Here are some photos of my loaded DMM. The DMM is a cheapo that I got on sale for $5 from Harbor Freight. It is a tiny thing measuring 1.5 x 4.5 inches but I checked it against a Fluke and it agrees to within 1/100 volt at 4.8 volts. It also measures resistance, ac voltage, ac and dc current, etc. Real handy to have around the house if you don't already have one.

The load is a 18 ohm 2 watt resistor (color code brown, gray, black). This is suitable for use with a 4.8 V receive pack and will draw about 270 mA. I soldered stackable banana plugs onto the resistor, which are available from Radio Shack for around $2. I used insulated wire and shrink tubing to connect the bare wires coming off the resistor to the banana plugs, but this is not necessary. You could just as well put the banana plugs directly onto the resistor's leads. The charge jack is from Radical RC and comes with the banana plugs attached. I think it costs around $3.

The resistor is not polarized - it doesn't matter which way you connect it.
