A charger from a range an auto electrician has fitted a hundred times is a charger the installer already knows how to set correctly, and one that gets diagnosed quickly if something is wrong three years later.\u003c\/p\u003e\u003cp\u003eThe DC to DC charging here does the job every dual battery setup needs. It takes whatever the alternator is putting out, which on a modern vehicle with a smart alternator is often less than a deep cycle battery needs, and turns it into a proper multi-stage charge at the voltage and profile the auxiliary bank actually wants.\u003c\/p\u003e\u003cp\u003eMulti-stage is the part that matters. Bulk fills the battery fast, absorption tops it off carefully, float holds it there. A charger that pushes current until the voltage looks right does none of that, and a battery on one of those never quite fills and never lasts as long as it should.\u003c\/p\u003e\u003cp\u003eSize the charger to the alternator first, because one rated above what the vehicle can supply will pull the starting battery down while it works. Then size it to the bank.\u003c\/p\u003e","products":[{"product_id":"projecta-45a-3-stage-dcdc-charger","title":"Projecta 45A 3-Stage DCDC Charger","description":"\u003cp class=\"p1\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eThe Projecta 45A DC-DC Charger is the ideal heart for a demanding dual battery system.
