I’ve got a p60 Mini Maglite that I run a SF XM-L U2 drop in in. The drop in works much better on higher voltages such as li-ion batteries.
I’ve been running it on some Trustfire Flames. But despite them being newish (Dec last year) one has tripped it’s protection circuit and won’t reset. So I’m looking for some IMR alternatives.
Must ship to the UK.
Thanks.
Efest or AW.
To order from Efest, you have to send an email because shop prices are without shipping.
Hi Chicken Drumstick - did you ever order the lMR 14500s?
I’ve just ordered two from bestvaping and waiting for the p&p quote.
I also had 2 newish Trustfire Flames go wierd on me. The first refused to charge above a certain voltage so I removed the protection circuit and wrapper. This solved the problem - I just need to check the voltage every so often to make sure it’s within a sensible range.
The second, as far as I can tell has either corroded or rusted around the vent holes in the positive end. Again I stripped off the wrapper and the circuit. DMM says it’s at 4.13v and it seems to function ok although the discolouration is a concern. I think I’ll retire it to be on the safe side.
There doesn’t seem to be much choice on the 14500 front from the regular sellers. It’s all **Fire which I definitely want to avoid.
Huh?
There are IMRs from AW and Efest. And protected ICRs from Enerpower, Keeppower, Intl-Outdoor, Nitecore..

Well, apart from IMRs from AW and Efest. And protected ICRs from Enerpower, Keeppower, Intl-Outdoor, Nitecore… there isn’t much choice. 
Quite obviously the internet was broken when I was searching…
Is this light built for one cell, or are you running it on a 14500 and a dummy?
Nope not ordered yet. But was compiling a spreadsheet list of batteries to buy this pay day only a matter of hours ago.
I’m running 2x14500’s at present as the drop in performs so much better on higher voltage inputs. But have low confidence in the Trustfire flames I’ve got at present.
I was just checking, because I was running my Mini-Mags with an IMR14500 and a dummy, but switched to an IMR14650 and a smaller sized dummy for longer runtimes.
Hi,
Newbie here, and I don’t know what “IMR” is yet, but I bought some EagleTac 14500s (protected) recently from “ustcover” on Ebay. They were fairly inexpensive (I think), but they’re only 750 mAh. Shipping was pretty fast (for me, in VA). The listing shows as in VA, but the tracking shows it came from NC.

@vas: :D
@ohaya: Simply put: IMRs deliver more current to the LED but have less capacity. So the light will be brighter (sometimes a lot brighter) but only for a short time.
They are manganese-based instead of cobalt like "regular" LiIon (ICR) cells. Also called high power.. high discharge.. or whatever fancy name the manufacturer picks.
Nightcrawl,
I see, thanks.
Still educating myself, so I’m looking at:
http://www.oveready.com/battery-/batteries/aw-imr-14500-rechargeable-battery/prod_216.html
That’s an IMR, but how would you tell, other than they say it is, i.e., they don’t specify a maximum current, just the voltage and capacity?
Thanks again,
Jim
Yes, its an IMR. The shop says so as does the manufacturer. Both are trusted, so no worries. They should be fine for about 5A discharge. Efest might be cheaper and have more capacity.
Google “efest store” they have good prices on many cell sizes, ship worldwide with only a small fixed handling charge but are much slower than the stateside eBay seller of efest cells “rlsales” on eBay.
What is the difference between the IMR and ICR?
My experience and internet reading says that the best 14500 for now it the Nitecore NL147, not so expensive also. I’ve got two myself, they are behaving great.
IMR can provide much higher currents without a problem, but ICR has higher capacities (usually).
For example, IMR 14500 = ~600mAh and 5A max discharge, while ICR 14500 = ~800mAh and 2A max discharge.
So you should choose depending on what is more important to you.
Curious but where did you get an IMR 14650 from? My original plan was to run an AW 14670, but these seemed to become unavailable just as I went to order them. So I opted for 1x14500 and a spacer. But performance was very disappointing, so I switch to 2x14500. The Solarforce drop in certainly seems to regulate much better on higher voltage inputs.
One other thing to note is, on high draw setups, such as well driven XM-L emitters, you might actually get longer sustained output from a lower capacity (mAh) IMR than you would from an ICR.
Efest sells IMR 14650. For IMRs in all sizes except 18650 and 26650, I would use Efest cells. 18650: Samsung or Sanyo. 26650: MNKE.
For regular ICR cells, I tend to stay away from odd sizes and stick to those available from the big manufacturers.
That means no 10180, 10440, 16340, 18350, 17500, 17670, 22650 and 32650 for me.
Why no ICR 14650?
What about Sanyo UR14650? http://launch3telecom.com/pdf/sanyo/ur14650.pdf
Simply because I didnt know it existed. :P
But its a weird size. 14500 replaces AA cells, but 14650? I'd just use 18650 right away.^^
