We use the 21700 heat shielding wrap to avoid unpleasant situations from worn or damaged battery covers, such as short circuits. By changing damaged covers, we can increase the battery life and change the look of the old battery.

To apply the new cover to the battery, simply remove the old one and place the new one, then heat the edges above and below the battery. In this way you will apply the cover completely by wrapping and protecting the battery.

Transform your old and damaged batteries. The dimensions are just for application on 21700 batteries.
