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.\u003c\/p\u003e\u003cp\u003eThe Charge Mate Pro offers an additional advantage over mechanical charge relays, by limiting the charge current to the second battery. The primary battery, like a starter battery, is therefore charged with priority. The return current is automatically blocked even when the secondary battery has a higher voltage. An emergency start function is possible by connecting an optional bypass switch to the Charge Master Pro.\u003c\/p\u003e\u003cp\u003eA marine application example is the connection of a bow thruster battery to a service battery. The Charge Mate Pro ensures that the service battery is always charged with priority. The blocking of the return current from the bow thruster battery guarantees that the bow battery remains charged while the current limiting also prevents power dips of the onboard electrical network.\u003c\/p\u003e\u003cp\u003eThe Charge Mate Pro series consist of a 40 Amp and a 90 Amp version, both suitable for charger or alternator applications.\u003c\/p\u003e\u003cp\u003eCharge Mate Pro: for controlled charging from a single source.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eLeisure and professional marine and mobile applications.
