    Lumintop FWAA Vampirism

    I have a Lumintop FWAA with 3x Nichia 219C. It's an awesome little light. Well, except for the horrifying vampiric drain. Way worse than mere parasitic drain. For example: four days ago I put in a Vapcell H10 1000mAh cell charged to 3.85v. It has sat on my desk since then, unused. Just...

    Variety is the spice of life

    So I'm a pocket knife noob, and a flashlight noob too for that matter. But I have enjoyed experimenting with some different knives the last couple years to see what might suit me best. Best regards, DJ

    A few of my recent knives.

    It seems like a lot of people like the spydiechef. What is it that you like about it so much, is it the blade shape that gives you hand clearance; or something else? I heard LC200 is a real top-end steel. I don't have any blades made of it or Maxamet, but oddly enough I do have one knife with...

    A few of my recent knives.

    Seems like you have quite the collection of Spydercos. Mind if I ask you the "if you could only keep one" question? Regards, DJ

    A few of my recent knives.

    I know nothing about custom fixed blades, and I'm not fond of Spyderco knives--but still I can appreciate that you guys have some high quality cutting tools here. Regards, DJ

    Automatic knives, valid for use?

    Yup, locally I can carry a 17+1 9mm and a .380 BUG and a pepper spray, but can't add a pocket knife over 2.5" to the mix because then I'd be a dangerous threat to society. Go figure. Oh, and the ironic part is I concider my pocket knives just useful tools for smallcutting tasks, not as...

    Bear and Son Bowie

    Nice, I like it. I'm tempted to get one just to have a classic US knife. What kind of wood? 12C27 is a nice stainless budget steel used in the Morakniv stainless versions. Regards, DJ

    Efficient way to discharge Li-ion to specific voltage?

    OK, I've been playing around with it and it is working great. Still doing some tweaking, since it seems that 14500 cells are harder to get optimize the settings for, while 26650 seem to be easy to get within +-0.02v. I'm very happy with the new charger so far, thanks for the recommendation...

    Efficient way to discharge Li-ion to specific voltage?

    Thanks for the info! I don't mind if the process takes more time as long as it is an automated process. I have already been playing with lowering the target voltage more and more, now I will try out this other method. If I understand correctly I can experiment with both and when I get them...

    Efficient way to discharge Li-ion to specific voltage?

    OK, so I got the MC3000. But either I'm not doing something right or it is a bit wonky. I put in four 14500 cells that were in the 4.15-8v range and ran the Storage function on them. By default I think it was set to 3.8v, but it only discharged them down to the 4.05-11v range. Then I set up...

    Efficient way to discharge Li-ion to specific voltage?

    Is the MC3000 $73 better than the VC4SL? Thanks, DJ

    Efficient way to discharge Li-ion to specific voltage?

    Cool, thanks for the info. I will check these out! Thanks, DJ

    Efficient way to discharge Li-ion to specific voltage?

    Hi, Yes, a charger that would do this automatically would be awesome! I don't consider sitting there manually babysitting the discharge of a dozen or score of batteries, one after another, to be efficient effort or time-wise. I'm looking for the lazy man's way of doing this--that's what...

    Efficient way to discharge Li-ion to specific voltage?

    Hi, I have a bunch of 14500, 18650, and 26650 li-ion batteries. I'd like to find an efficient way to drain them in batch to a specific voltage when I know I won't be using some of them for a while. Maybe 3.9v or something like that. I say drain because my batteries are more often above the...
