About this product
The Mastervolt Charge Mate Pro Lithium 90 is a current-limiting electronic charge relay designed to effectively distribute charging power from a single source, such as an alternator or battery charger, between two separate battery banks.

Key Features:
- Charges two battery banks from one source with reverse current protection.
- Features a 90 A charge current limit for the secondary battery, suitable for Lithium-Ion batteries and large automotive alternators up to 180 A.
- Automatic 12/24 V detection with an input voltage range of 9-32 V.
- Designed with MOSFET technology for a low voltage drop of max 0.2 V.
- Equipped with LED status indication and a durable, corrosion-resistant IP65-rated casing with aluminum heat sinks.
- Includes emergency start functionality when connected to an optional bypass switch.
- Suitable for marine and mobile applications.
