Quad Pro 4 Bank PS4 Marine Battery Charger

12/24/36/48 Volt 15 amp 4 bank waterproof marine charger.

The Dual Pro 4 Bank PS4 marine battery charger is a 4 bank, 15 amp 12 volt per bank, temperature compensation charger. The Pro series are heavy duty, microprocessor controlled, waterproof, and fully potted vibration proof battery chargers. They feature powder coated aluminum bases suitable for salt water environments. They can be ordered as portable chargers, with alligator clips, and with a GEL charge profile. These independent output battery chargers have a separate positive and negative terminal for each battery bank, and a separate microprocessor for each which controls the charging profile. With this design, they can be used on batteries which differ in state of charge, age, size, or type (sealed, flooded). This works well in applications with a starting battery and a trolling setup. It also is suitable for series strings of 12 volt batteries for 48 volts. Once each battery has its individual positive and negative terminals connected, the microprocessor for each output does not care if the batteries are in series or parallel. This is useful in 48 volt applications where one of the 12 volt batteries in the string supplies some 12 volt loads and the other batteries do not. The batteries in this situation end up with an imbalance condition. A straight single output 48 volt charger used for this situation would not properly charge the batteries and deal with the imbalance.

The PS4 four output 15 amp per bank battery charger is appropriate for 12 to 48 volt applications where wet or hazardous environments exist. They have provisions for mounting (permanent installation), and water, vibration, and temperature are not a problem. The Pro series 15 amp marine battery charger is a preferred charger by tournament fishermen, as the 15 amp rate provides a reasonably quick recharge in an afternoon or evening, particularly if run by a generator. The Pro4 is a well built charger, like all the Dual Pro marine battery chargers, and can be mounted onboard with the mounting flange for dependable service. They are built in the USA (Tennessee), which is uncommon these days for electronic items.
