Hello all.
Being almost completely new to electronics and completely new to the lightsaber scene, I've been doing my due diligence and I believe I have everything correct here, just want someone to double-check.
Tri-Cree Single-Colour Stunt Saber
Extra Details:
PCB:
2.7V - 4.35V under/overcharge protection
8A continuous 15A peak current protection
LEDs:
Cree Photo Red ("Deep Red")
1000mA = 2.5V
Math:
Resistor Value = (Vsupply– VF) / IF
= (3.7V - 2.5V) / 1A = 1.2Ohm
Resistor Power Rating = IF2 x Resistor Value
= (1A)2 x 1.2Ohm = 1.2W
Disclaimers:
Yes, the smart charger port is on the side, exposed. My hilt design is dreadfully plain and needs something to add detail, though I will probably try making a dust cover for it.
I know a 3-cell battery isn't common but I have lots of room and the extra battery life will help immensely at those 3-day weekend cons. Also I found heatshrink that fits 3 cells in a triangle-pile just perfectly.
Questions:
1. The PCB for the (unprotected) li-ions has a +/- port for 3 x 18650 cells. Is my wiring here correct? Just connect straight to the PCB? I'm attempting to wire the cells in parallel for a total of 7800mAh, which should be 2 1/2 hours-ish runtime.
2. I guess that's the only specific question I have, just want someone with experience to double-check the overall wiring.
Thanks a bunch in advance
