RE: Batteries for the castle BL systems
I spoke to one of the techs at Castle today and they are really helpful. He suggested getting the best batteries you can afford as they are almost always the limiting factor with brushless systems. If you have questions about their products call them, they are really approachable and want their products to perform to their full potential. Excellent product support, at no time did they make me feel like I was being a pain, in fact I had a nice conversation about setups and batteries. Nice people to deal with.
