Using the right batteries

[isaacpeh]

Hello all! I've been here for awhile now . I was wondering a lot about what kind of batteries do I use for what drivers . I heard if too much voltage is being emitted , it would fry the driver (and the diode??)

So the question here is what kind of batteries do I use for what kind of drivers . And how many batteries do I use ? How do i not fry my driver?

Let's say I use a 2.2A xdrive driver . Is it okay to use 2 x 18650 ?

I know that xboost only require 1 battery.

and what does '18650' and other numbers mean?

I did some searching and couldn't find results similar to my question.

18650 is the battery size. if you search battery size, you should see a link which explains the different numbers.

Let's say I use a 2.2A xdrive driver . Is it okay to use 2 x 18650 ?

it doesn't just work with 2x 18650, it can also work with 2x 16340 and other 3.7v rechargable battery

thanks marcuspeh! that explains alot.

So now how do I not burn my driver ? is it fine to use any 2 x 3.7V battery to any driver as long as its not a boost driver ?

It depend on your diode. Red and ir only need around 3v and violet and blue need more than 4v. If the driver is a boost driver, it can only be use for violet and blue diode. If it is a buck driver, it can be use for all the diode. Lets say the diode need around 3v, 1 battery is enough. If I needs 4v or more, u will need 2 battery.

Don't forget green 520nm diode, they need a boost driver if using one 3.7 V (they charge as high as 4.2V) battery, 7 to 8 VDC output from the driver for that diode.

Replied to your PM about this. :beer:

The answer is different for every driver.
What you do is enter the name of your
driver into the search box and then peruse
the forthcoming results. So for your
X-Drive example, you would enter
"x-drive". Beyond that, if you are unable
to figure out what happens when you connect
a couple batteries together, then you need
to educate yourself in some basic
electrical principles.

Anyways thanks guys for all the fast and useful answers
. xD

I'll be building my first laser soon if my diode even passes through the custom (Probably not a too DIY one)
