So you think it’s worth doing with new cells too or just rebuit packs? Gonna make a 12s2p P42A pack very soon

it’s so quick and easy I do it as I check voltage… whether it’s worth it or not… like I said, I haven’t had one fail yet, to check and see…

me… I’d make a cell holder like you sent me… times as many cells wide as your charger will accept, put nickel on one end and nickel with a light spring soldered on the other… wire it up for 1s to hook into parallel charger board and bob’s you uncle

BTW… what wacky scale did you make that cell holder??? it certainly wasn’t millimeters… and the conversion to inches came out wacky…

It’s in millimeters, but I think it tries to export in 1/10th scale?

This is what I did with my ISDT charger, made a cell tray.

What are these cell holders you’re speaking of? @ZachTetra designed his own in fusion?

It’s just a glue up and welding jig for 4 and 2 half cells. I made 30Q 40T and P42A

They are free to share, I can make any cell type you want just message me and I’ll send it

I scaled it up 10 times and got it finally…

after I saw it… I knew I had to make some changes… but thanks for sending it to me…

I glue my cells in a manner that your excellent work would be problematic…
