In the presentation they announced that they would have 5 times the capacity and 6 times the intensity of a 21700. If you take a 50E as a base we talk about 25Ah and 60A, if it were a 40T it would be 20Ah and 210A. Both very respectable figures for a battery that is the same diameter as the 3x 21700 and only a centimeter longer.
I can see how some people wouldn’t get excited about it. Ok, I’m lying, I really can’t. A new revision of a Q8- or a D4S-like light with that kind of capacity and current makes me salivate. I hope they live up to the hype and the EV market drops a few crumbs for us.
Worry about parasitic drain would be a thing of the past, at least.
How about an Imalent MS19 with 6 of those bad boys and 36 SBT90.2s
I’m thinking along the lines of a D18 or MF01S
You’re both making a very good point, and I agree, but I hate it. If there are 4680 lights, the first ones are going to be outside the range of what I consider “budget.” Which is probably ok, because the cells will probably not be “budget” initially, if they are made available to plebes like us.
I don’t by torches that cost over $100. I’m definitely going to take a wait-and-see approach if the cells cost that much, and I’ll be shocked if they don’t, at least early on.
It should lost LESS money not more. There are a lot fewer components to manufacture in comparison to a 3x21700 or 4x18650, and fewer points of failure.
Yeah, am I the only one who thinks Q8?
Yeh, I said that a bunch of times before already. You just need a few mm to bore it out and make it fit a single 4680[0] vs 4×18650.
And “flat” stiff springs like BeCu versions of belleville washers could replace coil-springs.
Pushing 60+ amps would be impressive.
That would make sense but I think most companies would set the price based on the capabilities of the light. If it cost a dollar to make but threw a million lumens 10 miles, it would cost thousands of dollars
Eventually, yes, it should. But, intially, when Tesla’s voracious appetite for them is not quite being satisfied, and they’re brand new and demand is extremely high, it’s not uncommon for a price bump to occur.
As have I. Most of the huge lights are way out of my budget.
But, a big light with a 4680 (when they’re $30 :money_mouth_face: ) and a bunch GT FC40 emitters and a peltier cooler might convince me to buy my first ever >$100 light.
Just imagine the size of the Maglites once they get their hands on them. I can see an updated version of this. 
Personally I don’t care how big the light is if I’m just looking for power. I’d want it it be probably 50 pounds or less (: maybe a ghostbusters design with a backpack full of 4680s
That’s pretty clear 
Yeah, I can see uses for lights like that.
A dive light with a battery pack on the belt with even 1 or 2 4680s could be great. Or a 4680 pack on the belt that powers your dive computer, headlamp, tethered hand light, and communication helmet. And heated drysuit. Awesome.
None of the above is my idea of budget, but still exciting.
I’d love a heated jacket that takes 4680s or even 21700. I have one that takes this funky proprietary battery that’s only like 5,200 mah and costs $60 or $70 for an extra
Basically, the 46800 sized cell is an increase in energy density by itself due to the smaller ratio the canister itself takes.
What makes Tesla’s 46800 special is that they have a considerably different chemistry setup that makes their energy density considerably higher than current classical lithium-ion designs.
Personally, I want a BLF GT with 2 of them 
Any 4 x 18650 light will be very similar in diameter to the 4680 - the minimum circle to fit 4 x 18mm circles is 43.5mm. Add a little space for clearance around each battery and you’re basically at 46mm
I made this post about a mythical 45650 cell for the LT1 (derived from the Q8, of course) before Tesla had given any hints of a 46mm battery. It accidentally led DBSAR on a wild goose chase, since the advantage in energy density for this kind of application of such a cell was immediately obvious:
I’d also be interested in a laser with a cell like this. The most powerful one I have right now is a 7 watt blue. Of course it would be limited by max power on the diode, heat…
