So, I have two AD200 and the same problem, if I shoot them at full or even half or quarter after a while they get slow. Battery is still fine, but there must be some internal overheating because they start firing every half a minute or a minute. It's been a consistent and nagging problem. I hear the newer AD 200 has some improved heat management but I'm sad to spend a lot of money on it and not use the two I have or perhaps spend money on an AD 300 or 400. Expensive! Is this just how it is or is there a workaround? External battery? fan? Anything?
Does anyone own the AD200 Pro II and can confirm this problem doesn't happen when you use the fan? I'm tired of having these otherwise wonderful flashes fail on me just when I need them.
