I would have thought those would be fine, its not really a mega high asking light from the cells as far as i know. I prefer INR flavour, shorter so easier fit/removal and better performing. Now if you can tell by eye is another thing with this light, but once the voltage drops and under load, the INR cells will not sag like the 3400's. I use samsung 30Q for a few of my lights, this and the k60vn to name 2! These are rated at 15a continuous and 3000mah of fuel. Another option would be the sanyo/LG 10a 3500mah if a little more run time is important.
My most popular are 30q/25r/vtc5 cells, cant go wrong with any of these
Both mine
Get fed
More than happy with the performance, but i dont drain them to the last mah...........
