[Elecraft] KX2 External battery question

[Tim McDonough N9PUZ]

The 12V Bioenno batteries have an internal battery management circuit. 
They require 14.6 - 15 Volts input to charge properly. The BMC will 
prevent overcharging and Bioenno Support says it is safe to leave the 
charging voltage permanently applied.
