I've used these in my FT-817s for years. They work great.

Anyone ever replaced the 9.6v NiMh battery in an FT-817 with three Lithium cells?
I know this is not a good thing to do, but the 9.6v internal charger should cut out at 10.4v and three Lithiums don't reach full charge until 12.6v so I don't think they will ever get overcharged. Stopping at 10.4v, they would only get to 3.5v per cell... Hummh... not very much charge at all on a Lithium.
But at least I'll get through this upcoming class with it. Bob _______________________________________________ Sent via [email protected].
