I'm looking for help determining what size of solar (PV) I should use to recharge my Li-po battery after discharged.
Battery Characteristics :Capacity:1600mAh
Nominal Voltage: 3.7V
Charging Voltage: 4.2V
Charging time (std):6 to 7 hours
Charging time(max): 2 to 3 hours.
Solar (PV) I have looked at a couple solar cells like the Digikey solar SM101K09L. This is a MONOCRYST SOLAR CELL 198MW 6.22V can anyone help determine how long it would take to charge this battery with the solar cell I have mentioned above? Is there any other product you would recommend?
