CFX battery power

[Noyl Wendor]

Hi,
So its been a minute. I decided to get a CFX to install into my hilt that needs an upgrade. I am of course reading the manual (3rd time) now. As I see in the manual the part about power supply is not so clear to me.
So I would like clarity on this questions,
I may use a 3.7v or a 7.4v lit-ion battery as I wish, I only need to resistor it approiate?
I may do the above with a multi colored LED?

:)

Did you ever get your answer?
I was under the impression that you were correct in that we can use a 3.7 or 7.4 as long as we resistor it properly, but no one has confirmed nor denied this so I'm guessing it's true.

It will depend on what you are planning to use as the light source. You’ll likely be best off using a 3.7V 18650.
