Strapping Cells

I picked up my packing strapper today. I chucked together 10 cells to do some BMS testing. I used black plastic end caps so it would be less obvious what's going on in the photos, I'll have some aluminium end plates made up before they go in the car. The strapper came with a big roll of this very strong green strap, hopefully it's durable enough, it certainly seems like 2 or 3 straps will restrain the cells.

The crimper (not shown it the picture above) makes a ridge that stands up on the back side of the crimp. This can be hammered over (with a suitable spreader against the cells!) in order to pack the cells closer together.
