    On my next boat I plan on using my current trolling motor which is a 24 volts MK. So, I know I gotta wire them is series. My question is. How will I be able to run my bilge pump and navigation lights (12v)? I will be able to right?

    Yes, just wire the 12v stuff to one battery as normal.

    Only the trolling motor will be 24v if you connect to both batteries as usual.

    but if they are in series, won't everything coming from the batteries be 24v?

    We do this all the time for hydraulic suspensions in cars.
    The front pump usually goes anywhere from 72 volts to 96 volts, while the back pumps go at 48 volts.
    Then the switch box goes at 24 volts.

    Do you know how many little boxes I'd have to draw and label?    :D

    Still, it's just a continuation of the existing drawing of batteries wired in series.

    1 battery is 12v
    2 batteries is 24v
    3 batteries is 36v
    4 batteries is 48v
    5 is 60v
    6 is 72v
    7 is 84v
    8 12v batteries in series produces 96v

    Man, good thing thats in a car, that'd be a lot of ballast in a small boat.
    But you'd be able to run an air conditioner for awhile... ;D

    Yeah, and we sometimes run 8 batteries at 76 volts putting 2 batteries on reserve. :D
