Real Battery voltage #'s
I know the industry standard method of creating the battery voltage numbers on the tags...but what are some 'REAL' battery voltage numbers?
What I mean is - since I race 5 minutes I want to know what the 2 min. 30 second voltage should be with a MOD load...so for yucks I'll say at 35 amps.
So at 150 seconds into the discharge @ 30 amps what SHOULD I expect to see for voltage. (6 cell - 4 cell shouldn't matter, the AVERAGE Voltage per cell should be the same if the load current is the same)
Most of my 4200's I've tested have either 4.8 or 4.9 volts at this point.

Go lipo.. voltage is MUCH more consistant.

Just ran some cells thru my CE matcher at the 230 mark they were 1.248 at 35 amps

Phroz -
This isn't a debate of LIPO vs NIMH (I already WENT lipo) but I still run some events with NIMH and am looking for valid info.
My packs that I've tested the best I can get is closer to 1.225 @ 30 amps at the 230 mark - and I'm curious how far OFF that is compared to some of the HOT PACKS.
I also have a couple classes where we are relegated to running old 3800's, and my old 3800's at the same point are closer to 1.166 @ the 230 mark.
