I like the bottom one best. Keeping the L6 stock with resistor boost. If I want throw, I’ll grab one of my dedicated throwers.
Thanks again!
Yeah, it’s hard to avoid the donut shape with the SMO. Running the xhp50.2 does help, but it’s not as bright and has a very yellow corona. The xhp70.2 will be nice and bright with minimal donut shape, but still the yellow corona. I’m guessing. We’ll have the wait and see.

What?
Did you post this in the correct thread?
Okay, I am back. I received my new Uni-T UT210E so my current measurements will be in line with others here. I used a 6” length of 10 gauge wire on the tail cap. I measured both the Liitokala and KeepPower 5200 protected cells. Emitter was the xhp70, no 50.2 this time. I only tested each for maybe 5 seconds so I could do a lot of tests without having to fully recharge the batteries each time. The hundredths place was rounded to the nearest 0 or 5. Springs are bypassed with mesh copper braid used for desoldering.
First up is the stock FX-30 driver with the 2 R082 resistors, no mods.
Liitokala
Turbo/high = 4.60 amps
Med = 2.55 amps
Low = 0.55 amps
KeepPower
Turbo/high = 5.10 amps
Med = 1.90 amps
Low = 0.45 amps
Kind of strange, I double checked it. Does anyone have a answer as to why the Liitokala were so low on turbo compared to the KP, yet the lower levels seemed normal? This is the first time I paired my Liitokala’s with an unmodded driver so the results are surprising.
Next is with an R100 resister stacked on top of the 2 R082’s.
Liitokala
Turbo/high = 7.00 amps
Med = 2.60 amps
Low = 0.55 amps
KeepPower
Turbo/high = 5.70 amps
Med = 1.90 amps
Low = 0.45 amps
Next is with no added resister, but added a wire across.
Liitokala
Turbo/high = 7.70 amps
Med = 2.70 amps
Low = 0.55 amps
KeepPower
Turbo/high = 6.10 amps
Med = 1.95 amps
Low = 0.45 amps
So 7.7 amp is the most I can get from this driver with the xhp70. My borrowed meter read 8.1, but all it’s readings were a little bit higher compared to the Uni-T meter. Also, all my readings on the next lower power level showed the Liitokala as 0.70 amp higher than the KP.
I’m going to stick with the R100 mod for the time being. Once I get my lux meter back I’ll do some comparisons between batteries to see how much brighter just a battery swap can be. I’ve also got some R082 and R120 resistors I can try, but I doubt there will be much difference over the R100. Plus it’s a pain soldering those things. :confounded: Maybe a smaller soldering tip would help.
This is just a heads up gang. A few moments ago I discovered that the most recent batch of Keeppower protected 26650s is much larger in diameter than the last shipment, and therefore no longer fit the L6 body.
I was able to get them to fit ok in the body tube of my original ( one that was made before the logo was added) because it had an ID about 0.006 larger. I’m not faulting Convoy for this, just saying they did fit my older one.
So is the battery larger, or the L6 smaller?
Recently I bought a silver L6, and the Keeppower 5200 batteries that I have in my slightly older black L6 do not fit. I got frustrated, and just put in some 18650’s. I was actually about to finally order a couple more KP 26650’s, but now I’m worried about them fitting. Anyone else have this problem?
Ohhh boy. I just placed my first order for an L6 yesterday. And ordered a couple Keeppowers (from Banggood) at the same time. It probably doesn’t matter, but what vendor were your batteries from?
Curious about this as well:
Got my L6 today and I just can’t believe how bright it is. And how big it is. It looks smaller on pictures 
Best light I had before was C8 and this is so much brighter I have no words for it.
Mostly its the batteries that got larger. Last batch was around the 26.4mm size and this one maxes at almost 27mm.
It might make a difference. If banggood still has stock that was purchased before about January ish they may be just fine. I had to wait about 2+ months to get this stock. What’s really lame is I ordered a whole bunch extra so I could stop running out. Being out of the KP cells was holding up shipments of the L6…. Such is life I guess. :student:
I have calipers now, so I’ll have to take some measurements. I seem to be having the opposite problem, in that my older KP’s don’t fit my newer L6. I guess I won’t know for sure until I take measurements. By the way, I ordered my KP cells 11/29/16 from illumn.com, my black L6 from Gearbest on 11/11/16, and my silver L6 from Gearbest on 1/26/17
Yeah, I think I’ll just wait until Simon someday redesigns the L6’s dimensions so it fits most 26650 cells. It’s hard enough to get any li-ions at all because of the “hazardous air shipping” monkey talk.
That’s a pretty big increase in the cell diameter. Makes me wonder if they’re double wrapping them. EVVA was doing that for a while on protected button tops. It was wrapped once to add the button top and then wrapped again when they added the protection circuit. That was making their cells too fat for many of my convoy lights. In that case Richard contacted EVVA about it and they started single wrapping them for him.
Maybe I can work out something similar here. Matt, did you buy your cells from Banggood using the link they setup for the L6? I can have the Banggood rep talk to the KeepPower rep to resolve this going forward.
Also please let me know if you’re seeing variations in the ID of the Convoy tube. I’m not worried too much about a difference of 0.006 in the ID but if we’re seeing problems with cell fitment caused by variance in Convoy manufacturing I’d be all over that. Shoot me a PM if you want to discuss any of this in more detail.
Oh wow. I just received 4 protected KP from Illumn that measure 26.72mm - 26.75mm. My previous (shorter length KP) measures 26.25mm. They all fit my 3 lights, but just barely. Requires a ramrod to shove them in on my newer Clear L6’s (from Banggood this month). But have more room in a older black L6 (1st with logo, I believe)(which I bought from Matt many months ago). Lengths are still ok, 69.57mm (new) vs 69.39mm old.
Edit
PS. Measured including the metal strip running up the side.
PSS. Latests non protected KP, also from Illum, measure 26.25mm including label.
PSSS. The fit in the new Clear L6 is tighter at the tailcap end than at the headstock end.
What are your battery tubes measuring?
Hmm… that makes me wonder if they are indeed double wrapped now. Any way to compare the wrapping on your old and new ones?
My tubes are
Clear = 26.79mm & 26.83mm (Opposite ends)
Older black = 26.89mm
As far as rewrap, not that I can tell, looking under top or bottom fold over. But if a stock wrapped battery has a new tail & positive button added, then re wrapped, I wouldn’t neccesaily see that.
My cells are not from banggood. I messaged Keeppower about it, but if you can talk to any other dealers that are having this issue so they will speak with keeppower that would be awesome. The more people they hear from (hopefully in a nice way) the better our chances of having this resolved is.
The variations in the body tube are all within reason. I mainly posted this here because Convoy users are the ones who will be most effected by this. I would not object if Simon wanted to add a few thousandths of an inch to the ID moving forward, or some length, but don’t see the light as being the problem.
My first one measures about 27.12mm The newer about 26.87mm Slight variations of those numbers can be had if the calipers are turned.
Hmmm 26.87mm (1.058”)
