We are certainly glad you put the Multiplex Charger in the post. We would not like to upset the apple cart by having a non-RC related post, now would we!! [>:]

If that charger will charge that single cell battery, go for it. There are several adapters that you can get somewhere, probably Radio Shack, that you can mount the battery (s) into and creat a battery pack to charge with that charger. I don't know what the limitations are with that charger.. four cell packs for instance.. would limit the thing to a 4.8 volt four cell pack (duh). But, looking closer at the picture you included, it does say 1 - 14 cells, so I would have to assume that it would be alright.

The below link with Tower Hobbies shows a four cell battery holder so, as I mentioned, I am sure you can probably get one at Radio Shack. You can either make up an adapter to work with the lead on the holder or go to Tower again and get one of these:

One small note.. you would not want to use a battery pack like this on a glow powered aircraft, and would really, seriously, not use one on an electric powered aircraft either. The vibration could really cause problems with intermittent connections to your receiver and you really don't want those sort of glitches. This is fine for a camera, but probably not a good idea for an RC aircraft.
