I use the 3-cell lipo batteries that I use for my R/C planes. They are small (~1x1.5x4"), 11.1v @ 30A! I've run my K1 or KX1 for nearly a week on a single charge, operating as much as I cared to. R/C use demands lots of current for a relatively short flight of 10-15 minutes. When they no longer deliver a long enough flight, I retire them to ham radio use where they seem to last forever and the relatively modest current draw.

For those of you who operate portable regularly, what capacity gel cell and do you recommend for K1? Any particular brands of gel cell and charger?

Weight is not a big issue. I won't be hiking, just trips to parks, qrp Field Day, as well as home use during power outages.

Tnx es 73!
