Here is a list we've compiled of obvious scammers or fake product listing to help the DIY community avoid these sellers.

Note: Be aware that these sellers tend to create new accounts after too many complaints occur so you may need to rely on detecting the same products or dodgy manufacturing we've uncovered with new suspicuious sellers.

 

WARN: Any 18650 cells over 3500mAH is highly questionable, check reviews for complaints on lack of capacity
