RE: Expensive US made vs Chinese Batteries
See it all depends what you would like to do with your setup. If you don't require the absolute power, then the cheapy stuff is fine. 50-50 Chance of getting a good pack. Thunderpower use to have Enerland cells, but Enerland doesn't make cells for the hobby anymore as of January this year. So no there is no point of spending big bucks with Thunderpower anymore. I use Acepow in my high current cars and use the same packs in my E-bike as well.
