i've rigged a step up board to a constant current charger curcuit, and wired to a 7.2v maglight krypton.
(the charger curcuit sets volts and amps seperatly).
24 volts open curcuit and the upped the amps untill the bulb switched on.(as in it was off untill then).
@ 790mah the bulb pinged on nicely.(gets brighter if the amps or volts are upped).
accross the bulb is 7 volts.
accross the output of the charger part of the curcuit measures 7v..
the question, why?
surely there should have been 17 volts accross the bulb and not 7v?
and why didnt it switch on before 790mah?
