I recently came across a deal on a Blad outfit, this was the topic of a thread in the equipment forum. I also won a Blad 500EL on ePay that seemed to work well. I was a little concerned about battery availability. So, I took the battery box/motor housing off and applied a hack saw "(gasp)" to it, and installed a 4 cell AA battery pack. The connector I used will also let me use a 9 volt battery instead of the 4 cell pack. It works super, and still charges with the standard charger. The standard battery is still usable if you so desire. If anyone is interested, and maybe a little crazy I can walk you through it. I only had the nerve to try it because the 43 year old camera was very inexpensive. In a couple hours and with a hack saw, Dremel, and a steady hand you can use AA penlight batteries in your EL. P.S. I posted this here as I was afraid someone trolling trolling through might see this and ruin a perfectly good camera. If it should be moved, please feel free to do so.
