I was talking with a mate yesterday and the subject of using a car battery with a charger across it as a cheap 12volt supply with high current capability. As opposed to using my 12v 35amp supply.. Note load is not constant, just occasional peaks.
So.. If I take my 12v 6amp charger.. And remove the 12v battery it is across... Why can't I just use that as a solid 12v, 6amp supply..?
I'm guessing it is because the voltage will be all over the place, seeing the load as a wavering battery ... But, practically speaking, what is the 'problem' with this idea..? I've just never actually looked at this in detail.
