523nm Green laser module advice???

Hi, i was wondering if anybody has made laser using the 523nm laser module that looks like that from inside a leadlight laser.

Im getting im soon and i need to know what power should i run it at?? its a 523nm @ 180-200mW module. i heard that it runs on 3V, but dont know if you can use 3xAAA 1.5 lithum battery. so it will end up being 4.5V or abit more fully charged.
Is there any person on this forum making heatsink for these modules??
