I remember research right?
I’ve done a lot of research on this lithium topic. A lot. And after awhile, well, some of it starts to blur together.
I saw a guy putting a cell log 8 into his Chevy Volt battery plug and getting live results from his battery. Voltage checks down to the .00X of a volt. How cool is that?

Canada Day is officially Christmas Day for me
Woke up at 5. Yup. 5 hrs of sleep and I’m getting dressed and running out through the cold morning dew to the solar shed. Time to check the first night of lithium battery goodness.
47.6. That’s the voltage of my battery pack after running over night.
You would think I got enough of all this last night. But nope.

And I am too
In celebration of Canada Day the lead is out and the lithium is in. Canada’s first diy Chevy Volt solar ESS is live.

The new battery box
The new battery box is under construction.
Keeping with the recycled theme. The box is built from the pallet the battery pack came on. That and some off cuts of plywood from another project. Sweet.
So a quick checklist:

Will flames erupt?
Testing of the charge / discharge performance begins.
- Added: Victron 48-1200 inverter. Would have preferred a slightly larger/parallel design. But this will suit for a year or two.
- Cheap chinese ammeter/voltmeter.
- Hooked up the TV for a load. And watched a movie. Perfect testing conditions.

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.
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.

Did a quick drawing of a bobolink. Thought, wonder what he’d look like if I could see ultraviolet?
And did I see a redheaded woodpecker. I believe so.
Continue reading Quick, fanciful imagining of a bobolink
Took apart the middle sized pack. 2 48s and a 24. All cells test at 3.83.
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.
