I am hoping someone can help me with this. I am upgrading from AGM batteries to lithium batteries in my fifth wheel camper. I will be adding 600 watts of solar panels. I will be adding a 50 amp Victron solar controller. My camper already has a 2000w inverter. There is a 300w Class T fuse from the batteries to the inverter. I do not know what size of bolt on fuse I need for the new batteries. There will be 2 206 amp hour lithium batteries. If I understand this correctly I need to put a fuse on each battery. I just don't know what size of fuse. The wire is 2/0 gauge. Thanks in advance for the help.
