2 Bank

Most boaters when they look for an on-board charger are going to purchase a 2 bank marine battery charger from one of the major players in the market such as Dual Pro, Marineco or Genius. We are somewhat partial towards Pro Charging Systems (the makers of the Dual Pro brand utilizing Delta Volt technology) not only because they are made right here in the USA, but because they are so reliable and intuitive. We have not seen a charge profile that advanced before. The Delta Volt technology literally add years of life to your batteries.

All of the two bank marine battery chargers listed below have an IP68 rating. This is the highest waterproof battery charger rating and means they are hermetically sealed and can be fully submersed to depths greater than 1 meter without harmful effect. We offer a range of amperage output levels from smaller 4A maintainers to larger professional grade 15A juggernauts like the PS2.

Maintainer vs. Charger

Most quality chargers on the market today are considered to be smart chargers or microprocessor controlled chargers. By default this makes them both a maintainer and a charger. You can leave them connected to your batteries indefinitely without causing harm. There really is no need to search for a 2 bank battery maintainer for your boat anymore if you have already purchased or plan on purchasing a good primary charger. The main charger will do both jobs, simplifying your life.

Best OnBoard Battery Charger

There are several factors to consider when choosing the best of something. We mentioned earlier which brand we feel provides the best overall benefit, but sometimes it comes down to price, size or another variable unique to your situation.

The Noco Genius chargers are attractively priced and one of the most energy efficient. They have two output ranges at 4A and 10A with the GENM2 and GEN2.

The Dual Pro has four 2 bank chargers ranging in output from 6 amps to 15 amps. The CRS2 allows you to charge on the go. It pulls power from your starter batteries while you travel from fishing hole to fishing hole helping to re-charge your trolling batteries so you can stay out on the water longer. we really love the charge profile and dependability of this brand.

One person could say Noco is the best because price trumps all. Another could say Pro Charging Systems is better because they last forever. We suppose "best" is in the eye of the beholder.
