Ahh, I missed that in the tech notes. My bad.

I use the Hobbico Quick Field Charger MkII:

It's DC only. I connect it to my car battery and charge my stuff at the field next to my car. When I use it at home, I have a Radio Shack 15 amp 13.8V power supply that I connect it to.

I also recently purchaged the MRC Super Brain 989 charger:

It comes with its own AC power supply, can be used off a 12V DC power source, and will charge almost anything.

Somebody out there must make a good AC/DC NiMh charger that will charge 2 batteries for less than an arm and a leg. I know the Super Brain 977 charger will do two 3000Mah 7-cell batteries, but it's pricey at $95:

The 977 comes with the same AC power supply my 989 comes with, and will do battery cycling (automatic repeated charge and discharge), LiPo cell charging, and some other features you may not need. On the other hand, who knows what you might want to charge 18 months from now? If you don't mind spending the $95, the Super Brain 977 will do everything you want.
