Maxwell Ultra-Cap's/Lithium cells hybrid pack

[Serum]

Sorry, my bad. it does 6100 joule. (6100 watts in bursts)

total amount of energy is 532800 joule.

I personally don't see the advantage of these cells, their internal resistance is too high, and with the right cells (read good quality) you wouldn't need them (which was my point) they would add nothing but weight.

Once they reached a lower internal resistance they will be more interesting in replacing batteries, with the ability of very quick charging.
