As far as I have seen they all have the same big disadvantage: Their minimum input voltage is 2.2/2.5/2.7 volts.

In most cases this minimum input voltage is much too high for our flashlight mods în which we often have a max voltage of only 2.4 volts (2 NiMH's cells).

So these National chips are not made for CPF members.
