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.. :)
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.
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...
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.
