Battery

I'm building Javelin-powered rover. Powering it with standard 9v batteries would result in a very short run time. So, I purchased a 7.2v 1500mAh R/C type battery. Would this kind of amperage damage the Javelin Stamp Demo Board and/or the Stamp?

    No. Batteries can't force current into a circuit -- you can safely power a Javelin from a car battery, it will run for a very long time. The trouble with high-current sources happens when there is a short; since there is so much available current a short can quickly turn into a destroyed device.

    By the way, I have a cigarette-lighter adapter for my car so that I can power BASIC Stamp and Javelin Stamp projects while I'm driving.
