    Default PCB for 7.4 volt pack.

    okay been having some problems with this. i looked at novas video guide on wiring a PCB it went kinda fast so i wasnt able to pick up much details details. but i got a general idea. i looked here and couldnt really find anything helpfull relating to my question,

    CONFIRMING: i DO know that the PCB has 5 pads on it. two is for the output. the other three is for the batteries. one negative one positive and the other is the positive on the OTHER battery i believe i could be wrong on this. its B- B+ and BM.

    well as long as this is correct then i have only 1 question. the PCB i bought from tim has two wires on a clip attached to it. so theres 5 pads and two wires, what are these two wires?

    thats pretty much it. thanks alot.

    You have a connection on the PCB for:

    Positive from battery pack (B+)
    Negative from battery pack (B-)
    Positive to load (P+)
    Negative to load (P-)
    Common (this bridges between positive and negative on the two cells) (BM)

    DJ, you haven't even mentioned what those 2 wires are connected to. Which pads? I'm not sure how you expect to get help with identifying what they are for, if you don't give that info, with no pic.

    What do you mean by "clip"? Is it a connector?

    I believe they are for hooking up a battery level indicator.. Not sure myself actually.

    If you're using the one Tim sells, then those red/black wires are the main power outputs. You can either direct wire to the pads underneath or you can use the wires with the connector.
