    Default Dual Battery System for Range Rover Classic

    hi

    i have a 1980 Range rover classic,
    i have a winch that i would like to install.
    there is an seperate earth wire already installed in the engine bay.
    apparently all i have to do is connect a battery up to this earth wire and then run
    a cable from the positive of the spare battery to the positive of the main battery,


    any suggestions?

    I dont really know much about this. I would get a NL dual battery system from Echo4x4 in PE. Cant recall the price but extremely simple to install and very cheap compared to the others.

    Its also far safer than the system you have in the above.

    If it's for the winch, I wouldn't bother......I ran my cruiser with a single battery and the KEW winch, and never had any issues. The dual battery system is useful if you have a fridge and there car stands with the fridge running. In that case, just connecting the poles won't help because you'll kill both batteries. Also not sure if your altenator can charge both at the same time.

    Remember the following,
    1. Two batts connected in parrellel will run each other flat in a month or
    so, therefore any time spent without charging will take power out of
    each batt, the longer the time the more the loss!
    2. Standard alternators can not handle charging both batts at same time
    especially just after starting engine. They will look as if they are
    managing but you WILL blow it in the long run.
    3. Ideal second batts are deap cycle type, NOT suited to start an
    engine.
    4. How often do you use a winch If you do not draw power out the
    batt then you do NOT whant to keep charging it. Overcharging
    kills a batt!
    5. At the end of the day do it properly, either yourself as I did, but then
    you need to know something about what your doing, otherwise let
    people like LA sports or Cris Ingram R&D Offroad do it , they are not
    just a prity face. ha ha!

    Well thats just my opinion anyway !

    I don't use the winch often.
    so it does not discharge the battery.
    i also do not use the winch without the engine running.

    It has to do with the plate thickness and differing discharge rates, the LROC club KZN has a few items on the subject. You would like to know I fitted 2 deep cycle batteries, with 1 relay and 1 switch. yes it relies on my memory, but it works. I also upgraded my alternator to a 70 A one. 2 years later no problems yet.
