    turn the last 3 batteries 180 degrees
    connect them together as the first 3 and to b -
    daisy chain a link on the bottom of the 6 batteries
    .

    is it from the battery pack?
    if so, its a protection device for the batteries, and not a led driver

    here is another 2s cell protection circuit
    your wiring diagram is correct
    P- and P+ are the supply leads for your LEDs / driver etc

    I'd guess B+/- are the battery contacts, so P must be the output, as Hendo said.

    It's not about speed, it's about lack of control.
