Someone earlier made a comment about the Internal resistance of Sanyo cells being poor compared to IB4200's. I tried to find the post but couldnt be bothered going thru them all again.

Anyway, Here is the actual data taken directly from the manufatcures data sheets. And anyone can confirm this data by simply downloading the data sheets and looking for themselves.

IB4200 - Typical 5 milli Ohms.
RC3600HV - Approx 4 milli Ohms.
GP3700 - Average 3 milli Ohms.

That does explain why the Raw sanyo has a higher average voltage at 10 amps than do the Raw IB cells.

I cant test my GP3700's as all 6 cells are stuffed. I expect they would have the highest average voltage from all of them based on the Internal resistance.
