Thanks Geist. That helps. I did not know that NiMH was expected to have memory. Again I do not claim to know much about electrons and how they work so I took what I was taught about NiMH not having memory as gospel. Obviously that was incorrect. It sounds like a simple solution, cycle the pack until it comes back to capacity and then run it down to 8.8 before recharging to maintain capacity.

Now I run Lithium on everything inside of all of my IMAC 3D big stuff and I have read a LOT about them. All indications are that Lithium does not have memory and I am see no indications of memory in my Li Ions. Do you agree with that or have you had much experience with them.. I have been running 2400 7.4V packs and its a pretty constant take 800/day out flying recharge and put 800 back.. It takes about 20 flights to run them down to 7.4V but I have only tried it once and since I see no indications of memory indiced capacity loss, I dont worry about cycling Lithiums. Now I am curious.

I wish they would come out with a regulated lithium pack for the 9Z.
