One run showed a min 12.1v which is not bad... I'll have to check and see what the voltage was under a sustained full throttle pass.

One run showed a 10.1 dip so I ran that pack too low. That's a very brief dip and it bounces right back up to around but you don't to run them like that.

I have been doing some reading on rcgroups about cutoffs on the newer high-C lipos and they say to keep the cutoff above 3v per cell. You want the voltage to rebound to 3.7v per cell withing a few minutes after the run.

They used to say it's fine as long as it comes back to 3.0v but with the latest cells they say higher is better... I don't know how the cutoff translates to cars though cause it's a different ballgame than planes.

I think I will start looking at what the voltage is a few minutes after running to compare to what the cutoff/ low voltage was.

On a side note, I fried my ICE last night... one of the batt leads touched the power supply case while charging and smoke rolled out the charger. Not good. :031:
