Product Description

Up to 40% lighter than the previous Generation 2 Series of ProSport chargers that were epoxy filled, these latest models now feature an expanded LED display that includes a system check OK function and a battery bank trouble status alert for simplified detection of wiring problems or failing batteries.

Unlike conventional chargers that typically impose an amperage limitation per bank, the ProSport’s Distributed-On-Demand Charging Technology ensures that 100% of the available charging amperage is fully utilized to meet the unique demands of each onboard battery.

ProSport’s exclusive Sequential Multi-Stage Charging process delivers three sequenced modes of operation: Charging, Conditioning and Maintenance that fully charges your batteries while maximizing their service life. Two user-selectable performance charge profiles can be digitally selected for flooded, standard or AGM-type batteries with a third High Performance AGM profile on 20A dual bank models and color-coded programming caps, allowing the ProSport to be simply reprogrammed in the event batteries on board are changed to a different type.

Even when your boat is in storage the ProSport protects your batteries with an additional Recondition Mode that will automatically recondition all batteries for up to three hours a month, further extending battery life.
