Look at the Blue Sea dual terminal fuse block. Bolts right on the battery, has 2 fuses (check what sizes you need) and is tested/approved

What in my system would determine what fuse I get? Is it the battery or the charge controller? I have a 12V sealed lead acid 35 AH battery. The charge controller is 10 Amp.

the fact that your battery has 35 amp hrs of 12 volts, is why you need some sort of fuse or breaker between it and your load. you can use a simple in line glass or blade fuse or a resettable breaker. preventing arc's and fires.

I once had an AGM battery hooked to a light, something fell and pinched the wire together and the wire insulation melted off and turned bright red, ruining the carpet and setting it aflame. I cut the wire from the battery and use a fire extingusher, making an even bigger mess. learn from our mistakes or learn it the hard way. but don't burn the house down.

I hear ya, don't want to cause a fire. I have researched it and am going to get the fuses today. It took a bit of research to find out what type I needed for my little system. It really is just a small, portable (all hooked onto a dolly) beginner project. And I am very thankful for the advice, esp about the fuse and safety.

Last thing any of us want is a fire, next is to get that battery fully charged and floating. I am no expert, but I know who I think is/are, and I always read their comment's first. Yes yours is a small system, but can still cause a big problem. You and I are both learning and that is a wonderful thing.
