Question on Dual Batterys
I own a conversion van and thinking a dual battery system may be nice. I think I understand what I need but wanted to clarify something.
I want to install a second battery that will power a inverter that will power a lcd tv, dvd player, charge a netbook or ipod, cell phone and such. The question I have is not really related to using the items when the van is off but when it is running.
Is there a issue to have these items running from the inverter connected to the 2nd battery as the van is driving down the highway. I am unclear on if there is a separation of where the power is coming from if the car is not turned off. And if that load will just get transferred to the alt and burn it up.
