Mastervolt electronic relay

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 by always prioritising the primary battery while still charging the secondary and has built-in safety features.

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.

Distributed by BLA, available through marine stockists nationwide.
