We don't the c rating, but are just curious about the energy flow of a completed pack. I am sure that the cells have the c rating that they claim (virgin) from all reputable manufactures, but what happens after all the soldering and such are done, and at what point does the gauge and quality of the wires, esc, and motor past the pack begin to limit the flow of the pack. c rating seems to be kinda like car hp a company says 400hp but after it goes through the drive train you end up with with 380 to the wheels. If you keep upping hp and not upgrading the drive train there will be a point where the hp will break it. I will get an email out to you for some guidance on the matter of a good solid test. thanks
