Thanks GSS. Yeah 26650 is great for the higher power diodes we have out there. I found some round boost drivers that sound promising on ebay. Waiting for them to come in the mail. After I do testing and if they prove to be what they claim then I'll start including them. Here's hoping!They will sell soon..
The 26550 cell capacity is nice selling point..
Of course I am interested ... but first I have to learn how to build one from myself ... I already have many 303 reds ...It's a personal build. It has an m140 in it so not too powerful. It has an astral driver I was testing with. Eventually the diode is going to be replaced with a 1 watt green diode. Interested in a kit?
