cool, thanks guys! I was just concerned since if you use 2 AAs (or AAAs, etc.) with different charges one'll explode.

ok, so maybe it's a given that you shouldn't have 2 different amp batteries on an x2 tool (ie. have a 4amp and a 2amp on an x2 sawzall). But I was thinking that would be really convenient if, say you were using a drill with a 2amp battery and a 4amp on your multimaster and you needed to make a quick cut with your sawzall but you don't want to go back to your truck to get it, could you just use those batteries you have with you without worrying about damaging the tool/batteries? And maybe it would only be fine if the batteries and Tool both had star protection, thoughts?
