- Product Description
- The Mastervolt 83304002 Charge Mate Battery Isolator is engineered to provide controlled and efficient charging across dual battery systems. Unlike traditional mechanical relays, this unit uses advanced electronic control to limit current flow to the secondary battery, ensuring the primary battery is always charged first.
- During operation, the system automatically connects both batteries when a charging source is active and isolates them when not, preventing unwanted discharge. The integrated reverse current protection ensures that power cannot flow back from the auxiliary battery, preserving stored energy.
- This isolator is especially useful in marine applications, such as managing service and bow thruster batteries, as well as in RVs and utility vehicles where reliable dual battery performance is essential.
- Important Notice
- This electrical component is non-returnable. Please confirm compatibility with your system before purchasing.
