so, i need a very affordable 12v system. im almost donemy vehicle. all i have left is wiring everythingup together. i cannot afford the 150-300$ of a dc-dc converter.
should i buy a 80ah 12v rv battery (50-60$) + i already own an old 12v charger.
use the car battery the car came with, and use a laptop as a small dc converter to help it?
do i even have any other options?( i dont have power windows, and i bought led lights or the car, so i dont need a very powerful 12v system
any advice asap would be wonderful.
thanks
