SB-28's (external power)

[jedtrently]

Thanks Jeff. However yesterday I could turn on the flash for a little while with newly bought battery. Then I fully charged the battery today and tried and then this happened. How to decide whether inserts are in right holes properly? Here is a clear figure shiwing the holes.15894733099786648542138879892425.jpg

Hey buddy,
Yongnuo 560 flashes you have to mount the batteries in the lower 2 terminals only so I'm pretty sure if you find the 2 correct terminals your problem will go away

Did anyone consider using a Nikon SD-8 or SD-8A Battery Pack together with a SB-28? (A=European market, with different power plug) According to the SB-28 manual the recycling time will thus be shortened from 4 to 2.5 seconds, full power recovery. The pack holds 6 AA batteries wich looks like some xtra power although the remaining 4 in the flash get a different function: 'The Speedlight itself should be fitted with four batteries as per normal as these will power the Speedlights electronics - LCD, zoom head etc'. So, not the dreamed power extender but the short recycling time nevertheless is appealing. What do you think, is it worth buying one?
