I have gone thru the threads for SMC and ThunderPower and unless i missed it .Neither of them list who actual makes there batteries.Smc batteries just say made in China.This shouldn't be a big secret because i am sure that the battery company makes batteries for other companies .I would like to compare price and spec to those other companies .
So if someone knows who the actual maker is for SMC and ThunderPower batteries please post it or PM .

I think there is a lot more to it, beside who makes them. There are issues with testing and QA. I am sure all the batteries are produced by the same process, but not all of them can achieve 50C. You need to sort them out, and get the best quality.
