You can solder on solder tags. We advise against soldering directly on the accu, the heat might compromise the accu.

We offer U-solder tags (also called C-tags):

And Z-tags:

The difference is the orientation of the tags.

 Tags are added on demand, thus after the sale. So deliver time is a week extra. Cells with tags are custom made and thus not liable for cancellation.

Size of the tag 30x8x0.15mm

Material: pure nickel
