I am planning on building a Li-ion (cylindrical cells) 21700 battery pack for a 60V system for my future e-scooter.
And I live off-grid. Can you use a 12V or 24V solar panel to charge a 60V or 72V battery pack? I thought you have to have a solar panel (or solar panel"s") that has 72V output in order to charge a 72V battery pack.. The battery cell is 3.6V nominal, 4.2V max.
And charge time does not matter to me as I don't mind charging for a few days without using the battery. Anyone?
