I would never go higher than stated, its too risky. What you need is 6.5 volts REGULATED DC with ~ 1 amp current capabilty or the flash will take longer than normal to charge. the problem with UNREGULATED supplies is that they often have too much voltage rise under no load or small loads if they have good full load current capability.
I made a small 6.5 VDC regulator "box" that goes between the higher voltage batteries (9.6 VDC Nimh RC battery packs) and the istDS, works great, and won't damage the camera from too high a voltage. I would give you my simple schematic but I wouldnt want to be liable if something went wrong for you so I wont. jco -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of J Sent: Saturday, April 21, 2007 1:42 PM To: [email protected] Subject: external battery source for ist D Has anyone played with or used an external battery source for the ist D. The side of the came has a plug for external source and it says 6.5 volts. Do you think 7.2 volts would be to much or the other way with a 6.0 volt external source even though it says 6.5 volts..The internal battery source is 6.0 volts.I am thinking of making a external source......Any thoughts ?????
