I agree - I wouldn't need that many and was considering the bus bar first as I prepare to do a second battery install. But, I ran across these on the internet and they look pretty cool. My first thought is that it would result in one solid block of aluminum fused on top of my battery! Maybe you could just put electrical tape along the inner edges of the blocks
There's no way that you need enough extremely high current connections to justify that fire waiting to happen. How would you even safely disconnect them to change a battery or do other electrical maintenance?
I agree it looks like a ridiculous proposition but, I'm a newbie to electronic outfitting an overlanding vehicle. I have the 2nd battery kit that I will be installing in a week or two, and I'm trying to plan ahead. I don't have crazy plans for this rig: winch, lights up front, stereo amp, inverter, and a plug in the back for a cooler (not refrigerator). There is currently a little parasitic draw (from the alarm/remote starter probably) that I'm going to solve along the way. I was also going to add a battery disconnect switch because the truck does sit some times for a couple of weeks between uses. I'm blessed to have a daily driver LX450 and a land cruiser for more fun offroading.
Well you should make things easy long-term and put another fuse box/relay box under the hood and another fuse box in the cab. Keep your after market wiring out of the stock stuff and put a disconnect from your rig so you can cut full circuits out of the equation should you need to get to basics to get home. Run a line from your battery with a fuse or circuit breaker as close to the battery as you can. Then run that you your separate fuse/relay box. Do the math and make sure your fuses match the loads and label/document what you run.
It's a good time to separate out your stereo circuit and run it on your own fuse box since after market stuff likely draws more than your stock wiring is designed for.
Running heavy gauge wires off a battery terminals with no fuses is the easiest way to burn down your rig. It’s lazy. Run a 500 amp fuse for your winch. Then another wire for a sub bus bar probably with a 50 amp fuse. Also what a pain if you ever need to change a battery.
