(1/7) > >>

TUFFTEE:
I have 2 Brand new Heavy Duty Batteries Which i want to Wire in Parrallel so that i get 12volts and both batteries are working together? as well as being able to run the winch when required?

muddymart:
Hi, there is a topic on this somewhere,but i'm having trouble finding it,use one battery as usual,and use a split charge relay to charge the second one up, use the second one to operate winch/cb's/lights etc.. i think thats the best way round it

here it is.

If both batteries are identical in every way there should be no need for a split charge system.  If you are just connecting the batteries in parrallel both will charge together and drain together.  I would act just like a bigger battery with more cells in it.

You only really need a split charge system if you are having 2 different batteries like a standard and a leisure one.  If you connect 2 different ones in parallel the larger powered one will try and charge the smaller one and will succeed in making it overcharge and over heat.
