Can this handle 14500?

    with any luck, it will still operate on 14500's, even if it no longer works on AA's.

    of course, having said that, it would be really nice if we didn't always have to guess and experiment. i know, wishful thinking, but not really too much to ask for.

    I agree DX should have better and more accurate specifications. But this time I see no need to blame the seller, because this one is clearly not specified for li-ions. Of course anyone can try to "overclock" it, but what happens then should not be the sellers headache.

    Anyway, I shortly tried how much current it draws from the battery with different input voltages. Current it draw was always almost exactly 2 amps when supply voltage was between 1.4 - 3 volts. I didn't want to burn it so I stopped to 3 V (equals to 6 watts input power). With 70% or more efficiency the driver already overdrives the emitter then. So it always takes more power when battery voltage raises. According this I'd say it is not suitable for li-ions (at least not for a long term use).
