MetalMan, do you know what the Ah rating of those M1 cells are? I'm hoping for 3Ah (or more). They might be less since DeWalt says there's greater run time, but that might be simply because it's using 36v so the current doesn't need to be so high. I'd like to use a 5s1p arrangement for size/weight/simplicity, but have found nothing on the A123systems or DeWalt sites that says exactly what they are...
