Not if you have the right charge controller and the right Lithium 
chemistry. Buy a battery from these guys. Good folks, show up at major 
hamfests/conventions.

Buy this solar charge controller -- it's the only MPPT controller I know 
of that is RF quiet. Make sure you get the one for LiFePO4.

I charge my LiFePO4 batteries from AC using the power supply for an old 
laptop, connecting it to the controller in place of the solar panel. If 
you don't have anything suitable, buy the matching controller from 
Bioennopower.
