I favour Lithium Iron Phosphate cells because that chemistry seems to be
immune to thermal runaway.
(That's what I'm installing in my boat as a propulsion battery bank for
an electric motor.)
However, charging them properly (maintaining equal voltage in each of
the cells of the battery bank) is, I think, more of a design hassle for
a portable rig like the KX3 -- or whether suitably small Lithium Iron
Phosphate cells are even available.
I expect that the Ele-team has made a good choice given the present
state of the art.
