have lower energy density than regular Li-Ion rechargeables but due to lower voltage one can use 4 of them for about 14 V max as opposed to 3 of the regular ones with 12V max. For K1 the 3 Li-Ion would be a better fit as 10-12V is sufficient and weight is half of LiFePO3. The last one are better IMHO when the minimum voltage is >11V, e.g., for regular HF radios including K3.
I have the regular Li batteries in K2 for many years and never a problem except higher Ah at 1/4 weight of lead acid.. The only trouble is a need for connecting to an external charger. A simple choice is a small board that attaches to a laptop charger and contains adjustable 1A regulator.
