Another day, another row of cells spot-welded. The new welder is a beast, making quick work of the 18650s. I’ve got about half the 48V pack assembled now, and I decided to throw a quick load test on the sections I’ve done. Hooked it up to a 100W bulb – nothing fancy, just wanted to see if anything went up in smoke. The voltage held steady, barely a drop, which is a good sign. Still, gotta remember this is just a fraction of the full pack. Not out of the woods yet.

Scrap lithium prices are still in the toilet, so the pile of dead cells in the corner isn’t getting any smaller. It’s a bummer, but I’d rather hold onto them than practically give them away. Generator was rumbling most of the day, as usual. Good thing 'Nothing Else Matters' on repeat can drown out most of the noise. I’m thinking I’ll tackle the BMS wiring tomorrow. That’s always a delicate dance, especially with higher voltage packs. Don't want to fry anything after all this work.
