This is one of the newer "HV"-type RC controllers, which means it is good for up to 12s LiPo setups, which is 50.4V, fresh off the charger. I have personally used CC's HV series controllers with 15s a123 setups on RC helicopters, but I haven't yet tried a 16s setup. I will this week, though.
Don't know about these Turnigy models either. It would certainly be good to know.
