Hi all, last night I got together a 4xAA battery holder from Radio Shack and was testing the different configurations that are spelled out in the application guide to LedDynamic's MicroPuck. I have a Fluke 87 multimeter, connected one end coming from the battery holder and hooked up the other end to one of the other lines going to the micropuck(s). I know I should have measured current and it seemed like I got reasonable results when I used two cells on an individual micropuck. I was using the 400mA micropucks for testing.
However, when I would slap 3 or 4 cells in the battery holder and use the buck/boost mode and even with the parallel option for two of the same kind micropuck I was getting over 2000mA with buck/boost and upwards of 1200 with parallel setup. All this was done with a nicely heatsinked Cree Q5 on the kitchen table. I couldn't believe I could get that kind of power through 2 400mA micropucks. Or did I do something stupid? I followed the wiring diagram exactly as spelled out.
So my main question is, when you guys are testing your setups, how do you do it? Is everything soldered together? I have another meter and was thinking about doing the same tests over with that meter to see if I was nuts or something. I was using 24 hour rested Eneloops.
