Since my Nichia 9mm (3.5 W diode + 4 Amp Buck Type Driver + G-2 Focusing lens) in a copper heat sink (housed in a large aluminium flashlight) run out of order, I'd like to replace it with a MX900 with SXD Driver 4.5 Amp to peak 6 to 7 W, as you describe in the topic http://laserpointerforums.com/f65/7-watt-nubm44-mx900-build-94912.html
Some questions :
1 - You use two eFest 2500mAh 20A/35A batteries. Do you think the MX900+SXD dirver would support a couple of Ultrafire 26650 7200mAh 3,7V ?
2 - Wich provider could deliver a MX900 and other components ?
3 - Alternative : do you build it for people who ask ?
4 - Ca you give a price estimation ?
I'm a photographer, and I use it to align long distance lenses, so It's important for me to replace it.
