ProMariner ProMar1 DS Onboard Marine Battery Charger - 10 Amp 2 Bank to 15 Amp 3 Bank

The ProMariner ProMar1 DS Series is a fully automatic, waterproof onboard battery charger built for boats that need dependable, multi-bank charging without babysitting a shore power cord. Each unit runs a 4-stage digital charging algorithm - Analyzing, Charging, Conditioning, and Auto Maintain - so batteries reach full charge quickly and then hold in a safe storage voltage indefinitely, whether the boat sits at the dock or in a slip all winter. The fully encapsulated IP68 housing is waterproof and shock-proof, letting you mount the charger in bilges, lazarettes, or other tight, damp spaces without an enclosure. Available in two configurations to match different battery bank counts, the ProMar1 DS scales from a compact 2-bank charger for smaller boats up to a 3-bank digital charger for larger battery systems with separate house, start, and accessory banks.

Sizes & Options

Match the charger to your battery bank count first, then confirm total amp draw fits your charging window.
