assembly routine.
What to do? When you take the packs apart they expand. The top cap holds the top of the battery together, but the bottom spreads.

Took apart the middle sized pack. 2 48s and a 24. All cells test at 3.83.
Second pack is on the bench. 2 48s. One 24. 120v nominal.
This is probably where I should say, “don’t try this at home kids.” That’s 120v with about 4 kw stored. Things would get very ugly, very fast, if you make a boo boo.

We have a winner!
The first test is complete.
Okay. Test #1 complete. A complete success. At aprox. 10 a.m. my batteries reached 48.26, went into absorb and then float.
The tristar worked perfectly.

TriStar MPPT test begins
The Volt battery pack build has been predicated on the idea that I could use a custom charge profile for my twin Morningstar MPPT-60-150s. Research shows a variety of experiences. Huh?
Test #1. Here’s the controller showing the voltage of the battery. And tomorrow morning we’ll see how the new programming works.

The start of a beautiful relationship, I hope
I’ve been talking about lithium for some time now. Its just a better battery. Did it come time to put my money where my mouth is?
Or did I decide to bravely go where few have gone before?
Either way: I’ve taken a calculated gamble. I found a 2014 chevy volt battery from a wrecking yard. Untested. And I bought it.
The nitty gritty?
The wrecking yard in far far far north Quebec was nice enough to deliver the pack 1/2 way to my house. They drove for 3.5 hours south. I drove 3.25 hours north. We met. Slid a pallet between two truck beds.
The eagle has landed. The pack is in the back.

Bargains galore as the fall work season begins
Well. I’ve been a lazy lazy boy this summer. As always. Living off grid is great. Now here’s Gisele, the french dominatrix cracking her whip. I’m back to work. Sort of.
This is as far as I’ve gotten so far. I have to say it’s going pretty slow. Part trickier than I thought. Part getting back into the work groove. Three, three, three kinds of siding, ah ah ahhhhh

The spray foam gun: essential tool for the off grid build
HT-300 insulation foam gun with two types of Tytan foam.
This is a pic of the gun I’ve been using for the last two years, or is it three, and it illustrates one of the key Creeky top tip appliances for off grid.
