I'm running a KO Esprit 2 Vantage with a Spektrum 2.4GHz conversion, and being an oldie I love it. I have no need/want to change it for any other radio in the near future, but it is starting to be let down by its somewhat aging batteries.
It is the version with the soldered-in packs of cells (2x 4xAA packs, permanently connected). There are no contact pads within the battery slots so dropping to individual cells can't happen.
I'm wondering if there are any lipo packs out there that will fit into the old KO arrangement, or am I just best making up my own packs from some AA nimhs?
