Hi!
I need a driver for a 100W LED - driven by 3 KingKong 26650 cells.
So -> In: 12.6V - Out 3.5A ~34V
Build-Thread: My 2 beefy (75W+) projects (Lots of pics, not finished)
I have one of these laying around here: Page Not Found - Aliexpress.com and was thinking about using it with my flashlight.
I would change the CC Multiturn Poti with a singleturn and make it reachable from outside. The two TO220 parts will be glued onto a cooling-area and the two capacitors will be changed with good ones and layed down or fitted somewhere with short wires.
I will measure the CC Poti (Original 10K Ohm) for the Ohm when giving out 3.3 Amps and buy that one (If the Resistance is, lets say, 6KOhm - Can I just use a 5K Poti + 1K resistor in Series?).
So - does this work or am I missing something?
Thanks!
Felix
Edit: I knew I saw something like this: https://www.youtube.com/watch?v=c—5c3Egv4E
Can I make it like he does (just with the Current-Poti) up from Minute 4 ?
