RE: Expensive US made vs Chinese Batteries
I've spent a huge amount of money over the last few years on Lipo battery's and can tell you that they all are all pretty much the same.
If the manufacture or Company selling them is truthfull about what they are offering you. It's very easy to market and sell a undersize battery to the unknowleadable modelist
What I've found is the Battery support after the buy is the most important. Yes you will pay more for Thunder Power product but believe me they have the most truthfull marketing program and will back up what they sell.
If a Thunder Power battery fails it will be replaced by Thunder Power for 1/2 its original cost no questions asked !!
I just tossed (8) 5000 , 6S , Hobbyking Nanotech's as they would not cover them under there 30 day warranty program , as they were out of warranty by a few days..
So, if you want someone who cares about us and our Hobby Thunder Power in my book is a class act period !!
Its the same old deal , " Pay me now or pay me latter"
