This is an onboard charger for dual trolling motor batteries. It was originally installed on my Triton Boat and always worked to charge both trolling motor batteries. It was working perfectly when removed from my boat last month. I replaced it with a 3 battery charger that could also include the cranking battery that also runs the electronics.

A downloaded printed copy of the manual is included. It shows the charger has two banks of 5 red LED's and 1 green LED that each provide charging information to track the progress of the charge cycle on each battery as the voltage rises. All 5 red LED's will all illuminate in the beginning of the charge cycle and will turn off in sequence as the voltage rises, and ultimately the green LED will illuminate which indicates a full charge. Photo also shows charging status Green with one side attached to fully charged battery and other side Red as not attached.

Please note that photo shows power cord has been spliced.
