Mastervolt Charge Mate Pro A secondary battery on board requires a dedicated charging solution. The Charge Mate Pro makes it possible to distribute the charger or alternator current effectively between two battery banks such as a starter and a service battery. The Charge Mate Pro connects both batteries during charging and keeps them isolated when discharging. This significantly reduces the risk of a flat starter battery for example. Features - Electronic charge coupling with very low voltage drop. - Makes effective dual charging possible. - Suitable for all battery types, including Lithium Ion. - Charge current secondary battery limited to 40A. - High system reliability by prioritised charging of the main battery. - Unidirectional which blocks return current under all circumstances. - Prevents power dips of the onboard electrical network. - Suitable for all kinds of chargers and alternators. - Monitoring with LED status indication. - IP65 electronics in a corrosion resistant casing with aluminium heat sinks. -Fast and easy installation.
