Battery

Is installing two batteries worth it. Or would i have to buy a high end alternator to go with it? So i don't burn my alternator out.

i have 1 custom alt for my explorer. Spent about close to 300. it puts out about 130 at idle and 200 amps at around 2300rpm
i have one yellow top under the hood and one under the back seat. im not running any fuses between the lines.
Before u get another battery or alt, try the big three.
