Shad0w,
I took another look at your specs from page,1 of this thread, you say this unit will run on most likely an 18650 IMR, (AW,WISE CHOICE) with that being said since 2 x 123 batts will fit the same slot will this unit be capable of higher voltages ? It would be really cool if it was since I also like 6v, but I understand if not because of the risk of stacking batts that modders must take into serious consideration these days, I just had to ask because it would then be able to run HV Atty's & dripping on those is also quite nice.
