@Ekstasis, what Nitecore is saying is absolute crap.

Not only is the Samsung 48G 21700 a 10A cell in a 30A light, meaning they cut costs, but the 30mOhm contact thing is quite crap.

There have been sub 10mOhm springs for a while now. They just wanted to justify putting a non replaceable incapable cell inside of a flashlight for cost-cutting and profit making.

The 40T wasn’t out yet when they made they made the TM10T. This is the problem with irreplaceable cells. The P42A cell that was recently released would have been perfect for this light.

Well I guess we will have to wait and see.. of this will become a thing yet, so far nitecore TM10K is the only flashlight with non replaceable battery that I know of .But I read now it has a normal 21700 cell. anyway They claim they get more power out of it of having it irreplaceable.

People are not dumb and don’t mind built-in battery for devices below 40$ but when they are seeking durability for devices that are above 100$, generally people are thinking twice before buying it. For someone who is following the e-cigarettes trend, it’s all the more obvious. Things/trends are moving faster than on the flashlight market. There is a bunch of small and med size devices with built-in battery but most generally with a much lower price than bigger, more powerfull devices with built-in batteries, which are rarer.
Removable 18650/21700 battery’s devices are plethoric.

Nitecore could have weld (tab) this new battery in a sealed flashlight. Why didn’t they ? Probably because of complains from enthousiasts about the previous version or because they know that a built-in battery for devices with a significant price is still “shooting a bullet in the foot” when competitors don’t generalize it also.

EDIT : Sorry, I pictured it differently in my mind and thought you were saying that the new one will work with a removable battery.

i thought gold doesn’t oxidize. why not use it?

That’s not the problem.

Trying to push 30A through springs is a very, very difficult task.

Honestly, I have to say Nitecore was both lazy, greedy, and impatient in this regard.

Why? While they are right in regards that the springs would oxidize, they didn’t tell why

Well, at 30A, any normal spring would melt pretty much instantly.

Here’s the thought process Nitecore probably had:

1. Let’s use gold plated steel springs. Oh no, they failed at 6A.
2. Let’s use gold plated dual steel springs. Oh no, they failed at 9A.
2. Let’s use dual phosphor bronze springs. Oh no again, they failed at 18A of continuous use.
4. Well, nothing on the market actually exists that can handle the load of a 100-120W light running off of a single cell.
Let’s put a 10A cell in a 30A flashlight and weld nickel plated copper strips instead.

If the engineers, or rather, Nitecore, actually put in effort into designing adequate contacts, they should’ve just looked at BLF and see what members cooked up in spring design.

They could’ve used dual gold plated BeCu C17500 springs, and they would’ve worked quite well if they had waited for a 25-30A cell.

Well, you’re right.

The gold plating doesn’t oxidize. It’s just that the springs fails first Smile

Why do people always think conventional?
You just need not the spring to conduct the current!
just use the spring to push the contact against the battery, you could use the same sort of contact like for spotwelding just with a bit raised button

Lumintop did it here

But wasn’t there a bunch of lights that failed in that run? Wasn’t it the Odl20c?

Or use a springless contact. Like DQG.
In a constant-length light that doesn’t need daily cell swaps (like that Nitecore) one could use a contact screw.

BTW I haven’t seen that Lumintop contact. Looks like a professionally done spring bypass. Smile

It’s nice to have the thread back on track with your CuTi E07 pictures but without a TLF account we can only see thumbnails.

@Lexel, I do know about leaf spring contacts.

I’m just saying Nitecore should’ve used a better solution than making an unreplaceable cell pack.

I have zero interest in this Cu/Ti E07 after being totally disappointed in the D4 Cu/Ti. The D4 gets blaz'n hot in a couple seconds - pretty useless unless you got thermal protective gloves to operate the thing with. Sure, copper is great for thermal transfer, but there's gotta be a better way to use it, like wrapped in aluminum maybe, I dunno.... frown

CRX has wrapped his triple in titanium. Which didn’t work well. Then he replaced that with carbon fibre and is happy with the result.

@FireFlies, anything else in the pipeline you want to share? A refreshed E07? A new light?

Yes, luv the pics - great job!! (should have said so before... frown)

I do luv the look of copper, but an E07 with all that power is wut scares me - least alum the rest of the light maybe?

Yeah I was looking at that too. The price is right!!!

But somehow I don’t think Fireflies actually means to give these away for free. Ughh

I am not a big fan of the Clear-Anodize aluminum, a flashlight should not look too bling bling it should look cool also..for me as a security guard this would look to bling bling being on duty.
However black with copper head would look better, better contrast also…

I guess we will have to wait and see if this is aluminum or titanium. Anyway… I am waiting for the astrolux competitor.

It’s copper main body with TI batt tube and bezel. The other issue besides baller bling is that the TI conducts heat extremely well and makes the entire light, your hand and the cell get extremely hot extremely fast. My raw alu E07 just on stock top of ramp still reaches 50C in like 2-3 mins. Holding a light that’s batt tube is 40+ degrees after a minute wouldn’t be worth the baller bling imo

TI doesn’t conduct anywhere near as well as aluminum yet alone copper.

You should be cautious not using turbo too often and for too long if you didn’t correct the LEDs MCPCB because it is not sitting properly on the head’s shelf and the heat isn’t evacuated properly to the flashlight’s body. Particularly if yours is the Nichia which heats up very quickly.
