Laserbtb battery question

Hey guys,

After purchasing a few cheap ebay lasers ive just bought my first high quality laser.

I decided upon a Laserbtb 1600mW PL445 however im a bit confused at which battery to use. The info on the laserbtb site says 2x16340 however the manual on the same page shows 1x18650 and the picture of the charger on the shipping page shows what looks like an 18650 charger.

Can anyone who has this model please confirm which battery type it uses

Thanks

Trac
