Solid, heavy-duty build! The quality is top-notch, and it feels incredibly durable. Perfect for battery, solar, or automotive setups. Best I’ve used so far in my VanLife rig.

These are good bus bars. Worked very well for connecting my RV batteries in parallel. It would be nice if there were a plastic or rubber cover over the exposed contacts, but that is far from a universal feature.

I used these bus bars for part of my solar system. The are solid and should last a long time. Honestly, I've bought several of these from different vendors that have all performed well. I think these compare very well with the others. The biggest difference is price and these seemed reasonably priced.

These bus bars are bigger than I thought when looking at the ad! I really need to read measurements first haha! But overall very nice quality, thick metal, tough studs for attaching wires and it's all isolated from surrounding metals that you might mount these to!Overall pleasently surprised!! 5/5

Extremely heavy duty. I've used a lot of bus bars building solar power systems and I was impressed when I opened the box with these in it. They're about 50 percent larger than the standard bus bars and are made extremely well. When dealing with high current there's no room for short cuts, I have no problem recommending these, they're much better than most you'll find.

Surprisingly nice bus bar for the price. I needed to replace mine in the boat and this one feels much higher quality than the current one I have. Tinned copper and stainless steel so it should last a very long time even in marine environments.

I've got a solar set up that I'm expanding and you always seem to need more of these. This is rated at 250 amps at 12v but the cover states 250 at 48v. Either way I'm not getting near 60 amps. I've got 2 100ah batteries to hook up to a solar panel control panel and an AC converter so this should be just fine. Standard bolt sizes and mounting screws are included. They feel heavy, the covers are tough enough and this set is good because you can remove the cover without removing the install. I only wish the screw covers were red and black, but that's just me....Overall: These are a good quality build bus bar set that make increasing your set up easy.

Got these bus bars for a small project on I'm working on that requires some considerable amount of power coming from a 12 volt power supply that will power up a 100 watt RF amplifier. These are a bit overkill especially when I'm only running 3x 50 watts and 1x 110 watts mobile radios.Nevertheless, I rather go too big than too small where it can't handle the amperage and start to heat up. The studs are 10mm in diameter and it comes with a plastic cover and 2x black plastic acorn nuts to hold down the safety cover. So far so good, they work and there's no temperature change when using the bus bars to power all my radio equipment and amplifier.
