I've been re wraping my batteries for years this is my first time with liion's wraps these were terrible it took 7 wraps just to get 2 21700 wrapped using a hair dryer on low it kept splitting the sides open where they have a really bad crease in them.

Hi Joseph - Thanks for your review. We sincerely apologize that you ran into issues when rewrapping your cells. The trick to using these wraps is not to hold it on your heat source for very long, or you will run into the same issue you had with the seam splitting (the wrap got too hot). Personally, I move my batteries over my heat source without letting them hover over it to make sure that the wraps are even and do not split.
