Hello

I just found on ebay 2 laser of 100mw++ red laser
the laser are looking like this

First


Second


They are arround at same price (15usd~), do you think those laser have driver
include ?They have a small heatsink but ..., on the spec the working voltage is 3.2
to 5.5v, will it be safe to use them with a 18650 battery ?

Thanks
