Some if not most of the brands out there will most likely always go for the cheaper manufacturer to make more profit (Nothing wrong with that). How do they test the packs afterwards, who knows. If the people I've contacted yesterday are up for the idea I have in mind, we will find out soon enough what's real and what's bogus. It should also teach a lesson to all the over rated items in our Hobby. The only problem is, if there's still uneducated people out there always talking about the numbers, there will always be over rated products.
Example: A guy that drag races RCs went to my LHS to buy a brushless top of the line LRP esc. I was there with my ESC and offered to let him use it. He asked what's it rated for and I told him 200A burst continuous. He said the LRP was 400A per phase and I told him the rating they use is just to make it look good and I told him that no RC battery will be able to deliver such AMPs. Well he spent $200+ on the LRP and I guess it didn't work as he came back a few days later trying to return the ESC. So I offered him my ESC again and this time he said he was making his own, but I never seen it. I should've told him the specs on my ESC using the pulse AMP rating was 250A X 3 = 750A. I guess some people just don't have common sense and lack of knowledge nowadays.

this is exactly what i mean. it's been supposed more than once that some of the "high end" manufacturers and some of the "low end" manufacturers are all getting their packs from some of the same places and it's getting very difficult to determine what's inflated and what's real.
some day, there is gonna need to be a standard of testing these numbers.
example:. my lhs has stopped carrying one of the top battery companies because he said they switched manufacturers to save money and they have been getting a ton of warranty claims. he went on to say they used to be a very trusted company and now he wouldn't put one in his heli if it was the last battery on earth. so who do you trust?
