NOCO® HP Battery Isolators. Eliminates multiple battery drain and prolongs battery life!
Many vehicles have multiple batteries: one dedicated for starting the engine and the other to power accessories. Without a Battery Isolater, a battery with a lower charge will draw power from a battery with a higher charge, until the batteries equalize. This problem is known as multiple battery drain and it could leave you with dead batteries.
This Battery Isolator will prevent current from flowing from one battery to the other, and each battery will act as an independent power source. This ensures that the battery you dedicated for starting never gets drained! A Battery Isolator also allows you to simultaneously charge both independent power sources at the same time.
The amount of current which flows into each battery is then determined by the battery's own state of charge (based on voltage regulator settings). Ideal for recreational vehicles, boats, cars, utility vehicles and trucks! Install Kits also available below!More:
