    Hi,
    I am going to be connecting two 12 V lead acid (7 A h) batteries to a PCB. The PCB has switches and current sensors that connect to a load. I am looking for the best way to connect the batteries to the PCB (max current draw 5 A). The connection terminals on the batteries are fast-ons (0.187" I believe). I was considering using the molex connectors:

    If you have any additional suggestions, I would greatly appreciate them.

    Personally I would avoid those headers for anything over 1A.

    For those currents from a lead acid battery I'd be looking at these: http://australia.rs-online.com/web/p/products/0403960/?origin=PSF_396152|fp.

    We have used them before for wiring batteries through PCB's. Of course you'd not use the 6 way but they come in 2 or 4 way, my net is just a tad slow at the moment.

    For 5A I would be choosing screw terminals.
