Well honestly I was hoping he has them on stock if he’s promoting them, not Sept. 13th. I’ve always awanted to try 10+ amp powerizer or moli cells. but if it’s shipping by snail mail I woulda added 5-10 more bucks. You kidding about Guam right? lol.
Will these work in the Mag with your Triple XM-L2? One at a time of course. You made reference to them frying 3 XM-Ls in direct drive, should I not use one of these? Or would I have to add some resistance? Am interested, just don’t know if it’ll cause more harm than good.
I need to extend out the delivery date from 9/15 to 9/30. I do hope this does not present a problem to anyone. I will be placing the order for the batteries by end of this week, might have them by 9/20, but, sometimes customs can hold things up a bit.
I may be interested in 3-4 myself but not at this time as money is super tight. It really depends on if they will fit in my TR-S700 as it has been modded to direct drive in high and the high amperage of these would really let the 7 LEDs in the light pull hard from the 3*26650 parallel cells. 70mm plus another mm or two for a contact nipple might be too much for the light. I will have to measure.
USPS has restrictions on Lithium batteries, but UPS, Fedex, DHL, allow shipments of Lithium Ion non-primaries, in international shipments. I don’t know what or if the restrictions are for primary Lithium batteries, but I never buy this kind. Anyway, not buying these from China, but from Canada. Mainly I’m waiting for enough orders to come in to cover the costs, and/or, sales of some more flashlights.
I always wondered about that: How come we can buy Lithium Batteries from China / Hong Kong, and they ship by USPS mail? Never questioned it because I was glad to get the batteries, but, just wondered about it?
Shipping domestic is fine with USPS, but supposed to put labels indicating Li-Ion non-primary batteries. And then, it’s slower than a boat to China on land.
Most flashlights SHOULD accommodate for variances in 26650 battery length. Some 26650’s with protection circuitry are pretty long. If the battery compartment allows for 2100mm +/-, should work. Might be able to mod the tail cap, etc. One inch is about 25mm.
Also, these do not have a nipple, but are flat both ends. However, the flat on the positive end is slightly raised, and these batteries do work in series. Always make sure all batteries are charged evenly, as one dead cell in with fresh charged cells, as with any Li-Ion, might cause a fire.
These batteries make a huge difference in direct drive applications. You’ll have to watch the power level. Putting one of these into Big Bruiser direct drive will fry the LEDs pretty quickly. I always put in about .1 ohms resistance into Big Bruiser, or, about .5 ohms into flashlights with LEDs in series. Always watch for a shift in color towards blue. If you see even a slight shift in color, shut it down, it’s probably damaging the LEDs. When the LEDs go south, usually it’s only one that dies, I think it’s the first in the series that blows. To use the 26700A, you might need to add a bit of resistance back in, or, maybe if you use Sinkpad boards, it might be able to sink the heat?
I finally made payment for the batteries. Thank you to all who have already placed and order, and are being patient, and also, to those who will hopefully also order some of these batteries. I should have these mid next week some time (assuming customs does not hang things up). Usually the shipment goes smooth and is timely, so at this time I do expect to begin shipping your orders before the end of next week.
yes, quite a few have tested both sinkpads and Noctigon boards. I believe the limit on an xm-l2 was about 9a being sensible.
I’ve got three noctigon mounted dedomed xm-l2’s in series with a direct drive on high driver. I’ll be testing with a meter before I unleash it but I doubt I’ll see 9a/emitter, we’ll see I guess.
Yep, POOF would be easy to do with an XML direct drive with these on a standard aluminum MCPCB. I personally have tested XML2 on a 20mm sinkpad inside a flashlight to over 6000 ma. At 6 amp there is still a positive return on output at the 1 minute mark with good heat sinking. Above that your not gaining anything really by driving them harder.
