Well, a few months have gone by as I have slowly acquired more batteries, and I'm finally at the point where I can build out my first pack (~100 usable cells).
It is quite a pile of cells:
In total, I have 143 cells, with 105 in the range I want to use, 6 higher than the range, and 32 lower. I'll probably use some of the 32 lower capacity cells to build out a smaller test pack capable of 12 volts. That will let me figure out things like soldering and bus bars basics.
My plan had been to build with a 400 mAh variance, but I've ended up with cells from that range from 2000 to just under 2700 mAh. That's close enough for a first pack build. Here's how the cell repacker calculated the cell distribution for my 7S14P build:
This puts me closer to needing to sort out an inverter and some sort of small-scale solar array to play with!
