AUTHENTIC GRADE-A BATTERIES GUARANTEE

The Panasonic B is the most famous out of all 18650 batteries. When first released several years ago it was the highest-capacity 18650 cell mass produced and thus an essential ingredient in the rechargeable revolution and for the adoption of electric vehicles like the Model S (which has been powered by the Panasonic 18650B for some years). It is still a frequently requested cell for custom packs.

Quality guarantee

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.

• Did you know? In 2015, an e-cig shop was sued for one million dollars when a battery short-circuited in a customer's pocket. A safety booklet could have prevented that and protected the retailer from a lawsuit.
