Just looking for a tiny battery fuse for my car. I have dual batts that have a display in those carling switches. But I want another voltage display where my load is to measure voltage drop. I don’t have anymore room for carling switches and I don’t want to run a full size gauge. Is there any other options rather than those cheap ebay units like 1” round. Plan b is as my boost/egt gauge does have voltage display but its not ideal. 5c sized or smaller would be great.
