18650 Flat Top Battery Terminal Insulator (20pc)
You know that small piece of plastic-y paper placed around your battery's positive pole? That's actually pretty important—it helps to keep things working in your battery cell as they should be. So if you happen to lose this small component (perhaps while re-wrapping), it may not seem like a significant issue, but it can still cause your battery to develop problems without notice! You should replace it as soon as possible—why not give this tiny but important piece an upgrade? These 18650 Flat Top Battery Terminal Insulators are thicker than most for increased durability and resistance to damage. Plus, they're self-adhesive, so you don't have to worry about losing your investment to the wind.
