So I had several people say that a 30ah would run my Livescope system for my style of fishing. Usually about 6hrs. a day crappie fishing. Now I've had several people say 30ah is not big enough. What if I added another different size (20ah) in parallel to the original 30ah giving me 50ah? Will this work? Does the second battery need to be the same size? Supposedly they would draw down at the same rate? What happens when the smaller battery runs out of juice before the bigger one?
Thanks
