"Or are they doing off the shelf kind of things?"

Yes....in combination with their tech.

What ever power arrangement is utilized or standardized for an industry segment, form the smallest to the largest battery, e.digital will siphon off the power at a least consumption rate for delivering a bit stream.

For instance, If say,  there's typical battery size utilized between 10 different companies within a particular CE segment.  If the other companies in crease the battery size to keep pace...e.digital will increase to the same size....and with that, there's a relative movement.
