If I remember correctly, Castle did have batteries at one point. Dunno what happend with that one. A123racing/Enerland is out of the hobby market. Not enough sales to justify that market sector. Acepow had a good chemistry, untill the bossman screwed up. So all that there is left is Hyperion as a quality pack. And how many people will really spend big money on a battery pack, when they can get the same capacity for 50% less. Not many, I'm guilty of that one myself. So in my eyes, it will be a gamble for Castle to make any money in the current USA market.

My 4s Acepow packs have a cell resistance of 0.9 mOhm on average when charged at 30A. At 40A charge rate the resistance doesn't register for a 1p config. That is not bad at all for a 67 dollar pack, considering the A123's are at 8 mOhm. Difference is that the A123 can put out some serious amount of Amperage in an instant. More then my logger can record. But you can see the difference in RC's. My GTP for example has faster launch on 4s2p A123, compared to the 4s1p 5000mah Acepow. The Acepow will have a greater topspeed, but in a dragrace it's too late.
