ESC cut-off voltage for 3S lipo?


I got 1 Phoenix 10 and 1 Phoenix 25 ESC. According to the 2 manuals, the Ph 10 says the ESC cut-off voltage for 3s lipo should be 9V while the Ph 25 says the ESC cut-off is 7.2V. Any idea which one would be more appropriate?

Thanks.

There are a lot of threads on this in the CC vendor forum and there does not appear to be consensus on this issue. I too am waiting to see what the real answer is.

I'd use the 9v on soft cutoff and the 7.2v on hard. Especially with some vendors packs where '15C' and '20C'; ratings means volts drop to around 2.5v per cell under load.

Wrong answer. Thunder Power and Apogee both state very clearly that their batteries must not be used with a LVC below 3.0 volts per cell.

The 2.4 or 2.5 volts per cell was (is) OK for gen 1 LiPolys but will severely damage the now generation of LiPolys from most manufactures. Kokam may still recommend (approve) odf a low LVC,I am not sure.

LVC as explained by Castle Creations.
