Batteries?

[Fierce Waffle]

Im confused as to what batteries I should get.
I bought this driver from Aixiz : 1W 445nm blue laser diode driver / 405nm laser driver, AixiZ

And this laser diode : HighTechDealZ - 445nm 1W (1000mW) Blue Brand New Laser Diode in Aixiz Module

I would like to buy some rechargeable Li-Ion batteries but I dont know what MAH I should get or what number(e.g 18650). Can anyone help. Explaining why I need what batteried would be helpful aswell.

That driver needs 3.7V. The battery you choose depends on your host. What host do you plan on using?
