Arg.. Flat top IMRS, which side is positive?

[WageSlaveEscapist]

Got these EH IMR 14500 600mah batteries for my 5v box mod. They aren't labeled as to which is positive. One side has a lip, the other side has a bigger diameter metal cap. I can take pictures if needed. Frustrating.. thanks for the help

Thanks very much, just what I thought. Can't wait to put together my bottomfeeder!!

edit: Just had the most horrible experience soldering 510 battery connectors.. Pos soldering iron barely melts the solder, and not with the tip of the iron. 6/10 burnt fingers, burnt my shirt, two hours later I finally have some dangling wires and a switch that works. That was terribly unpleasant.

Just a heads up on the soldering, if you followed these steps just ignore this post:

Soldering stuff goes much easier if you clean the surface to be soldered very well, then rub some flux on both pieces to be soldered. This will allow the solder to flow much better, and you'll get a superior connection with less solder. It's surprising what a huge difference cleaning and applying flux can make. Hassle free soldering.
