NBv3 Need Resistor?

[brthegreat117]

Hey all. Since my Hasbro BS Luke ROTJ conversion was a bust, I'm doing a full conversion on this bad boy.
G/G/W Tri-Cree with a NBv3
Now I know that I can use .47ohm, .5 watt resistors, which I got with the formula.

But my question is, is it necessary?
A few smiths told me that I could run it fine without the resistors.
Would that be correct?

What would keep you from using them? Space?

My philosophy, especially when you don't have the means to measure the actual Vf of your specific leds is better to be safe. 1/2 watt resistors are fairly small and take up very little room.

You really should use at least a minimal resistor. Not everyone on FB knows what they're talking about.

I'd recommend using a resistor. It may not be absolutely necessary, but you're risking damage to a $19 part because you don't want to use a few $0.45 parts? Resistors are cheap insurance, and they don't eat up much space.

Agreed...if soldered and heat shrunk right there just an extension of the wire it self.

I was just confused that they didn't use a resistor for the wiring.
I'm still gonna use mine.
Finished my wiring diagram. Excuse the messiness. I have no artistic talent what so ever.

If I can get a confirmation that my wiring is correct, then that would be great. Studying paid off
Thank you fellas

Looks right to me. I'd consider tossing a resistor on your FoC die as well. Otherwise you may get odd behavior from the board during clash events, especially when the battery starts getting low.

Incidentally, when your saber starts acting strange (erratic swings, poor response, etc.) then it's probably time to charge the battery.

Awesome!
Will add that resistor as well.
Thank you
