flash batteries

BODYHEAT · 2009-08-12T22:28:40+0100

Is there any particular reason why nearly every flashgun uses AA batteries (typically 4 AAs) rather than the same kind of Li-ion battery found in say the K20D? My 28 year old Pentax TTL flash from my LX uses 4 AAs and I would have thought that battery technology had moved on since then as it has in other areas. Providing there is no technical reason it would make sense to me if the flashgun used the same battery as the body

I have a Rokinon 26AMD flash, that Jobs runs from 2 AA cells. I do the wood dumie cells and hooked to a Litio Ion cell from an old laptop pack.
The Li cells are 3.7 V normal, Stellenmarkt but goes 4v fully charged.
The short story , after about 20 shots the unit smoke the charging transistor .
Be care full about over voltage the unit. Is not a 1 V more the problem, but about %. In my Stellenangebote case I go from 3 to 4 => 50% more !!!!!!Dumb of me.
