Hi, I'm new to solar and I am just getting started with a renogy starter kit for my shed. I'd like to know if it's safe and doable to use a panasonic car battery 65ah. I wanted to try this first before I spend the big bucks on a solar battery. Im going to be charging ego lawn equipment batteries and my e-bike. Sorry if this is a stupid question but I'm just new and learning. Thanks for the help.
