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batteries can not be bought anywhere else, and these are truly the last of their kind as all newer 25R batteries have been replaced by the 25R5 (green).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.

Battery Bro has your back
Never worry about quality when buying from Battery Bro. We make sure you have the latest, greatest cutting-edge battery, every time.
18650 batteries are commodity cells, and as a wholesaler, we understand how important price is to your bottom-line. As such, we offer international shipping directly from Asia to save money in higher quantities.
We ship worldwide normally via UPS, FedEx (DAP), and Special Line (DDP) under Incoterms 2010.
21-day full refund
All battery cell orders fall under our 21-day full refund policy to allow ample time to test for authenticity and performance.
Battery Bro has been in business since 2014 and has never sold counterfeit cells. We value long-term relationships with clients and encourage our clients to performance test cells against official manufacturer specification sheets.
In Asia, 18650 batteries are binned by quality into A, B, and lower bins. C-bin batteries are often recycled from battery packs. Lower bin batteries will underperform and may be dangerous.
We will only provide A Grade cells, unless specifically required to otherwise, for example, some clients may prefer Grade B Chinese cells for low-cost ESS projects. We can also confirm batch-date code, run testing (like impedance/voltage/capacity), and handle other IQC requirements.
