Default indi charger question/3300mhz battery question

I charged a few packs on my newly obtained integy 16x7pro and 16x9v6. These are the readings I got and i'm trying to interpret these. can anyone help. can you guys tell me the conditions of these packs? Im charging at 6A, discharging at 20A (max of charger) and voltage threshold is .06 V/c .036 V/p. Im kinda wondering why the pcak that isnt taking as many Mah, still has a better average voltage on discharge. (BTW, the discharge cutoff is .8V/cell on this unit and I cannot adjust it I dont think)

26:02 to charge
2573 Mah
9.005V peak

discharge (20A)
399 seconds
7.089V Avg

IS THIS PACK CRAP?

pack 2
to charge
3557 Mah
9.147V Peak
34M ohms resistance (what is a good reading for this)

discharge (20A)
615 seconds
6.947V Avg
36M ohms resistance (what is a good reading for this)

Thanks guys!

Dave

Dave what kind of pack is #1?
Is it a GP3300 or a Sanyo 3300?
Lower your cutoff to 5mv/c on GP's and 3mv/c on Sanyo's.
I dont think Pack#1 actually peaked.I think it false peaked.
Are they both GP's?Im guessing with Peak Voltage on them but I dont think #1 finished.
Do you have a discharge tray at all?

Its a GP pack matched by phantom. The pack is pretty warm so i figured it was peaking. if i lower the voltage from 6 mv/c to 5 then it'll peak even quicker (less voltage variance). I have no tray. Eventually im going to get a tray and just dead short them but havent yet.

your 2nd pack is right on, im guessing it is a 1.16 pack or 1.15 pack, as long as your peak voltage stays around a 9.2 and under a 36 resitance your packs should be in good shape. As for as pack 1 , it is prolly just a false peak, or a bad pack. try it again with the 16x9v6 and tell us what it says.
