As per previous videos my goal is to have solar charging on the boat to top up the 48v LI-Ion batteries so I don't have to carry them home to charge when just needing to motor in and out of berth. The one major risk of this would be the solar controller overcharging th battery causing damage to the batteries in the best case situation or burning the boat down in worst case.
The test here is to make sure that the controller doesn't charge past set voltage even in sunny conditions over a number of days .

How has it worked in your boat over the past 6 months of winter? I don't know if you kept your boat in the water and used it over the winter, but maybe you kept the solar hooked up.
I plan to use mine to charge 58.8v EGO batteries while camping, so am wondering how close to the full 4.2v per cell this is safe to set. In my test today the display still showed over an amp output with the volts showing 58.8v. After I disconnected the volts were below 58v, so it might not have charged beyond 58.8v once current dropped to 0. I'm curious what you think the max safe voltage level is when using this elejoy? Thanks!
