This was one of the best 18650 cells ever made. It handles high current loads well (a max. continuous discharge of 20A) and has a good capacity of 2500mAh. As such, this has become a go-to cell for many industries. This cell is now known as the 25R2 (blue) to distinguish it from a newer version of itself, the 25R5 (green) which came out in early 2015.

The 25R is now completely replaced by the green 25R5.

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.

Battery Bro guarantees that all our batteries are Grade A.
