    New project idea from some batteries bought from Battery Hookup

    Here is a project that I put together from a battery pack and switching power supply and belt pouch holder for the battery pack

    This battery pack was made for the helmet cooling fan or vest cooling
    This was an item that was available from them but it is already sold out

    But I have repurposed it to power a flashlight with 4 power levels the controller board is very interesting that it deliverers four power levels 3 , 5 , 6 , 7.2 volts

    It also lets you know how much charge is on your battery pack

    One note the battery power supply was set to number 4 which is the 3 volt output of the controller

    One other note it does not work correctly with LED light bulbs at all it blinks to much until you get to 6 volts it does not matter if you put a capacitor on the output it just slows down the flashing


    However it is still available in a lower amp hour battery pack and I am not sure if it has the display but I bought a box of them for other projects that I have in mind

    One other note the light bulb is a PR13 ( 6 volt incandescent light bulb )

    Yes I know I can run it at 7.2 volts the light bulb is not going to last very long but if I more light for a short period of time I not going to worry about it if burns out I just going to buy a box of PR13 light bulbs they are not that expensive

          Well the light bulb came in today and I do not really see any difference in brightness of the light bulbs but there might be even though you might not see it
