I'll be receiving the 2W-2.4W version of this laser soon
SF501B 445nm Blue
It needs 2 16340 batteries and all I have are some ultrafires I have around that I bought off ebay or amazon at some point in time and I keep reading that they are terrible, don't put out the advertised mAh and such.
I honestly don't know much about all the different companies that sell batteries and i can't seem to find a thread with enough consolidated info on them. The questions I have is should I get protected or unprotected, what brand should I get and what's the best battery to get the strongest output from the laser.
