Product Description

Neodymium Disc – 10mm x 3mm Rare Earth Magnet – Battery Spacer

These magnets are used to space batteries. 

E.G. The Maxtoch X-Pro Hunter Torch takes 2 x 21700 batteries.
You can remove these batteries slide in adapter sleeves in to torch to use 2 x 18650 batteries.
But 2 x 18650 batteries are too short.
To fix these batteries to the length required to be used instead of say 2 x 21700 batteries you place 1 of these magnets between the 2 18650 batteries, (see image above).

Therefore any torch or product that requires 21700 batteries can be interchanged to use 18650 batteries by using these the required adapter sleeves (CLICK HERE) and 1 magnet.
Convert a 21700 Battery product to accept 18650 batteries.

Nothing complicated here, just remove the 21700 battery, insert the sleeve / converter and then insert a 18650 battery, magnet then another 18650 battery.
See the image.
