The new Charge Mate Pro 90 is an electronic relay that allows a second battery to receive up to 90A of charge current from a single alternator. Suitable for all battery types, it is ideal for recharging Lithium Ion cells and has built-in safety features.
An effective solution for high power demand on board in combination with a need for prioritised or current limited charging.
Safety is a priority
When a boat has two batteries on board, typically an engine start battery and a service battery, the second battery usually requires its own charging solution. A mechanical relay will charge the flattest battery first, and then switch to the other, but this isn't always ideal, as it could leave the engine starter battery discharged.
The new Charge Mate Pro 90 works differently, by always prioritising the primary battery whilst still charging the secondary. A very effective solution for charging two batteries from one source while significantly reducing the risk of a flat battery.
An example would be a bow thruster battery and a service battery connected to the same alternator. The Charge Mate Pro 90 would prioritise the service battery for the bulk of the charge, whilst still feeding current through to the bow thruster battery. Any return current is automatically blocked, even if the secondary battery is of a higher voltage, which helps to keep the bow thruster battery sufficiently charged. The current limiting prevents power dips of the on board electrical network. In the event of a main battery failure, an emergency start facility is available by means of an optional bypass or 'battery bridge' switch.
Built to last
Mastervolt is the official supplier to gruelling yachting events such as the Volvo Ocean Race because the products are built to last, and the Charge Mate Pro 90 is no exception. Designed for the harsh marine environment, the relay is suitable for all types of battery chemistry and alternators, and the electronics are rated to the demanding IP65 standard.
The relay is housed in a corrosion-resistant housing flanked by two heat sinks, and its operation can be monitored via built-in LED indicators. The unit includes automatic battery detection, so it can work seamlessly with either 12 V or 24 V systems.
The Charge Mate Pro 90 adds to the existing model line-up, and offers a unit that is easy to install and meets the demand for prioritisation or current limitation.
