The ProMariner ProSport Generation 3 is an onboard marine battery charger rated at 20 amps with three battery banks. It uses all-digital microprocessor control and comes pre-wired, so installation is straightforward. The case is compact extruded aluminum. Built-in protections include ignition protection, and while the boat sits in storage the charger reconditions the batteries once a month. LED indicators show charging and conditioning modes, and the maker backs it with a two-year warranty.

Our take

Three banks on one 20-amp charger means a single unit can look after three separate batteries. The monthly reconditioning cycle during storage means batteries on a boat that sits idle still get regular attention without anyone visiting.

From our buying guide

NMMA says charging sources must meet the charging profile the battery maker recommends. A charger's presets are its own maker's, not the battery's, so set it from the battery maker's figures.

Check before you buy:

  • It can follow your battery's profile, since not every charger can follow a lithium maker's.
  • Its output suits your bank. ProMariner recommends about 10 percent of the batteries' total amp-hour capacity, with one charger output for each battery.
  • It suits how you'll use it, since ProMariner says its waterproof chargers are for batteries not in use while charging.
