Enafree Pre-Cut 20700 Battery Wraps Cover 100 Packs Protective Sleeve Heat Shrink Wraps(Deadpool)

These are for 20700 batteries but I figured they'd work on a 21700. The 20 and 21 refer to the battery's diameter in millimeters so 1 mm should not make a difference. Bah! Couldn't get them over the battery; too narrow.Since I also had some 18650s that needed a re-wrap, I tried these on them. After trimming the length just a little, they worked great on the smaller batteries.All in all, they're good wraps, look nice, easy to use... Aside from the size issue above (which is technically not the mfr's fault), my only complaint (and reason for knocking a star off) is that they don't come with the insulator ring.

Cut alot shorter than I feel safe using, still useable but bare coverage

Fits bigger cells well. Molicel 20700A has room to spare. Not too thin either, any thicker, and could cause fitment issue. Seem isn't very noticeable.

Great wraps

Too small to fit 20700 Batteries. Too big to fit an 18650 battery.

Works great and were cut perfectly
