    hello,

    i just purchased 3 cree 1000 lumen led's. I plan on making a 3000 lumen med. sized flashlight.

    I have 6x 3.2v 2600mah li-ion rechargable batteries.
    I made a 3.2v 15.6ah power cell with them.
    I need help with figuring out how to charge the power cell.
    The LED's are 3v .700mah each, I believe

    I saw a tenergy 3.2v intellegent 2a lithium charger
    on a site but it was sold out.
    will this work to safely charge my power cell?

    can i buy a dc charger chip board or make one?
    will a 3.7v safely charge my power cell?

    need help, thank you


    I attached a pic of the first flashlight i made
    1000 lumen
    3.2v 10.4ah
    solar panel 200mah

    on a full charge it would run 11+ hours at 1000 lumen
    i need to charge it also

    Hi Hunterstow, welcome to the forum.

    Can you send me a link to the LED you are using? 1000 lm at 3V and 700ma would be the most efficient LED I have ever heard of.

    Yes that charger will work but it will take somewhere around 8-10 hours to charge completely, assuming that it has a trickle charge system. If you can find a 3.2V lithium charger that outputs 5A that would probably be your best bet

    3.7V WILL NOT be a safe charge for your battery, with certain circuitry (very complicated) it would theoretically be safe to a point, but it would be very difficult to use, not to mention dangerous.
