Anyone else got some comments on 30Q vs MJ1 in terms of cycle life? Was hopping for a few more opinions or data points.
The solder definitely beads up and doesn’t like sticking to the non-scuffed side, but both sides formed strong bonds and are solid!
Sounds good! If you really want to make sure it’s 100% legit take a cutoff wheel to it and make sure it doesn’t spark. The only reason I’m telling you to do these tests is because I’ve had bad experiences buying wide nickel from China.
yup, passed the spark test! I’ll post on the saltwater in a few days
Sounds like you got the good stuff!
Damn bro how many batteries do you need?
I expanded my capacity for building them to sell. Couldn’t sacrifice quality to keep up with demand. (The 12S7P is mine tho!)
nice work, man
Is that .25mm wide nickel?
I hate cutting all those little strips of the 10mm, lol
Thanks! Yeah its 25mm wide .2mm thickness from fogstar. It’s a little small for 21700 cells tho so I’m going to get some 30mm wide in the future for that specifically.
Wait fuck…can you do square grid 21xxx cells at all with 25mm nickel?
Hmm…fuck
Is 30 enough then?
Yeah, 30mm covers from edge to edge of the positive terminals the same war 25 does the 18650’s. I would definitely go 30mm for 21 wide cells
Hmm fuck. I will be in the same boat
Someone here needs to buy like 20kg of 30mm by 0.2mm nickel and distribute it to the rest of us…we need a battery building supply GB
Im just gonna use 12mm. Only got 3 batteries to build and i have heaps of 12mm
Can still use 25mm for the fold over tabs… all is not lost.
What do you mean fold over tabs? The 10awg to cell connections?
