Hi. Just like in the topic- should i keep the fuse if i put a second battery in my trunk(the current wire with the fuse will be connecting the two batteries)? current fuse:200Amp...

 

im running 3 batts, one under the hood and 2 in the back of my suv. None of them are fused. I have been told many times that there is no need. batts under the hood are not fused so why fuse the back. just put the fuse on the lines from batt to amp. But the batt in a battery box just to be safe
