Hi guys,

I've come across a heap of17650 battery cells which are testing quite well. I want to use my 18650 plastic holders to hold them and make a pack,but for obvious reasons they are not going to fit without a little bit of DIY ingenuity. So pretty much I have to add 1mm of thickness at each end of a cell. I've tried some tape which hasn't given consistent results.

Has anyone got any ideas I could try?
 
Electric tape could work but as you said its not 100% consistent. You can also use thicker heat shrink. There are 0.5mm thick ones out there that could work. Just cut rings and shrink onto the ends.

Dont forget that they can be a little loose as long as you just press the plastig holders together and then the soldered parts will keep them in place.
 
I already use some of these in my powerwall without any DIY ingenuity, they're held in place fine by the fuse wires... :)
