Not all boat engine alternators have been optimised for efficient battery charging, however Mastervolt aims to change this with its new Alpha Pro III regulator.

The regulator is one of a raft of products from the company, aimed at making battery charging more efficient.

The temperature controlled regulator is compatible with any alternator or battery type and designed to enhance the efficiency of any type of marine alternator.

It provides a three-step charging process and will monitor engine load to help reduce engine noise and wear and tear on the alternator’s components.

If required it can communicate with the rest of the electrical system via the MasterBus data cable.

Using MasterBus, the regulator communicates RPM, alternator status and charge status to the rest of the electrical system, all of which can be automated or controlled via an EasyView 5 touch screen.

The regulator works with both 12V and 24V systems.

Electronic relay

The new Charge Mate Pro 90 is an electronic relay that allows two batteries to receive up to 90A of charge current from a single alternator.

It is suitable for all battery types including Lithium Ion cells.

The charger will prioritise the primary battery whilst still charging the secondary. Any return current is automatically blocked, even if the secondary battery is of a higher voltage and 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.

The new 90A model supplements the 40A version already available.

1200 watt-hours

The new MLI-E is a 12/1200, 12V battery offering 1200 watt-hours of energy offering long life and deep-cycle discharge in a compact waterproof case.

The battery uses lithium iron phosphate chemistry, will recharge in less than an hour and can discharge 80% of its capacity up to 5,000 times without damage.

A battery management system is incorporated into the casing to manage each cell independently protecting it from excessive discharge, overcharging and overheating.

The MLI-E also has integrated battery monitoring with details including the state of charge and time remaining.
