That is a lot less than the number I had in my head which I got from here: batteryshowdown.com/results-hi.html Which is with a 1A discharge current BTW. Unfortunately it does not mention if that is a continuous 1A or not (for example 1A for 1 minute and 1 minute 0A for the battery to recover). That could explain the difference. | |

This would also explain the massive heat build up. At 1.5 amps discharge rate, your alkaline AA won't last long at all. You will need a different battery chemistry or try C or D battery. Thermal isolation is certainly a good idea. | |
