    Hello, can anyone tell me if there is a maximum distance a leisure battery can be away from the van battery? I want to relocate my leisure battery from the front cab to the 'garage' or rear of the van?

    A speedy reply would be greatly appreciated.

    Thank you!
    Steve

    I think its more about the cabel you use.

    My motorhome is built with the battery in the garage.

    Bu i am sure someone will give you the answer you need witin an hour or two..

    theres no limit to how far but its the cable size thats important youll loose voltage due to the resistance in the wire search the web for cable sizing calculators front to back of a van is going to need thick cable like battery leads
    you only need to take the positive wire to the new position and form a new earth point to the chassis /bodywork close to the new battery position again with suitable sized cable
    a fully dischared leisure battery can pull a lot of amps initially so cable must be capable of carrying the full alternator outpu tas a minimum
    i would also fuse the run at both ends with maxi fuses
    heavy cables need heavy duty crimping to fix terminals or solder them on

    Good advise!

    Its a shame the majority of manufacturers ignore basic electrical principles! I wired a Sterling charger to a friends van recently. The leisure battery was in the garage of a 7.5 m van. The standard cable was just 2.5mm!!!!! The voltage drop was horrendous! Poor battery! It never stood a chance of getting recharged!:Angry:

    Thanks for all the replies everyone. The battery is now relocated in the rear of the van, investor in tow!
