PVC Battery Sleeve
Save your damaged battery by re-wrapping it with your favorite color PVC wrap.
Remove the old wrap, insert the battery into the new sleeve, put the old insulator on the positive connection, and use a heat gun (or a blow dryer) to shrink to size. Do not overheat.
Easy as 1,2,3! Saves you money from buying a new battery. Keeps you safe from getting a short. Customizes the look to match your mod.
