I like it, workng on a review.
Made the beamshots yesterday.
Cool thing, at 800 meter is the castle.
yesterday night I looked at the tower after they shut down the show lights.
I looked through a monocular in the direction of the towers, since I could not see it in the dark.
S70 on Turbo and bam there they were! Very cool.
When the weather permits will test the S50 tonight, to see if it can do the same.
Mine’s been working great. Quite a value for the cost.
Running King Kong 26650 4000mAh ICR26650 button tops (67.7 mm) - good fit
and used Sanyo/Panasonic NCR18650GA 3500mAh (69.0 mm) - very tight
Hmmmm…
So for this S70.
King Kong the best bet?
https://www.fasttech.com/products/0/10003591/1263001-king-kong-icr26650-37v-4000mah-li-ion-rechargeable
But it show 68.4mm?
Edited: Vs Vappower 4200
Or Vappower 5200mAh?
Which is more preferable?
Cos i getting “x” numbers of batteries.
For J18/X100 as well, on top of S70.
Thanks.
I was considering King Kongs but wonder if there is enough advantage over a 3400 mah 18650 cell to make it worthwhile getting them ?
On paper the capacity gain is only roughly about 18-20% whereas if you got 52000 mah 26650 cells the capacity gain is roughly 50%.
Obviously I know that the above is dependant on the cells actually having the claimed capacity in the first place.
Your biggest advantage is much less voltage sag. Factory 5.5 amps or modded to even higher and 18650’s get warm and lose some capacity where 26650’s are just sailing through. Looking at the test done by HKJ the 3400 mah Panasonics have 3040 at 5 amps. The 5200 mah Keeppower have 5080 at 5 amps, with voltage staying much higher the whole way. In Panasonics favor I don’t fear their unprotected cell. The 26650’s need to have PCB’s.
I wasn”t suggesting not to use 26650”s but to use 26650”s of around 5000-5200 mah in preference to 4000 mah to get longer run times.
Why do 26650”s have to be protected ?
For one thing I don”t think that protected cells will fit the S70.
Since I intend to use the S70 on Turbo much of the time (resetting after 3 mins as needed), I wanted a high-drain 26650 to ensure best performance.
These appeared to be the best balance of performance/capacity that would fit properly:

Do you think that they would out perform an unprotected button top of around 5000-52000 mah that is rated at say at least a constant 10 amp then ?
Is this the same cell as the graphs are for a King Kong http://www.banggood.com/2PCS-INR-26650-E-Protected-4000mAh-3_7V-Li-Lon-Rechargeable-Battery-p-917357.html
Sounds like a 5000-5200mAh at 10A would be fine - I just couldn’t find one short enough to work…
Seems like the same cell but the quoted length (if accurate) is longer (69.5 vs. 67.7). Mine are a tight fit already.
Because the 26650’s are made in China and I don’t trust the quality control in multi cell lights to them. Single cell lights don’t get uneven voltages. The PCB’s add that level of safety.
I have spoken to HKJ & he has recommended Keepower IMR 5200 mah unprotected button top cells at 67.40mm.
Here is his review of the cell Test/Review of Keeppower IMR26650 5200mAh (Black) 2015 | Candle Power Flashlight Forum
I am going to go with his recommendation 
Sounds good - let us know how they work out. I need a some backup 26650s.
PD, I have one I ordered from Amazon for review and I LOVE it! Measured a bunch of lights tonight on the IS and included the S70.
4,545 OTF lumens and 9.22A being pulled at the tail (2*4.61A). No mods performed and running KK 26650 cells. Wonderful light!
That would explain some of the beam shots that I have seen where it would appear that it is more than 3000 lms
It is impressive that is for sure.
Nice to see them understate specs, normally it is the other way around.
The S50 has longer runtimes then Thorfire claims, also very nice.
i think you canot add the Amperes from cells in Series 
4,6A stock is still impressive
I don’t doubt at all that it’s a great light, I am thinking about getting one.
But are these beam shot’s realistic?
Those pics seem to show an accurate representation of the difference between mode levels. But if you want to know if that’s how it will look to your eyes, I don’t know. I don’t have your eyes. 
I second PD here.
Both the S50 and the S70 produce a massive amount of light and shining them through a tunnel of trees like in the pics would certainly give a result similar to what you see there.
I liked Thorfire before I got the S50 and S70 because when looking at the descripton of the VG10 they wrote something like “the tactical ring is renewed, the older one sucked (yes they sed the word suck) so it needed replacing” this is so not marketing speak (I hate those slick marketing talks) and it won me over.
I bought it. The VG10 is very nice and the quality and preformance of the S50 and S70 seem more then they promise us. (longer runtimes, higher lumens) and combining that with 2 year warranty and a compagny that is responding to people (unlike the unanswered emails I send to Sunwayman about a more expensive light or the stories about Olight being not responsive)
I finally received my light in the mail today. Very happy with an as is factory budget light and that rarely happens. Output, 4 mode spacing, size, it’s all as advertised. Current readings and a thorough stripping is not happening anytime soon. The two mod’s I do see are as follows;
1st thing I noticed is that the batteries are tight regardless of length. Springs are thick and well coiled. One modification I like to do on high amps light is stick these in. Gold Plated Beryllium Copper Spring 5mm H x 11mm D Both this and the original spring is 1mm dia. however the replacement is a better material. This should now allow the longest batteries listed to be used. My choice is King Kong 26700 with a magnet. Probably only replace the one under the driver to allow the tail spring to give that battery tight push needed for different lengths.
2nd thing is to look at the driver for a modest current bump.
Output is impressive, but all mods are on hold until my shoulder heals I’m in day 13 of rotator cuff surgery.
