The 250 spec pertains to current NiMH battery packs. Original ni-cad packs were in the 150 range. Following URL has some discussion on ni-cads: http://www.ikelite.c..._sscharger.html

Explanation from their electrical engineer:

If someone is shooting with dual strobes and want to power the system down, they should turn both strobes off. The secondary strobe is sending a small amount of current through the green wire and trying to power up the microcontroller but cannot provide full current, so that can result in erroneous operation. The only solution is to turn both strobes off. There is simply not enough room in the housing to provide extra circuitry to prevent this from happening. The housing was not intended to be used with the secondary strobe on with the primary strobe off.

I have run both Canon and Nikon TTLs on very low (virtually dead) batteries and never had the camera lock up due to the low battery. In those cases I was using a single strobe. So it does seem to be an issue of dual strobes, with the secondary powered up without the primary being powered up, or with the primary having a dead battery.

The person with the D200 freezing up may have an issue with an older chip, where the freeze up would happen when the meter turns off. They may have sent their housing in before we knew what the root cause of that problem. Our camera would not ever freeze up, and it wasn't until Karl Dietz sent his camera in that we were able to duplicate the condition.

I see we never got beyond being a "minor manufacturer" but the latches we use is why we started making underwater camera housings. To my knowledge, everyone used wing nuts in that early sixties era, and I was looking for something to make that I could use those fancy spring loaded catches................

I am worried about locking up your camera after taking a picture with those antiques from before digital era began. Make sure Subal provides center and ground contacts only from the camera hot shoe so you don't need special sync cords or need to cover camera shoe as described in following URL:
