About laser which I want to buy.

Laserbtb charges shipping, so you need to account for that. Also, you shouldn't get those glasses, get an eagle pair from survivallaser.com.

Your eyes are worth $40 don't you think?

As for 16340 batteries check out AW batteries or IMR bats. All good quality.
I don't know too much about batterie....Sorry

As for a charger get a nitecore intellicharger i2 or i4. Awesome chargers.

Now that I think about it, your $150 budget Is unrealistic...

Fyi shipping on the laser will be at least $20. Same with the glasses since those ship from the usa ubless you found a international source.

Said it many times before, get the eagle pair I'd you care even 1% about your eyes and vision
