Don’t always trust those “*fire” batteries…chinesium ratings and all that…I like the purple efest ones…they usually do pretty well and are good batteries
Now you gotta learn to solder the button on the flattop batteries (pretty easy if you scuff the contact and use plenty of flux)
I have let the light run for a few min’s and it’s fine at full power. it does start to get warmish. I’ll have to tun it on and just let it run see at what point I can’t hold it anymore.
After doing some research I think a better option would be going for a DSOD-323F package DDZ4V3BSF-7DICT-ND the size measures 2.50mm x 1.25mm. The cap this is going on is an 0805 so that is 2.00mm x 1.25mm. and just for reference the MMSZ5229B-FDICT-ND that is the SOD-123 is 3.65mm x 1.55mm I have not ordered the “DDZ4V3BSF-7DICT-ND” yet but I plan on it, to double check the size. So if someone is going to do this mod I would order a couple of the “DDZ4V3BSF-7DICT-ND” they are only 0.17 cents
Question…. Should I be using the QLITE 6V+ Zener Mod driver? Or should I be looking at the FET boards for this one also? Not 100% on how the FET boards work.
