This view has been widely accepted, and LiFePO4 is the de facto standard 
for replacement of other nominal 12V chemistries. Bioenno Power sells a 
wide range of battery packs, and is very ham friendly. Pre-COVID, they 
have exhibited at ham conventions. Last I heard, they are being marketed 
by Ham Radio Outlet.

I own two of their 20Ah packs for portable use, and one of their 100Ah 
packs has been running the two K3s on my operating desk for almost five 
years.

With ANY Li chemistry, including this one, it is critical that they be 
charged using a proper charge regulator. I'm using a Genasun solar 
regulator with a re-purposed Thinkpad PSU. Genasun regulators are RF-quiet.
