I just finished making the new cell model with highly accurate detail on the tab. Fairly certain they are identical each side but should check.

this one is also too big, but at least two rows should have contact.
Who ordered the right ones?

So they must exist. But I wasted too much time on their page already.

@Arzamenable Would you be so kind as to let us know the part number of your clamps?

I might be interested too if you can find a viable shipping service and want to split costs.

So all the regular shipping services do support shipping batteries as long as they are declared properly. The issue is that parcel forwarding services don’t support batteries, so would need someone to accept them and repack them for international shipping

Guessing the website doesn’t support international shipping directly?

I spent $16 on shrink wrap (shit Ace hardware prices) for this project. That’s more than half the cost of the cells in the battery. The cells are probably like 1/3 or a 1/4 of the cost of the pack. It’s wacky.

I’m at Serineh’s house. No Eskate stuff here. Let me look through email receipt history.

I also closed those crimps with a vice. So, that helps. I sold a few bits of neglected gear and am jettisoning projects I don’t love.

I’ll finish my packs in 4s configurations. Bc @MoeStooge at 8s, me at 12s, and future me at 16s all might have a use for them.

Don’t try to make a tall stack like mine with the vice method. You would need about 7 hands.

My pack is ready to charge up


This was the cause of no reading the the balance lead. Making sure you get the wires flat before crimping and having no cold solder is important. I’m lucky this was the very top/bottom cell I did first before I figured out what I was doing.

Easier said than done, I am aware of this. It’s like surgery on a semi conscious electric eel
