Best way to wire multiple laser modules
This laser has a driver included, as the datasheet only gives a voltage rating for the supply (3-5V).

The laser is given at 5mW, but this is the optical power output.

To know if you can wire those laser to your battery, you need to know the power consumption of the laser, and it seems it is not given by the seller.

Thereof, you should measure the current yourself, just connect one laser to the battery with an Amp meter in serie.

Then you simply need to multiply the current by the amount of laser and see if it will be supported by your battery output.
