Anyone heard of or used Skeleton Ultra caps?

[Dragonsyph]

Came across these SkelCap SCA3200 which are made from curved graphene.  Are XS and Maxwell even made from Graphene?

You can buy 10 of them for only 550 dollars and from the stats below they look way better then XS or Maxwell.

Pretty much get 2 banks for the price of 1 XS bank.

Skel caps below.  https://www.skeletontech.com/all-products

THEY also have caps that have a rating of 110 kW/kg    which seems INSANE..  But i couldn't find a price on those.

XS caps below. 

Looking at 53kW/kg  VS 23kW/kg,  is the right right thing to look at?

Where are you finding 10 for 550?

Where are you finding 10 for 550? 

From there website, turns out thought to get them shipped to me they want 349 dollars shipping.   I posted link above. 

So if you dont live in the EU then these are not a great deal lol.

Been doing a ton of research trying to find a Graphene supercaps that are made in the USA> 

But it seems the USA is fare behind in the cap game.

Yes, Maxwell, Ioxis, and a few others are all "ultracapacitors" made with Graphene composites.  All are similar in their approach.

Some smaller Lithium cells are starting to be made with graphene

And i've seen specs of ultracaps with lithium doped sheets for higher voltage performance.  Lithium Caps!
