Frequently Asked Questions
What is a battery isolator?
A battery isolator is an electrical device that allows a single charging source, such as an alternator or a battery charger, to charge multiple batteries simultaneously without allowing the batteries to discharge into each other. It ensures each battery bank receives its appropriate charge.
How does the Mastervolt Battery Mate 1603 IG work?
It uses advanced MOSFET electronic switching to intelligently direct charging current from a single source to up to three separate battery banks. Unlike diode isolators, it does so with minimal voltage drop, maximizing charge efficiency and speed.
Can I use the Battery Mate with any type of alternator or battery charger?
Yes, the Mastervolt Battery Mate 1603 IG is designed for compatibility with all alternator and battery charger types. It also features an IG contact for specific alternator models that require external voltage sensing or excitation.
What is the voltage loss with the Battery Mate?
The Mastervolt Battery Mate 1603 IG utilizes electronic MOSFET technology which results in negligible voltage loss, significantly less than traditional diode isolators. This ensures your batteries receive a fuller charge from the available charging voltage.
How is the Battery Mate installed?
The unit is designed for easy DIN rail installation, allowing for secure and organized mounting within your vessel's electrical panel. Proper wiring to the input, output battery banks, and optional IG contact is crucial and requires basic electrical understanding.
