    Upto now I've been charging lithium cells with the end of charge cut off module from a Vapourlites e-cig, but recently I won a scrap laptop battery pack and the cells need more current to charge in a reasonable time - the Vapourlites module can't be driven any harder.

    Having googled for a couple of hours, I think my searching mobo must be broken.

    Anyone know where to look for discrete component lithium charge control circuits?

    AFAIK - the Vapourlites capsule simply disconnects the battery from the USB charging adapter.
