Here we go again, it's all about an opinion somebody heard somewhere.
"a one ampere current in 1mm wire is moving at 8.4cm per hour"
From Science Hobbyist: http://www.amasci.com/miscon/speed.html
You can charge two packs in parallel, provided you keep the charge current low, the first pack charged will heat up slightly, increasing resistance, then the second pack will finish charging.
All told, buying two chargers is best.

As above, charging in parallel is a "No - No"
BUT you can charge them in series at anytime, regardless of state of charge of each pack. I'm not sure if it even matters whether the two packs are the same capacity or not. My logic says it doesn't matter when charging. The electrons will just run through get deposited anywhere along the circuit where there is room for them. Sort of like putting the water in at one end of the ice tray and letting it just overflow the first cube hole into all of the others until the entire tray is full.
Go ahead safely with this setup for charging. (don't get crazy on charge rate though, I would keep it down around the 300 to 400 mAh range)
However, I DO NOT recommend cycling the packs in series. Especially if the packs are not the same capacity.
If you rig an adapter plug, you can charge them in series.
- you have two 4 cell (4.8 volt) packs
- rig up an adapter that when connected the two packs will be in series. Voila you have an 8 cell (9.6 volt) pack.
- plug into your Elite. Tell it you have an 8 cell pack and charge away.
There you go, you are charging two packs on one charge port of your Elite. The second port remains free to take care of your transmitter.
The only trick is to rig up the charge cord properly. See picture. It is my sorry attempt at drawing with MS paint. (I'm an AutoCad guy). You probably have to right click and "save-as" to your computer and then open it in order to see it properly.

Hey Claude, thanks for the info. I was actually thinking the same thing. I havent tried any of this yet, I still dont have 2 packs hehehe. I am a Ham radio operator (general class in the US) and I also have some IPC and PACE certifications for electronic repair so I know quite a bit about electronics. I am studying Mechanical engineering and have spent about 3 years on Autodesk software - AutoCad, Inventor, and some Archetectural Desktop so I know what you mean about the drawing!!!!
So with the 2 packs in series.. just get two female plugs that fit the packs and wire those up in series - the negitive lead of the first to the positive lead of the second, then put banana plugs on the first positive lead and the second negitive lead. That should work.
