Turnigy 2s1p 5000 mah -

Today I found some time to put some Deans connectors on the 4 Turnigy packs. I charged them using my CellPro 10S and took one pair of them for a spin in the ERBE. The performance is very good, I don't detect any difference between those Turnigys and my 2S1P Neu 5500 mah 30C/50C packs. I did not have time to find out how long they ran before hitting the LVC which is set at 3.2 V. Maybe tomorrow. The fit in the ERBE's battery compartments is tight to say the least because of the 10 AWG wires coming out of the side corner. If you don't have those little spacers installed on the battery doors (check earlier in this thread) you will have some difficulties closing them.
Here's some numbers on the internal resistance of each cell that came from my charger after the packs were charged to 100% capacity.
Pack 1:
cell 1 = 1.6 milliohms, cell 2 = 1.8 milliohms
Pack 2:
cell 1 = 1.6 milliohms, cell 2 = 1.8 milliohms
Pack 3:
cell 1 = 1.6 milliohms, cell 2 = 1.8 milliohms
Pack 4:
cell 1 = 1.8 milliohms, cell 2 = 1.7 milliohms
Am I correct in saying that these low internal resistance numbers are a good sign that these packs are truly 20C/30C? And not 15C/20C. I read somewhere that higher C rate cells have lower internal resistance.
