When using a solar panel for my spotlight cam pro, is it best to have just 1 battery or 2?

Does it makes sense to have 2 batteries in my Spotlight Cam Pro when using a Solar Panel? Or should I just have 1 battery installed only?

Hi @user31865. I have just one battery in my Spotlight Cam Plus with a solar panel, and it works just fine. The second battery would be just for backup in case your first battery drained and the solar panel was not trickle charging it.
