I just purchased AA [link=http://www.all-battery.com/index.asp?PageAction=VIEWPROD&ProdID=566]Tenergy[/link] 2600 mAh NiMH batteries for my digital [link=http://www.dcresource.com/reviews/canon/powershot_a550-review/]Canon camera[/link] to take photos of RC Airplanes.

I have both this [link=http://rocky.digikey.com/weblib/Panasonic/Web%20Photos/BQ-390A.jpg]Panasonic[/link] and this [link=http://www2.gpmd.com/imagel/m/lmpup9531.jpg]Multiplex[/link] charger. I'd like to use the Multiplex charger though.

To use the Multiplex charger, are there any charge leads or adapters that will allow it to charge two to four of these at a time?

If not, how hard would it be to make one up? Any suggestions are appreciated. Thanks.

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.

I sent an email to all-battery asking if they think that quick charger would work.

That battery holder looks perfect! Thanks. I wonder what kind of connector that has on the end. It looks like it might fit my Futaba charge leads.

On one end is a "banana" plug that goes in your charger. On the other end of one pair of leads (when you buy them, they come in pairs like that.. one for a TX and one for an RX) you have a typical Futaba type servo type (sorry for the redundancy) connector. In the case of that picture, I think that it is Hobbico...probably Futaba, but pretty much universal. No, looking at it, it says "EA"..whoever they are.. but it is just fine for this application.

As long as RED goes to RED, goes to Positive ( + ) on the battery and the BLACK goes to BLACK goes to the Negative ( - ) on the battery, or the battery pack.. you're all set.

If you look clusely at any typical RX battery pack, you will see four cells connected in series. The connections are 'welded' in place and done very quickly so as not to damage the battery internals with the heat. My telling you this is because the typical packs consist of the type of battery you are working with here... so it will most likely take a quick charge (1C at MAX!!! or no more than 2.1 Amps) and it will charge in one hour or a little longer.. (10% overhead so make that about 1 hour and 6 minutes or so). It is always best to slowly charge batteries.. 1/10C is just about right, and they will last longer.. but 1C will most likely work.

CGr.

Okay, thanks for the charging tips.

I already have the Futaba charge leads http://www3.towerhobbies.com/cgi-bin...&I=LXL332&P=ML

and just wanted to know if it'll plug right into http://www3.towerhobbies.com/cgi-bin...&I=LXFVC8&P=FR

Sounds like from what you said it should.

Yup. Should be just fine. Let us know how it works out. Just don't use the holder for flying glow, please!!

Nope, I would NEVER do that! I ordered the eight batteries so I'll have a revolving set of two at a time for the camera I have in my field box. When I shoot videos using it, they die pretty quick, and I want to keep at least a set or two extra on hand.

I'm just starting to collect videos and photos of airplanes from fellas at our field flying and visitors and will be posting them on youtube.com occasionally. I'm hoping once in a while someone will return the favor and get some video footage of my flying as well. I got my first solo on video as a matter of fact. I guess I'm kind of corny when it comes to some things but I like to capture the moments from time to time

I've got, like.. oh, four sets of four NiMh batteries and keep rotating them in the charger. It's a wall-wart type of thing. The whole thing has a plug on the back and the whole thing just plugs in to the wall. I like it because it will work in any country regardless of voltage and frequency. But, your idea is a good one. And should work just fine.

I've got one of those too. See my initial post up above for the photos. I sent an email to all-battery.com asking if it'd work and he said it should take 4.7 hours to fully charge four of these new batteries using that charger.

I know, why would I bother buying the battery pack holder then, right? It's because I figured for a few bucks I can use my Multiplex charger and give them a better charge, I'm thinking it'd be better anyway.
