I was just going off his statement saying “my 42V battery pack”. There are some guys over-volting their 36V carts with either 7X 6V FLA’s or 13S LFP packs. I misunderstood his statement if he only has standard 36V FLA pack.
However the voltage doesn’t really change the output current much. A 355W PV panel charging at 42V-43V still only has a theoretical max of 8.2A and a realistic max of 6.5A so it doesn’t change much. I bet real world it averages 3A-4A for most of the day.
Not trying to be argumentative, just saying 15A isn’t feasible on 355W.
