I hope im posting in the correct place. Sorry if not. Could anybody help me with my new Saik laser build. It is a 3 cell host (14500) an xdrive set at 3.4a with a 6w NUBM44 diode in 12mm module with a g2 lens. It only worked for a few days but low power it flickered once and dimmed way down now it has no power at all with no visible beam. What has happened?
