I had this exact same thing happen with the SST version. I selected the wait option (selected the latest date as possible) and it shipped the next day.
Mine shipped, it said it was backordered a couple of days ago also. I’ve been sticking with the wait option and so far all of my back orders have worked out within about a week or less.
People said no earlier. It only comes with an 18650 sleeve. You typically don’t need a sleeve with a 21700. If you do need one it’s easy to use a piece of cardboard.
dont use 21700 cells… they are too long and will compress too much on springs… atleast on 2 different batteries it doesnt matter i tryied, u are not supposed to use much force to screw down a tailcap…
Sorry mate just seen this now. Dome slicing on flip chips LEDs is okay because you don’t have to worry about bonding wires. The LED inside my FT03 is not dedomend because i only bought 4 and have sliced 2 others already. Ill try and put a sliced XHP50.2 in there and see how it goes. The stock MCPCB is wide its 26mm i think so you can fit a washer around the LED easily enough and use that as guide for a straight cut. I’m not sure how low you can go but i used a 1mm thick washer and i went lower than that after.
