I do believe I saw it here somewhere :confused: But have not been able to find it again. I'm looking for the way to figure out what a 40 amp matched pack would be at the more familiar 35 amp matching.

this is directly from the TQ Cells website:

How to convert runtime to mAh? ... Multiply runtime by discharged amps then divide by 3.6 ... 400s at 35A = 3889mAh
How to convert 40A runtime to 35A runtime? ... Multiply runtime by 40 then divide by 35 ... 380s at 40A = 434s at 35A
How to convert 40A AIR (actual internal resistance) to 35A AIR? ... Substract 0.1 from 40A AIR ... 1.6AIR at 40A = 1.5AIR at 35A
How to convert TQ Cells' 40A avgV (average voltage) to TQ Cells' 35A avgV? ... Add .007V to TQ Cells' 40A avgV ... 1.233V = 1.240V

I even looked there but missed it. Thanks Rusty now I can figure things out !
