ProMariner on-board battery chargers


THE new ProMariner marine battery chargers deliver fast charge times and battery conditioning without the need to haul portable chargers onto your watercraft.

The ProSport Generation 3 On-Board Marine Battery Chargers incorporate “distributed-on-demand charging technology”, which takes 100% of the available charging amps and distributes them to any one or combination of all batteries as needed for faster charging. ProSport is 100% waterproof and shockproof, weighing 40% lighter than older epoxy filled chargers, providing cooler operation and greater reliability. Each ProSport model has digitally selectable charge profiles including a once-a-month storage reconditioning mode for extending battery life.
