I am interested, but it is going to have to be a really good deal.
+1
interested 
Yup, mod friendly if the head is not glued.
Just as easy as the Supbeam/ThruNite lights we all love.
Just checked specs on X40VN. Only modded from 2,5A to 3,1A to each emitter. Is that max output?
I would be in at the right price. PM incoming!
IIRC he had a v2 at around 4.2a
i believe the batteries are in parallel
I don't think so. Someone please correct if I'm wrong, but it must use the "charge parallel, run in series"-approach, which is used also in the K50 and X60. Quite lot of magic in battery holder.. :)
Count me in I guess. Why stop now.
Yup, I think you’re right, charge parallel, run in series.
V2. 4A to each emitter and batteries in parallel. Source (Thanks JMPaul320)
Stock, the batteries are in series. Charges in parallel like mentioned above.
As far as a good deal goes, does everyone feel they got a good deal on the K50? If so, then this one will probably be a good deal as well. Price is not disclosed for obvious reasons. Anyone that knows what the price on the K50 was, then you should be able to figure out why the price is not disclosed.
Count me in. Obviously depends on price, but I'm interested.
ah yes! thats right… batteries in series for a triple xml2 is a + for this light
vinh is getting better bout tracking the mods, with V2, etc. Way back when, vinh and us all were modding TN31's by adding resistors, and tweaking up amps little bit, being careful, etc. That is until someone, maybe vinh, tried bridging them, then the modded TN31 really hit the pinnacle of it's performance - reigning LED throw leader, until dethroned of course... 
Why? Its not regulated. Seems like linear performance to me. Might as well have been in parallel, which is safer.
True on parallel being safer. The only advantage I can think of is that less stress may be placed on some components due to flowing 4 amps verses 12 amps. Maybe slightly more efficient, but I don't know about that.
Whether that's enough benefit to justify the risk is up each user.
EDIT: Clarified first sentence.
personally I would rather have high voltage and a boost/buck driver than a 4.2v setup for multiple leds (due to higher voltage of xml2 that is)
but thats just my opinion, like you said some might want parallel since its safer
In for one.
This is a 3 cell light, right?
Right.
