ok, got it done. what I did, now, hold on, this is highly technical.
I have 3 brands of batts =3 different colors. I marked a R for red, B for blue, and Moli for the Moli's.
marring them = no mark, 1 mark, 2 marks.
also. you may remember that I said the larger wraps did not work on the 18650's. well, I was using a hair drier, and burning my fingers doing it, with kinda crappy results. they said a hair drier works = NOT.
then I grabbed my heat gun out of the garage = BIN-F'n-GO !!!!!!!!!!!!!!!!!!!!!!!
6 seconds and the wraps are tight as hell, and no burnt fingers.
I also put the new wraps over the like new originals = no issues.
oh, the larger wraps, when putting on a 18650, just trim a little off.
