M300 is the charger we recommend for boats with both start and service batteries. Accompanying M300 is the maintenance charger M300starter which solely takes care of the start battery. The 25A-charger can then give maximum charging to the service batteries. The charger has a four metre long secondary cable and a temperature sensor for optimised charging irrespective of temperature, which gives extra flexibility in permanent installations. M300 is a fully automatic 8-step charger that supplies 25A and is ideal for batteries between 40-500Ah.
