As I matter of fact I can, and do. I'm glad to know that you know that multimeters need to be calibrated. Sorry for being off track, I was still on page one and didn't really bother to read the rest of the post. That is really unusual for me, sorry about that.
I just wish that NIST would get involved in determining "C" ratings. There needs to be some sort of international standard to determine what a "C" is and how its measured. Otherwise I am going to start buying 15C cells and selling them a 1.5H cells and just say that H is better than C. Until there is some sort of standard as to what a "C" really is, we need to be using accepted standards like voltage, watts, internal resistance, and mAH capacity. These can be tested by anyone with accepted standards and are quantifiable.
Sorry, I go on rants sometimes. I know that people generally don't know who/what NIST is, and what the deuce is a standard. BTW a standard is a piece of equipment that is used to measure other measuring devices. IE a really specific multimeter that is used to test other multimeters. Something like I use reads 1.002493mA when the multimeter you use reads 1.0ma. This ensures that your multimeter is accurate. And that is what I do for a living.
BTW, if I can get some standards that are accepted I would love to start doing some empirical testing on LiPo batteries.
