Well, i managed to blow up another one
It worked fine with a bench power supply too :(. On the positive side, i think know how this one happened, so i shall buy a third one!
What the hell!?
I think my positive wire soldering technique bent the pin over when i put in the battery so it shorted off the inductor (i think)
You’ve been soldering them wires yourself?
Put a piece or two of shrink tube on the pin before you start soldering.
Or get the wired driver this time 
The inductor is hooked to the positive wire through a via on the pcb going straight to the ring where the spring is soldered on, also that whole hole is a via for the positive. There’s no short there. Did your positive wire touch the body?
I dont think so, it ran from my power supply hooked up to the shell and positive pin for a while without problems so i reckon it was putting in the battery moving the pin and spring that caused it. I just cant see where it could have shorted.
Was the reflector installed?
Could the reflector have short to the Wires on the MCPCB?

It was but it ran fine with the reflector in when powered from the power supply and i made a gasket out of plastic to keep the reflector off the emitter after i damaged it the first time
1 Thank
No scorch marks on the reflector?
2 Thanks
No and none on the emitter either
Do you happen to have a pic of wires soldered to the mcpcb?
The damage resebles a direct short and I’m trying to figure out where it’s happening.
I desoldered it unfortunately. The joints looked fine but i cant rule a short from there out. Surely testing it before adding the battery rules that out though right?
How many amps can your psu push? Can it melt the driver? Will it do 50A?
It can do 0.5a. Tbh im not an electrical engineer but i assumed that the led lighting and the pcb staying cool up ruled out a short. I forgot to mention, when i put in the battery the led didnt light up at all
