We have tested all the leading suppliers on the market and are convinced that Skeleton Technologies has by far the best offer. The lowest internal resistance (ESR) and highest efficiency levels of Skeleton’s ultracapacitors lets us explore new solutions that were not thinkable with other products."
Let’s make energy storage simple and tailor-made just for your needs.Share your challenges, we'll come up with the solutions.
SkelCap Series - large supercapacitor cells
Superior power & energy density at a competitive cost in the most popular large form factor in the industry
The SkelCap supercapacitor series brings the benefits of our patented production technologies to the D60 form factor, the most popular cell size in the supercapacitor industry. Class-leading performance and a large variety of options offer you the upper hand over the competition.
SkelCap cells are available at 2.85 or 3.0 V with a very low ESR, or internal resistance, long lifetime, and very high power.
