I would like to know the pros & cons of charging 2 new batteries (one deep cycle/one high cranking) with a high output 160A alternator. Do I need a second alternator? Trickle Charger? Where can I get some supplies for this reasonably priced. 99 Expedition 5.4L V8
What do you want to do with the two batteries? One I can assume is for cranking the engine, but what would the other be for? This will make a difference in how you set them up.
