THX for the link and further comments.
If my google-fu is what I hope, it looks like “lipo” are chosen for flight batteries more commonly as an issue of weight.
Of course now there are dozens of “lipo” battery choices for flying, but use of LiFe for ground station equipment and transmitters is common.
I put lipo in quotes as it isn’t usually specified beyond that, everyone just knows what it means…
Which I haven’t yet found, will keep looking, but what is the exact full name of the chemistry in the common hobby 1 to 6 cell flight batteries, 500mAH to 5000, bare naked packs we play with?
