I last worked part time at the local hobby shop in 2015. Leading up to that, we carried all sorts of batteries for all sorts of uses. We had a display for a long time that was just for Li-on batteries, that were flat packs, mush like the typical Li-po's are. I don't think we ever sold a one of those in any size. I tried to find out information about them so I could try to sound intelligent about them if someone asked, but really couldn't nail down the "why" we even stocked them. I think they were eventually sent back for credit and they haven't had anything like that since. Then fast forward to recent times and many stunt grunts are using Li-on batteries. So, what goes around comes around again someday?
Who's got a quick, short history on who started using these first and when? My memory of them is being mention by Paul Walker a few years ago, but is that where the use started ? Is any other part of the hobby using them for flight packs? The R/C pattern guys maybe?? I'm just curious to know.
Type at you later,
