  • Trojan t105's distance between two batteries (picture included)

    Trojan users would 6 inchs of 2 awg cables be sufficient to connect these two batteries, at points highlighted in picture? i am currently using 2 awg 1feet but there's too much slack , got new vents for my batteries and need a tighter connect so my water misery caps will fit cleaner

    More than enough. Factory Golf Carts use #6 AWG and pull up to 275 amps and run 75 amps continuous. Racing Golf Carts pull 600 amps and use #2 AWG with much longer runs than you are using. My EV uses 1/0 only because I have access to it and the tooling to terminate it.

    No worries.

        i wasn't so much worried about the gauge but rather the length? Would 6 inches be enough to connect those two batteries

            Just seemed like a good thread to ask something I've been wondering about. 95% of the time, in a boat or RV, you won't have much of a choice how tightly your batteries are physically packed together, but in a shed, or garage, or cabin you might get a larger canvas.

            Let's say you have a battery bank and your choice of cabling them up with short 6" cables that means that adjacent batteries touch or longer 12" cables that allow you to space the batteries apart as much as 6". Which set of cables do you grab?

            1. 6". The pros of shorter cable connection outweigh any temperature differences between middle and edge/end batteries.
            2. 12". The pros of an air gap to provide more equal temperatures outweigh the extra resistance of an extra 6" of 2 AWG or 1/O.
            3. Other considerations should be at least as, or more, influential.

              the cables should be of large enough gauge, that the extra 3 inches will not make an appreciable difference. 2" between cells is pretty generous, 6" is wildly excessive.
