Battery Size Converter Gaskets - 10 Pack
Use these gaskets to fill the void in the tube while going from one battery size to another. No rattle.
Each order is for a 10 pack of gaskets. Recommended to use 2 gaskets per a battery.
18650 >>> 21700
21700 >>> 26650
NOTE: These only help with the circumference of the battery. If your 18650 is truly 65mm this will probably not work. If it measures closer to 70mm it should work.
