Yes that’s what it comes with. Ran a flat top high drain to test
Did you ever find out where the protected battery is set to? I’d be careful with a high drain battery maybe? But glad to know a flattop fits as I’ll most likely toss an MJ1 in mine and toss the Wuben battery in the fridge for another light, another day.
I couldn't resist that $12 deal as I really like the C3 (I did some testing on a previous purchase but gave that unit away).
I measured 4.4A on a 25R, ~1600 lumens plus a proving ground comparison showed me it's between 1500-2000 lumens. The output is consistent on the two units I have/had. As for the overcharging, the indicator light turns green at 4V and I may just have to charge any batteries for it with a separate charger when I can't keep an eye on it.
Out doors the light is very bright and seems to throw further than it should with its wide beam.
Indoors i notice my led is off center. The oddest pattern i’ve seen out of a light so far.
From the outside theres a yellow circle followed by a white square and inside off center of that is the round hotspot.
I’ll probably see what some D-C fix does to it
Not really an indoor light as it's easier to ignore the TIR(?) artifacts outside. DC fix should be a great solution!
Muto and Zappaman - Thanks! Snagged 4 so we shall see. The crappy C8 clones that my kids have abused for years need to be replaced.
Hopefully these fit the bill.
:+1: *got home from TG this evening and just double checked and the battery in my S11c is indeed the better 3000mAh Sofirn. So I am sure it came with that battery (which is a great fit for this light)!
I echo semtex41's thanks. I first saw the S11 on Sofirn's website and could only order the XP-L version. Little did I know it was on Amazon. I ordered 2 for the kids as well! Made my Black Friday more interesting :)
Glad some people got hold of some of these S11c lights this week. For the extra few bucks you are getting a decent 18650, USB C cord, and lanyard in a nicely made light WITH a magnetic tail also- FROM Amazon! -not bad at all guys and gals 
I WISH Sofirn would put the better emitter into the S11b (with it’s ramping mode). I’d love a nicer 5k(ish) tint in a little ramping light like this. But the 6.5k XP-L is pretty blue (in the current S11b) and it’s not a light I’d use in a heavy rain storm (or much outdoors) and really… the S11c’s current IU and super emitter really is perfect for my bedside (and any indoor) use. Barry at Sofirn made a good call there, and I’ll buy a few more when they come back into stock (at Sofirn).

I’m intimidated by the shape of that probe. Looking at a colonoscopy later this month. 
Might be useful for after, just to be safe … 
scheduled my colonoscopy today….for February.

Too much information, LOL! :)
I like customer question #2…“is this a gluten free product?” “yes”
Wuben E05 is $17.70 on Amazon right now. As low as I have ever seen it.
Had to list that deal didn’t you!
Killer light with battery and strong magnet. Great regulation as well.
Made me buy my third of these.
Put a Luxeon V2 3000k in one and it is bliss.
Next one will get a 4000K
The page said I’ll get another $.98 back in Amazon rewards for using the card so that helps on some of the sales tax anyway.
Thanks for the heads Up!!
Later
