SF M4 with Pila 600S ?

Hi Guy's

Does the SF M4 work well with Two pila 600S ?

Thanks.

thats only going to put 7.4V on the bulb, wich normally likes 12V, i think the best idea would be to put 3 300s batterys in the m4 using a one cell extender from lighthound. this should fit just fine if not some small magnets could be put between the cells to fill the small gap. i have wanted to do this mod forever but i cant justify a m4 when i can make a ROP LE for less than $100

i think you could just drop an M3 lamp (MN15/MN16) in there and use 2x600s. Is probably the best way to utilize the 2x600s setup.... runtime would be similar to the rated runtime of those lamps on Primary cells.... Cheaper option would be to use the *new* rechargable cells available from AW over in the dealer corner- he has 1600mah protected 17670s that run up to 4 amps before protection circuit kicks them off... meaning they can drive the high output lamps without a problem, just like the Pila Cells, at less than half the cost. (I have 2 cells and a P91 on the way pronto)
