Comments about Lumedyne HV Ultra Megacycler for Flashes - Extra Fast:
Work as advertised. I now have four of these batteries to power four 580EX II speedlites. AA batteries give a speedlite a 3 second recycle at full power... the Ultra Megacycler drops that time to one second or so. Makes a slight recycle whine (that the 580EX II does not). Batteries did arrive exhausted suggesting that they had not been charged monthly as the directions indicate is needed for best lifespan. Wish it came with a strap. Otherwise no complaints - except - for the incredible !*&^#$%@ high price!

Nothing is worse than having a photo job and looking at the battery indicator showing low and the bride is walking in the door. What can I say!
Alkaline batteries good, rechargable batteries Better, external power supply BEST.
I use the lumedyne pack to help power a Nikon SB-900 fired remotely or on the camera. It allows for faster recycle time well beyond the capability of the flash unit's 4 batteries.
P.S. Remember, you get what you pay for. Price is a factor but when your flash unit will not fire because of low batteries, the excuses pale to a bride's response when she realizes you did not get a critical Photo on her very important event!

At last I have found a product that keeps my flash firing all night and saving the environment from all those batteries I seemed to have collected. Never had much luck with rechargeable batteries as there is always one that seems to upset the system!
