We’ve all had a battery wrap tear on one of our 21700’s. Some of us continue to use them like that, which is incredibly unsafe. Others fix it with electrical tape, or just toss them in the bin. Well, now you can save all those unsafe batteries that have compromised wraps With high quality designed and unique wraps.!

Tips

• 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.
• 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.
