Hi, sorry if this was discussed somewhere else already, but I'm looking at buying my batteries on Ebay because you can get way better bulk deals with chargers. Anyways, Since there are so many different ratings of 18650 batteries, and I'm new into this game, i was a bit overwhelmed. My question is, for something like a 405nm 400mW Violet Laser Pointer, can using a higher mAh battery like a 3000 vs 4200 cause problems with the laser, or would it just have a longer run time? Also, tab or no tab?, protected or unprotected?? Does it matter?? Iv been pretty much educating myself off this site alone hahaha :thanks:
