Volkswagen E-Up! Li-Ion cells

Okay. So if you want to make a 12s1p battery with the 37Ah cells, you would need to cut the spotwelded strips and then solder the cells in the right orientation?

Correct, and its not an easy task, as the bus-bars are aluminium. If only they were copper. TIG or MIG welding is the way to to I guess.

Damn it!, was hoping that the connections where copper. Aluminium is a pain to solderā€¦

Even a bigger pain to weldā€¦

Not if you know what you are doing :wink:

Hello, Iā€™m wondering if these are internally protected, as i have 104 cells that seem to be dead 0V, which seems to be odd for me.
