18650 Battery Wraps

We highly recommend that you use a hairdryer when applying the new wrap. The old wrap MUST be removed first! Also, don’t lose the top plastic ring of your battery, it comes off with the old wrap and MUST go back on.
Damaged batteries can be dangerous, nicks and tears in the sleeves can cause direct shorts  lead to battery venting and even fires. This solution is not only cheap its effective and very easy to apply.
