V10R Ti and IMR16340?

Hello,

I'm wondering how an IMR16340 would run in my Sunwayman V10R Ti? I've been reading about using them in the newer XML T6 V10Rs, and I realize that they have better output (with the effect of reduced runtime), but I was wondering if I could have the same effect in my V10R Ti with the XP-G? I thought I remembered someone doing that a while back, but I couldn't find it.

I'd appreciate any info anyone has on this...I have some nice flashlights, but I'm still trying to learn the lingo and specifics of how everything works together! I know the V10R Ti is rated to 4.2V, so I was hoping that I could pop a IMR16340 in and boost my output!

Thanks!

With the XML, the current demands can be near (or even over) the max rating for a protected LiCo, whereas IMRs can handle the current easily. But the XP-G current is easily handled by both LiCo or IMR, so I wouldn't expect any output difference at max. I vaguely remember checking this out -- in fact, I used to run an IMR in my XP-G v10r and subsequently switched to protected LiCo -- and finding no difference, at least by eye. If no one else has verified this soon, I'll re-do this and tell you what I saw

AFAIK the V10R is safe to run on IMR16340, at least my V10R is doing fine with the IMR's

Emu, he wasn't asking if it's safe, he's asking if he would get an output boost vs a LiCo 16340 ... although now that I go back, I see I read too much into it -- I don't know if he wants to compare vs a cr123 primary, or a 16340 Lico

Thanks for the responses so far.

Joe, I'm currently running Surefire CR123 primaries in my V10R Ti. I'm curious if a IMR16340 will provide a boost in output vs a primary CR123. I suppose I'd also be curious if a 3.7V RCR123 would also provide an increase in output.

Ok, I tested my two V10R Ti's side by side with AW16340 / IMR 16340.
I would say there's no noticeable difference in output. :shrug:

Okok, wait a minute , I'll do the test IMR16340 vs. SF CR123.

Definitely more lumens !:devil:
But I think you will have the same result with a RCR 16340.
Hope this helps

My V10R xp-g and V10R AE XM-L T5 both pull about 2A from an IMR and 1.5A from a normal LiCo li-ion. The XM-L is quite a lot brighter than the XP-G :devil:

V10R Ti XP-G R5 on disposable CR123's with 3.0 volts and some 1500 mAH will deliver only 160 lumens, but some 2 hours run time.
On AW RCR 16340 Protected 3.7 volts 750 mAH batteries, it will deliver 210 lumens [thanks to the higher voltage], but much shorter run time; the actual run time has not been independently tested by a reliable source like Selfbuilt.
On AW IMR 16340 3.7 volts 550 mAH non-protected, the V10R Ti R5 will deliver the same 210 lumens [thanks to the same 3.7 volts], but @ 550 mAH, it has the shortest run time of the lot, and you must ensure that you don't run it any further after it flashes or cuts off automatically to prevent overdischarging, and to recharge it immediately if possible, to prevent permanent damage to the IMR chemistry battery, which cannot have a protection circuit.

While the old XP-G R5 emitters run to a maximum of 1.5 amps, the new XM-L's can run to a maximum of 3 amps.
So if the XM-L is driven at roughly 1.5 amps or more [to produce roughly 500 lumens], then in 16340 size, it will need IMR chemistry which has less internal resistance, hence a higher discharge rate, hence can deliver up to 4 amps, where an RCR chemistry 16340 can only deliver up to 1.5 amps.
Thus 16340 powered XM-L seem to be limited to 500 odd lumens, because they are mainly designed to draw current from an RCR chemistry, and not an IMR chemistry cell which is a lot trickier to use.
A 16340 on IMR can deliver 1000 emitter lumens, but more skill is required to use, and look at the run time from 550 mAH...

Take note that the bigger RCR 18650 has lower internal resistance, and a faster discharge rate, than the smaller RCR 16340.
The 18650 AW 2900 mAH can deliver some 5.8 amps, or 3100 mAH @ 6.2 amps etc.
Thus bigger XM-L flashlights can easily use RCR 18650's, and don't have to use IMR chemistry, unless they are drawing absolutely huge amperages...

If my readings are correct you should get quite a bit more than 210 lumen with a xp-g and IMRs since Selfbuilt estimated 260 lumen (V10A on an AW 14500) on a LiCo and with mine it pulls 33% more power from an IMR than an AW li-ion.

Has emu124 tested his two (2) Sunwayman V10R Ti XP-G R5's side by side for brightness, on RCR 16340's versus IMR 16340's yet?
And let us know the results???

My friend's RRT-0 XM-L was much the same on both types of batteries, although we couldn't really tell, because we did not have two (2) of the same flashlights running side by side...

I have the Sunwayman V10R Ti R5. Please see below for some if my Lux readings.

AW 16340 protected cell 5,880 Lux
AW 16340 IMR cell 6,170 Lux

I hope this helps.
