you might not need another battery but it is always nice to have extra one i think.
like i said with my stock battery my voltage stays at 13.9 with my 250A Mechman alty.
But I still upgraded to a yellowtop and I am looking to get another yellowtop to put in the rear some day soon. If you can, you should go for Kinetik battery.
Also, I am not running any 4ch or 2 ch amp so I am sure once I have that in my system, my voltage prolly will be lower but still sufficent.
