Jason: I really don't believe your info on testing the C rate of a 5000 parallel cell makes sense. I agree with O'Brain that 12 gauge wire and Deans connectors can't be used to pull 200 amps so why are you claiming this? Below is a piture of our how our supplier tests a pack. There not using 12 gauge wires and Deans connector when using 140amps so how can 200 amps work ?
I'm sure that the TP pack is good and has good performance but it's impossible to use 12 gauge wire and Deans connectors to discharge cells at 200 amps.
