48 VOLT BATTERY CHARGERS


We carry 48 volt battery chargers in a couple of styles, and models for varying applications. There are multiple output chargers, and straight 48 volt output units of different amp capacities, and connector selections for various golf cart or industrial applications. We currently offer Dual Pro chargers made in Tennessee, with a 3 year warranty.

The Dual Pro Eagle 48 volt battery chargers are industrial grade chargers, with fan cooling and temperature compensation of the output charge, available in 9 amp and 18 amp output. The Eagle series are a heavy duty, microprocessor controlled, thermally protected charger, encased in a powder coated aluminum case. They can be portable or bench top chargers, with a padded handle. They are available with alligator clips, or an Anderson connector of the appropriate size and color. 48 volt systems usually use the blue Anderson SB50 50 amp connector.

The Dual Pro Eagle series combine the reliability of a heavy duty transformer, with a microprocessor controller, for long term performance and proper battery management. With temperature compensation and computer control, a quicker, more efficient charge cycle results in complete battery charge, better battery life, and less water loss in flooded batteries. They are safe for the sealed lead acid batteries as well. Eagle 48 volt chargers, like all Dual Pro battery chargers, turn off completely when the charge is finished, and reactivate the charge sequence if battery voltage drops to the factory preset level. The LED array on the charger case indicates status of the battery.

The Eagle series are made in the US, and feature a 3 year warranty. The Eagle is suitable for moderate to medium use 48 volt systems, including floor scrubbers, golt carts, cargo carts, scissor lifts, personnel carts, and other industrial equipment. Battery capacities from about 36 amp hours and up are appropriate for one or the other model charger, depending on use and desired recharge time.

The Dual Pro Sportsman SE4 marine battery charger is relatively new to the Dual Pro line, and is a four bank, temperature compensating, independent output, 12 volt at 10 amp per bank battery charger. This charger can be used as a 12 volt charger at 40 amps, or in a 24, 36 or 48 volt system using a combination of 12 volt batteries. The Sportman Edition chargers are heavy duty, waterproof, and fully potted for vibration resistance. They can be built as portable chargers, with a handle and 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 48 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 straight 24 volt to 48 volt charger used in an imbalance situation would not properly charge the pack and fix the imbalance.

The Sportsman SE4 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 SE4 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. Each output must be connected to a battery (can be the same battery) for the charger to operate.

Battery systems using 48 volts are found in industrial systems, golf carts, floor scrubbers, scissor lifts, etc. They usually involve a four 12 volt batteries hooked in series, or eight 6 volt batteries in series. Battery packs in multiple battery applications are recommendended to be of the same age and capacity. Batteries of different age or depth of discharge cycles have differing internal resistance, and a charger sees the average resistance of the pack, which may see some batteries being overcharged. The same principle applies to series/parallel connection of dissimilar sized batteries. A quality 48 volt charger pays for itself with proper battery management, and maximum battery life.
