I just received the PICAXE 8 Pin Proto Kit from Sparkfun (yay) and it comes with what looks like a 9v battery snap clip but the datasheet says that I cannot use a 9v battery. The text states:
"ONLY USE A 4.5V or 5V battery pack, not a 9V PP3 battery, as the power supply."
So what kind of a 4.5v or 5v battery packs uses the snap type connectors?
