Would a 18.15 mA, 3.2 V solar cell have a strong enough output to charge 4 1.2 V 400 mAh batteries?
I'm currently working on a project that uses 1 Solar Yard Light cell to charge up 4 SYL batteries and am not sure if the cell, (rated at 3.268 V and 18.15 mA), would be strong enough to charge up 4 SYL batteries. The batteries are rated at 400mAh capacity; Fast Charge Rate is 400 mA; Standard Charge Rate is 80 mA.
Also, could I just wire the cell directly into the battery pack or would I have to wire it into the circuit board that came with the solar cell?
Any help on this subject would be very much appreciated! :)
