I was wondering if it is possible to build a high power laser that is ran off of a 12V rechargeable battery pack? I was thinking of something like a 2W or higher laser in the form of a block/box not really a handheld. The laser wouldn't have to draw full 12v at a time, as this would make it have the ability to have a longer run time between charges but I was wondering if there is anyone that could bulld something like that? I already have a 1.6W handheld from a member here on the site. Thanks for any and all replies/help. :thanks:

Yup, easily possible. The X-Drive can run off 12V no problem.

Well, ideally you would use one x-drive for each diode as running them in series would mean you need 10V to power the diodes, or in parallel with a 4A x-drive would require bulky limiting resistors for each diode.
And yeah, it's easy enough to make dual diode lasers, especially if there is room for adjustable mounts.
The price of a dual diode diode laser is double that of a single diode laser, and 100-300$ more for the optics to combine the beams. Edit: That price is with a waveplate.

You are wayyy over my head on the technical details. Well I see that you are able to build it if properly motivated, so if you're interested then send me a pm as a price range because I really do want one or more for test purposes. Or if you know of someone who can build it then please let me know.

It can be done.
8.4 VDC is all you need with a "buck" driver.
A portable Lab laser with 650nm Red, 445nm Blue and 532nm Green primaries.
It is powered by two #18650 3400mah Panasonic cells for run times of over 2.5 hours.

Don't confuse voltage with capacity. A 9V battery for example will be vastly inferior to an 18650 cell for total energy storage. Drivers are usually more efficient if you have a supply voltage that's close to the load voltage.
One problem I see is that the driver will drain the pack until it's past dead. This will damage most battery chemistries.

Cyparagon wouldnt this last longer than 18650 cell(s)? Also wouldnt the on off switch get around the driver draining the cells?
