Pre-order now ReyLight (TrustFire MINI-02)

ok… my 16340 is charged up (measured 4.18V)… popped it in… turn the light on… low … good… med… good… high… a brief flash, then it shuts off… while screwed down/engaged….

whats going here? the light can’t handle the 16340 on high??!

help!

just tried the other 16340 i ordered (3.8V)…same thing… high doesn’t work… it just flashes and shuts off… anyone else??

thanks!

mine is fine on high, what 16340 are you using? trustfire flame?

Same TFs offered with this deal…. :frowning:

Clean the contacts and threads and try again?

I did take the light a part to clean and grease the threads while I was waiting for the battery to charge… The only mode that does not work is high…. If it was a contact issue wouldn’t I have issues with the other modes as well?

Thanks!

The protection circuit modules from the battery is too sensitive, below 3.8V it will work.

The TF16340 I´ve got for testing with Mini-02 has worked fine.

OK…thanks! So to clarify, this is an issue with the batteries and not the driver? Would the fix to be remove the protection circuit? Are the batteries bad?

Thanks!

this is an issue with the batteries and not the driver!!! I´ve tested with some batteries.
to remove the protection circuit will solve the problem.
The batteries are good, but the protection circuit is too sensitive, and that is bad!

Thanks for the clarification… so it is most likely i got a ‘bad’ batch of batteries with overly-sensitive protection boards….?

I’m not sure if I’m prepared to deal with non-protected batteries as I am still a newb when it comes to li-ions… crap… another suggestions for new batteries?

thanks again!

I got mine yesterday. It looks fine, no visible flaws and I grabbed the 2xTF’s with it, both read within 3.86-.87v. NW seems to be a good tint, noticeable next to my 60w warm cree bulb and U2 XML.

It does not want to switch modes if I do it slowly however when an more abrupt, rapid moment is used it is not generally an issue. High pwm, though slightly noticeable. I still have to charge them though, so I’ll report back if that changes the switching function.

it's the battery problem. I asked TF to change the protect PCB.

some orders to US by ePacket is fast,others are on the way.

Is the driver software redesigned or the same crappy bugs in it?

confirmed on my end… battery works only at 3.8V, or less… :~

thanks to fleibaka for the suggestion/diagnosis

This is a real good question. I sure hope someone cough Rey cough took the time to have Trustfire clean up their code and remove that preflash when going into low. I really hate that in my original BLF Mini.

still there… :(, but intermittent… i am finding the threads a bit rough compared to my other lights… perhaps because its ss? or maybe rear spring is too big (too much pressure)?

Got mine yesterday. Fired right up and looks pretty good. Nice tint, good heat dissipation (toasty!), great size. The threads are a bit rough (you can see the machining issues between the threads) but some Nyogel has it feeling pretty smooth. BUT, I am also having the mode hiccup, at first when the light got hot running the TF “880s” right out of the box (but I found that if I cycled through a few times I could still get to “high”), but with the first TF run down, recharged and hot off the charger, I couldn’t get to “high” mode at all (just a bright flash), so it was a 2-mode light. Once the battery ran down a bit (to about 3.85v) I got all three modes. And when the light is hot and turned off, then on, I only get “low” mode, until it cools down a bit. Doesn’t that last problem sound like a driver problem and not a battery issue? The modes cycle flawlessly with a 3v CR123 but I bought this light for output, and @ 3v it’s not much different that my 1XAA lights.

And one more thing: a 47s-branded CR123 doesn’t fit but a regular Panasonic USA model does (and I thought Panasonic made the 47s 123s…)

Rey: If the problem lies with these batteries can we get them replaced?

givwn the price I paid for the cells, I wont be worrying,I’ll likely just source some others at some point, I intend to build a couple of 16340 lights now anyway and I dont intend to drive them hard.

out of interest, what are people reading on high at 4.1v?

IMR 16340 (Not all that many cycles on it (I think)).

4.06V since I got bored waiting for the charger

40mA low

630mA med

2140mA high

Since that’s about 2.5C on high for an RCR123 I’d seriously consider using IMR cells as anything above 2C is out of my comfort zone for cheap LiCo cells. But it may be that the internal resistance of cheap LiCo cells is enough to limit the current.

Mine is an NW version by the way.

I’ll fully charge the cell and try again at 4.2V. Results in a bit.

I can do the same for my CW Mini-01 if you want.

no thats fine thanks Don, my meter got very very wet and needs calibrating/replacing, its a bit high for my confort on such little cells as well tbh, I’ll probably hunt down some inr’s at some point.

for my builds I was only planning on a max of 1.5a so hopefully the cells will be fine at that.
