Thanks Alex and Kody
Woops posted the video twice. I wasnt sure if I had posted that video or not.
I decided to super glue the card sleves together then wrap around the outside with gaffa tape. I then spent the long tiring job of soldering the cells together. I decided to use wire as its all that I had as well as some one told me that it can transfer more current then battery tabs.
I have one pack done and I finished at around 1am in the morning after starting making the pack at 11pm. Once you start you just cant stop!
I didnt charge the packs but I checked that the packs retained charge well and I put two large fans next to it to cool it down.
One pack done....two more to go.
