I have multiple connections I'm trying to make on my positive battery terminal. If I include the two connections the RV manufacturer made, the solar connections, inverter connections, and possibly others, the available real estate is getting very tight. I'd like to run one connection from the battery to something like a 12V buss line, but can't seem to find a 12V buss that can handle heavy gauge wire that is needed for some of these connections. Does anybody have a tidy solution?Thanks,Jim

Go to your local electical store and they should be able to help you out. No Lowes or Home Depot but a real electrical store.

Something like this might work: AmazonLooks like you might have to drill some holes for larger bolts to accommodate larger cable. But the bar is .25 thick

I use one of these Single stud junction blocks.I actually use 3 of them in my setup. 2 are used to combine the solar panel inputs in parallel and then one is used in a weatherproof box near the battery for exactly what you are talking about. All the inputs/outputs go to it and then it goes to the battery.If you want to see how I used them/them in action here is my solar install which features pictures of them.

Is something like this what your looking for?https://west.nedco.ca/lug-mechanical/burndy/bibd2-04mt/bibd2-04mt-14-2-0-insul-tap-conn/product/BURBIBD204MTThese can be found at your local electrical supply house. Or google insultap for other sizes.

I would be careful however not to introduce different charging length paths from your charging source when feeding multiple batteries. You want each battey in your battery bank to use the same charging path lengths to insure each battery in the bank gets the same charging current when being charged. Otherwise some batteries will charge differently than the others which may result in poor performance and eventually do harm to the battery. This is very important for getting long life out of your battery bank.

Just some of my thoughts

You guys are fancy, I just used a steel plate with two drilled holes one attaches to the battery post the other I insalled nut and bolt to attach extra cables from my inverter, and generator.

That's a grounding bus bar. It will accept maybe 6 awg wire. We're talking 2 awg and bigger.

OK...maybe THIS. Or add THIS from the same grounding bar page. Either of these would add 2/0 connectivity to the ground bus bars.

Home Depot has a number of choices of bus bar at reasonable prices...search their website for grounding bars.

This one is $7.83 with free shipping to store...

Sure thing, just make sure the lug bar can handle the amperage.
For sure. I would use the crushed copper tubing and drill a few holes.

All kinds of goodies can be found at a marine supplier like defender.com or westmarine.com Defender likely to have more at better prices.

Wow, nice setups! I have a very low current setup and just used breaker box ground connectors that I happened to have. Like this - unfortunately high priced but mine were spares from a new sub box I had.
