I have been searching on the Internet about which battery is recommended for the Ft power pack B without finding anything so I decided to ask about this. I currently have a 3s 1000mah 35c/70c burst battery.
That battery should work well enough for that motor. You could go with something like a 1300 or maybe a 1500. I know it is a little bit more powerful than the original blue wonder. I have one of those and it runs my bloody wonder mk3 for about 13 minutes with good power. It will probably give you a solid time of about 9 to 10 minutes. I am guessing, anyway. If anybody would like to correct me if I am wrong, do so please.
