Charging one battery from another using a Solar charge

Even with small jumper cables, you can still transfer enough charge from a ''full'' battery to an ''empty'' one to crank an engine so the thing can resume charging itself. Or if you had one battery which was ''stuck off'' or asleep from discharge, you could get it to ''wake up'' so you could resume charging it normally.

How is the output of an MPPT solar charge controller

If your charger keeps track of the MPPT, it will not allow the voltage at the panel output to drop below 10V AND will use its built-in DC-DC converter to drop the 10V to 4V while at the same time increasing the output current to 2.5A, which will result in the full 10W of the panel''s power transferred to the cell, helping charge the cell much
