Lipo Rider Pro with 8v Solar Panel

I had some custom solar panels made up for a product I’m working on. After ordering the panels for 6v I put them in the sun and hooked a volt meter up. The volt meter read 8v…

Will this fry the Lipo Rider Pro if I try it? I think think this is called the “open circuit voltage” so perhaps the voltage will drop when it’s actually connected.
