"Powerizer Batteries", with capacitors?

[Serum]

They can take some peaks from the currentdraw, but it depends on the quality of the caps how much current they can handle.

And the 2nd thing is that those caps are only able to absorb the smallest peaks, because they wil be empty pretty soon..

The reason for using caps on an esc serves a whole different purpose. (to protect the batteries from being puls loaded)
