The ProSportHD 12 Dual bank 12 Amp fixed charger is prewired for easy installation and is 100% waterproof and saltwater tested. Its exclusive microprocessor and software ensures that all of the available charging amperage is fully utilized to meet the unique demands of each onboard battery and charge it in the most efficient way. After the batteries are charged, the ProSport 12 monitors and maintains the charge only as needed—reducing its AC power consumption. Connection to shore power is made easy by the included 10A plug. The “System Check OK” and “Battery Bank Trouble” LED indicators are exclusive to the ProSport line and confirm the system is operating properly or help shorten any required time spent troubleshooting. Compatible with flooded and AGM batteries, this smart charger provides three charging modes plus a storage recondition mode which helps extend the life of your batteries. Because this charger is waterproof, it can be installed almost anywhere on the boat. All of these features come in a charger that is 40% lighter than conventional epoxy filled (potted) chargers.
