Here we have some magnificiant metalic decals for 18650 type batteries (Keeppower 18650, LGT 18650...). 
 
Designed by KR Sabers. Available in chrome, gold and copper. 
 
These decals are to be applied by yourself as we canno't provide anyone with customized Lithium batteries due to transport regulations. 
 
Here is a video tutorial on how to apply the decals :
