Its cloth tape. The whole pack is fully siliconed together, i didn’t see the need to waste fish paper in this application.

What size of nickel am I looking at here? Im just getting into spot welding and Im trying to figure out what to buy.

Most of it is 12 x 0.15 with a little bit of 25 x 0.15

I would recommend just getting the 25mm stuff

10mm x 0.2mm
15mm x 0.2mm

Thought I’d ask here but can anyone see anything blatantly dangerous or wrong with my pack?

How important is it to shrink wrap? I’m fairly tight on space lol

Haven’t finalized a connector design just yet. Think of going XT60 on both sided to make them modular although the BMS connects everything together so that might be pointless.

Hey, im thinking about building a 10s4p pack i was gonna go with a format like this guy.
https://www.youtube.com/watch?v=0-XMgzOsXWo around 5:10-6:10 it sparks a couple times is this a lack of fish paper insulating rings or should go for a different layout?

haha, heck yeah, he shorted the crap out of that pack, lol. It was a good reminder to him to tape everything off to prevent shorts.

to the point: folded nickel series connections are generally frowned upon in this community

Won’t intentionally weld over solder. I know it’s not a great thing.

forceps/soldering iron, step wise, walk along a braid.

I’ll make a gif When I get home. @Bindings_McGee was there for the start of this method, although initially it was a mess.

Those are the pictures we don’t post. :grimacing:
