Go with LiFePO4 cells
Yes. This ham-friendly company sells a wide range of LiFePO4 batteries.
Charge before you leave home (all Li batteries require a charger
designed for their specific chemistry, voltage, and capacity), connect
to your KX2/3 external power jack. Choose the capacity/weight that suits
your planned use.
$50 will get you 3Ah that weighs 13 oz; add $15 for the charger. A 6Ah
battery goes for $80, approximately twice the weight. I paid about $195
for a 20Ah battery that weighs 5.4#, +$20 for a faster charger.
