I really don't go by what the charger has declared peak since it varies too much. I go by the "race" voltage which in many cases is between 1.39V to 1.44V per cell after disconnect from charger. So a good pack for me would have about 8.6V before I set it on the track. The charger peak value will always be higher since in order to charger a battery it needs to create a higher potential to push powre into the cells. The higher the charge rate in amps the higher the chargers peak voltage will be to create that push.
thanks again for the replies. what im doin is making some of my 6 cell packs 5 cell. just wanted to kno what to look for when i cycle the 5 cells. i just take out the cell that consistantly 'dumps' first on the DPD. mainly making some packs for pratice but i just incase they are good for racing i wanted to know what to look for.
The peak voltage is just how much voltage was needed to push the amperage past the resistance of the cell. A higher peak voltage just shows that that pack has more resistance than a pack with a lower peak voltage.
