[Elecraft] Internal Battery Charging Question

[Steve Holton]

The battery wants to see 13.7-13.8 volts as I understand it. So if it's 
measured as 13.8 volts at the cathode of D10 there is no ambiguity 
regarding the which diode you have at D10 and how much voltage drop there 
is across it.
As the K2 manual says the internal voltage and current measurements are 
+-5%, which I found to be the case in my case 3%, and this is enough of a 
variance to set the level ideally for the proper charge of the battery.
