I have a sneaking suspicion that if you > made the battery pack (5 batteries), and put them under a 30mA load (160 ohm > resister) then you'll find it almost exactly 6 volts. I measured a loaded NiCad with 330 ohm resistor. 1.34 Volt. The responses on my question have been very informative, so far: - watch out for 4.5 - 5.5 PICs - don't use NiMh - include some reserve for self-discharge - consider a low-dropout regulator - consider a DC/DC converter I am now looking into using an LT1301 step-up converter, the cheepest one I can get (I'm aonly a hobbyist, so I'm limited to what the local shops offer). The nice thing is that I can now compare batteries just on a money-per-Watt-hour basis. Suddenly a 4 V lead-gel accu looks good, much cheaper for the same energy that NiCad. Thanks for all the tips!
