    Dual Battery SystemsAdvantages of a Dual Battery System

  • You can have the traditional dual battery system, which is a deep cycle battery which is isolated from the starting battery.
    This allows you run camping appliances without the risk of flattening your starting battery.

    Or you can run two cranking batteries in parrelel to double the amps available to your starter motor or winch, making either work a lot better when under load.

  • You get to start your vehicle engine after camping all weekend with the Fridge running & the radio going;
  • You can still start the engine again after winching your vehicle up and over that last dirty great rock step or thru the river where the engine stalled;
  • You can camp for 24 hours without having to run the engine for at least an hour to recharge the battery; and probly a heap more along those lines.
  • If you go off the beaten track, it’s an insurance policy against having a battery fail & finding that it is impossible to get jump start you where you are, and to get a tow truck in.
  • Camping, winching, even just four wheel driving is hard on batteries, and many vehicles simply don’t work too well without some electrical power, so a dual battery system means you can get back to civilisation instead of having to leave the vehicle out there while you walk out!
