Heat Shrink Wrap for Packs...
Ive been Using Trinity Cell Shrink wrap for a few years now. seems like when i put a cell in the shrink, its to loose for when i start to heat the shrinnk, causing sometimes to crinkle or kinks
But anyways, Friend bought some promatch packs from the Hobby shop, came with heat shrink, I built his packs for him. That shrink seemed to be awsome! Thicker to stand up to the abuse, and the cell was a tighter fit to make shrinking easier.
What kind of shrink does promatch send with their cells? Id like to switch to that kind from now on!

I assume this is the same as they supply with their new packs. $0.10 each.

Even better, pay them the $6.00 to assemble your new packs. They have a superior technique for soldering that gives a lower IR than anything I seem to be able to do so far. They use minimal solder. However if your packs get beat around you may want to add some shoe goo to reinforce the packs because the solder joints themselves are not as strong as one covered in solder.

I meant that these ARE shrink wraps they sell separately for you to build your own packs....
Sorry, I didn't mean to imply you didn't make good packs, just offering info, since I have no way of knowing your level of expertise I covered all of what I thought might help
But if you've never seen them you should check out their assembled packs at least once. They must have some special equipment to do this... it's like a spot weld, almost no solder, great bar to battery contact. After sending a pack in to get checked out, I talked with them on the phone and got ideas how to do better on my own packs. I thought my soldering was fine before but
I saw a big difference in performance 
and I have improved my own work also.
