Best 18650 Battery 2015 April 14 2015, 9 Comments

What is the best 18650 battery in 2015? It's a question we get asked a lot, but like all things the key is: it all depends.


Let's lay out the major 18650 battery manufacturers. There is Panasonic, Samsung, and LG. Sony cells have fallen in production, as they focus more on li-po - soft cells for use in mobile and tablet.

Panasonic provide some of the best cells for electric vehicles. LG, Samsung, and Panasonic all produce 18650 batteries for laptops. LG and Samsung produce more high-drain cells. But after all is said and done, all three of these manufacturers have very similar battery lines.


You should consider whether your application calls for high-drain, or high capacity batteries. These two specifications are always at odds. The higher the capacity, the lower the amp drain. The higher A rating, the lower mAh rating. 

Electric cars depend on long drive distances and prefer high-capacity cells. Whereas vapes, mods, and power-tools depend on high-drain batteries with a high A rating.

Currently, the highest-drain 18650 in production is rated at 30A. But almost all production is focused lower at 20A.

The highest capacity 18650 batteries fall short of 4000mAh, and the ones readily in production are closer to 3500mAh.


For vapes and mods we recommend the Samsung 25R.

For general electric vehicles we recommend the Panasonic BE.

Laptops, high-performance electric vehicles, flashlights, power-tools, etc. all have special needs and there is no exclusive answer to which battery is best. It all depends on your application.
