[Elecraft] KX3 and charging batteries (when, and why do they get hot?)

[Arno Dienhart]

Mark,

 

Thank you for this excellent response. This is exactly what I need: solid
advice with rationale behind it.

 

I checked a few things. All eight cells are now at 1.4V. When I turn the TRX
on, the integrated meter shows 10.5 V now. I think this morning, when I
checked after the full charge, it showed 11.6V. Not sure if that is a good
sign after only having it on for a bit, tinkering.

 

The BAT MIN was at the default setting of 10.0 V. I changed it to 8.5.

 

Kent briefly contributed his opinion that a wall wart would not be good for
charging the KX3 but did not give his reasons (I will not operate it off
that adapter). What is your opinion, particularly regarding the wall
charger's specs of 13 - 15.8V (@960mA). Is this peak voltage potentially too
high? Other than that, I fail to construe even one reason why this adapter
would not be fit to feed the 200mA charger or cause my heating issue.

 

Thanks a bunch!

 

73,

Arno
