10m should be enough for 5 batteries at least. I usually use 2m or less per pack, depending on arrangement.
my malectrics is powered by 3s3p SPIM08’S and has no problem doing .2mm but that’s really heavy nickel. I use .15 thick for the 30q’s and save the .2mm for the high amp cells (40T’s HG6, etc.). It’s nice, but it’s hard to cut and heats up the welder faster (so, go slower).
I just got a 10m roll of 25mm x .15 in from China and more on the way. I could peel you off a couple meters if you don’t want a whole 10m.
sadly the one I took apart was just as bad (worse?). In fact, the first question I ask now when someone asks if I can fix their battery is “who made it”? if the answer is “China” or “Tiller”, I respectfully decline. “Sorry, that pack is worth scrap value for those cells”
I think people who make batteries eventually get overwhelmed with demand and are either forced to cut corners (figuratively, lol) or turn away business. If the income is needed, you’re really only left one choice.
That said, I found it is possible to streamline the workspace and process to make the work go faster. I’m doing a write up now, but one example is using wide nickel instead of dicking around with all those teeny little strips. I saved hours of work just by switching to wide nickel. And the battery is arguably better and safer.
Thanks for the offer but not sure shipping to the EU would be worth it, I’ll probably pick up some nickel from nkon (the issues they had should be sorted now right?) or fogstar depending on who has the cells cheaper.
Need to check what batteries my friend is using and get like 3m of nickel and some fishpaper and shrinkwrap.
yup, I got some on the way from Fogstar now. Supposed to be lab tested, and they have a reputation to lose so I feel good about. would be silly for it to get here just to go right back, lol.
Nice to be able to get it all in one place like that
It’s funny yuo mention tiller packs cause I was just watching a video @DEEIF posted on his ground zero board where he’s at a racing event and Dave is seen potbellying around, and I thought “hmmm, I wonder if he’s still building batteries?” I never actually got to see his work I didn’t know his packs were atrocious! Unfortunately that link is broken and I can’t see =/
