Dual Pro SS4 Marine Battery Charger For True Gel

12/24/36/48 Volt 10 amp 4 bank waterproof marine charger.

The Dual Pro Sportsman SS4 marine battery charger is relatively new to the Dual Pro line, and is a four bank, temperature compensation, independent output, 10 amp 12 volt per bank battery charger. Be sure you have true gel batteries before ordering this charger. Some batteries are incorrectly referred to as gel, when they are sealed lead acid AGM batteries. The Sportmans Edition chargers are heavy duty, waterproof, and fully potted for vibration resistance. They feature powder coated aluminum bases suitable for salt water environments. They can be built as portable chargers, with alligator clips. The independent output battery chargers have a separate positive and negative connector for each of the four banks, and a separate microprocessor for each bank which controls the charge algorithm. They can be used on batteries of differing state of charge, age, capacity, or type. This is handy in marine applications with a starting battery and a trolling setup, where the trolling batteries, tend to be significantly discharged, and the starting battery only needs topping off and maintenance. It can also be used for series strings of 12 volt batteries for 24 to 48 volts. Each battery gets its own positive and negative connection, and the microprocessor for each bank does not care if they are series or parallel connected. This is useful in 24 volt to 36 volt systems where one of the 12 volt batteries in the string is tapped for 12 volt loads like communications, GPS, radar, etc., and the batteries end up imbalanced. A 24 volt to 48 volt output charger used in an imbalance situation would not properly charge the pack and fix the imbalance.

The Sportsman SS4 four output 10 amp battery charger is suitable for 12 to 48 volt applications where vibration, water, or harsh environments exist. They have provisions for mounting for permanent installation, and are temperature compensating. The SS4 is a well built charger, which can be mounted onboard for years of reliable service. They are built in the USA, and have a 3 year warranty.
