[Elecraft] [K2] K2 battery source in UK

[Stephen Prior]

Hello Guy

Yes, I had the same issue and that's what killed the battery for me.  By the
time I had realised and had increased my psu output voltage to 14.5V,
unfortunately the damage had been done.  Don W3FPR has some info on his
website and has provided a separate charging input socket for his K2 and I
might do just that.

Thanks for the reply
