21700 Battery Wraps

[Zaryk]

If anyone is looking for some 21700 battery wraps, I have found a source. They are not the best wraps I have used, but they are not poor quality either, about the same as the wraps that IMRbatteries carry. Also, the insulators they carry say they are plastic, but they are in fact paper/card stock. Shipping was fast, and prices are reasonable. They are located in the USA.

One of the reviews say that the wraps didn't fit, but I had no problems double wrapping my Samsung 40Ts.

Edit- I contacted them and they fixed the description of the insulators.

I just tested my 20700 wraps and they fit onto 21700s as well, but I had to remove the stickers.

I wasn't able to doublewrap my 2 Golisi S35 though, but their wraps are already extremely thick. Although the clear wraps fit over the top, they are way too tight to get the whole cell in, but changing the wraps when the actual ones are damaged, shouldn't pose any problem either.

My 20700 wraps did not fit my 21700 batteries at all. It just wasn't going to happen. If they were a millimeter larger they may have fit, but alas I had to resort to scouring the internet to find the ones I linked above, which fit just fine.

Mind if I ask where you purchased your wraps?

I got mine from fasttech. The clear and green ones.

Good to know, thanks for sharing.

My 20700 wraps came from IMRBatteries. I figured I would mention that so people would know to not expect them to fit the 21700s.
