Withthe exception of prismatics, I don't think you'll find a LiFePO4
3S-size cell pack that is actually 4S electrically. A prismatic would
be a custom designed 4S, but you might take a look at Hobby King to see
what they have. Sometimes we all get lucky.

For each, I would like to see a battery pack with 4S LiFePO4 cells, instead
of the 3S LiIon pack the KX2 comes with.
Advantages would be the longer ultimate life of LiFePO4, a voltage closer
to 14V fully charged and a higher voltage toward the end of charge than the
3S LiIon pack, allowing higher wattage output as the pack depletes. I've
done this myself with the KX1 with very satisfactory results.
This would be a really nice substitute for the NiMh cells in the KX3 too.
I understand that finding a 4S LiFePO4 pack in a form factor that maximizes
use of the radio's internal space might be difficult, but I can wish.
