Mastervolt Charge Mate Pro 90 Electronic Battery Charge Relay

The Mastervolt Charge Mate Pro 90 is a current-limited electronic charge relay designed to distribute charging current between two battery banks, such as a starter and a service battery. This unit ensures prioritized charging for the primary battery while protecting the onboard network from power dips. Its electronic design effectively manages current and prevents return current, even when the secondary battery voltage exceeds that of the primary.

• Charges two battery banks from a single alternator or charger source.
• Electronic MOSFET-based design offers minimal voltage drop.
• Automatically detects and supports 12 V or 24 V systems.
• Compatible with all battery types, including Lithium-Ion.
• Output current is limited to 90 A.
• Corrosion-resistant casing with IP65-rated electronics and aluminum heat sinks.
• Includes LED status monitoring and remote switch capabilities.
• Suitable for marine, mobile, and automotive applications with alternators up to 180 A.
