built myself a triple..
and using a 14.4v battery i built from 12 AA batteries.. gives about 15 volts when fully charged.. did a run test and it ran perfectly for about an hour and 20 minutes..
then dimmed significantly… and the dim mode switch didnt make any difference to the light output.. checked the battery and it was giving about 13.2 volts… im guessing this is too low for three LED’s ?
it kept running for another hour or so though..
would i be better off running with 2 LED’s with this battery?
or would the nimh batteries smudge supplies keep their voltages high enough to give decent run times with three LED’s?
