how do u ho0k 2 batterys up in a car can u just run ur power wire from the stock battery upfront an run a thick gauge wire 2 the trunk an put it 2 the + an just ground the - ?
you would need a battery isolater it charges one battery at a time then would charge the other when the others one done otherwise the alternator would have to charge 2 batteries at once and that might be a tough task for it
goto a car shop and ask the guy that to be sure say i got a ho alternator would i still need a isolator for 2 to 3 batteries see what he says i would think u would still need the isolator but ask to make sure
Same here...I just added a red top Optima in paralell wit my other battery and havent had any problems. Make sure you get a nice size wire to do all this, and make sure you have a good ground.
