AUTHENTIC GRADE-A BATTERIES GUARANTEE.
Beast "Pride your power" batteries were created by Battery Bro to raise the bar for what an 18650 can be. These are the first "art batteries" created, with help from artist Frank Teran. Frank has been a lead artist in games like Star Wars and Deus Ex.
The Kraken batteries are rewrapped Grade A Samsung 25R (blue) batteries. These original 25R batteries can not be bought anywhere else, and these are truly the last of their kind as all newer 25R batteries have been replaced by the 25R5 (green).
While the specifications of both cells are the same, many users swear by their old 25R (blue) "smurf" cells - and after these are sold there won't be anymore. It is truly a one-of-a-kind cell.
