Great quality, amazing customer service, speedy fast delivery.
Two buddies have ordered on my recommendation and they too are pleased.
I will use Progressive RC for my future battery needs.
- Running this in my 450 pro with a 2221-8 and they are the best performing when you look at the data logs out of the ice cc. When I first looked at Sypder Batts I was a little worried about the C rating being lower than other batteries but I from experience I would say those other batteries in my case have "puffed" c ratings cause these come down cooler and out perform all of them!
