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.
