I'm all in favour of that, let's just keep it friendly :wink:

I'm going to disagree there.... IMHO, split charge systems have no place on a competition vehicle... just more money and complication you don't need.
Bulli:
Tim that echos what i was saying earlier.
Split charge is great in a overland / expedition vehicle when a dead battery means you are stuck miles from help.
They just help to kill the battery if you use one to isolate when winching. As they stop the alternator charging the battery attached to the winch. This then overloads the batt and as the voltage drops the amp draw increases...qed dead batt real quick.
2 batts linked together are better as the voltage drop is slower, helping to reduce the load.

--- Quote from: "Bulli" ---mudlark, your answer above shows you dont really grasp electrical winch thing at all..All electrical winches can and will draw huge amps (450+) alternators only throw out max 140.

I wrote without checking :oops: :oops: :oops: :oops: :oops: :oops: :oops: :oops: :oops: :oops: :oops: :oops: guess I had the no load amps stuck in my brain.
So this basically means that a deep cycle should be used for the winch and not rely on a single battery.
Your split charging theory is interesting as well, surely the alternator should be programed to charge the discharging battery or in the case of petrols the major discharging battery?
Does this not happen with a charge splitter?
Bulli:
no split chargers are designed to protect the starter battery, which is not the one generally used for the winch. Thats why they are used for exped trucks. Thye can run fridges lights etc without the risk of not starting the following morning.
Most systems dont like to be connected to anything drawing that level of amps...it tends to fry them!!
