[Elecraft] 14 volt batteries?

[Ignacy]

Most rigs are designed for a range (13.8V +- 15%). IMD3 are better at higher
voltage, but excellent IMD3 with predistortion can make this point moot. 

Many computer chips operate at 1.5V, and conversion from 12V is normal.
Expert amp 1.3k operates at full power from 90 to 270V.  Apache 8000 has
12V/50V conversion inside.  

With newer generation and predistortion + more intelligent design, radios
may limit themselves to max power at given voltage, all with excellent IMD
and high efficiency.  Say 80W at 10V to 150W at 16V.
