Features

  • Multi-Port Design for Accessories Each terminal features multiple connection ports, letting you securely attach aftermarket car audio amplifiers, LED light bars, winches, and other 12V accessories directly to the battery post. No more splicing or searching for ground points just insert the wire into the correct slot (fits 0 to 10 AWG) and tighten with the included Allen wrench.
  • Built to Resist Corrosion Constructed from high-quality brass and copper alloy with a silver-plated finish, these terminals resist rust and corrosion far better than standard lead or steel connectors. The included clear plastic covers add an extra layer of protection against moisture and dirt, making them ideal for marine, off-road, and outdoor applications.
  • Fits Standard & Undersized Posts Designed for SAE/JIS Type A top-post batteries. The positive terminal is slightly larger than the negative for a correct fit every time. Includes brass shims to snugly fit undersized or worn battery posts no more loose connections or struggling to force a terminal on.
  • Works with 0/2/4/6/8/10 AWG Cables Each port accepts a wide range of cable gauges from 0 AWG for high-amperage winches down to 10 AWG for smaller accessories. Ideal for cars, trucks, SUVs, boats, RVs, tractors, and off-road buggies. The multi-directional clamping design holds wires securely without crushing them.
  • Complete Kit with Lifetime Support Package includes 2 terminals (positive & negative), 4 insulating clear covers, 2 brass shims, and a hex wrench. Backed by our responsive customer service if you have any fitment questions, just reach out. Designed for a secure, worry-free connection that keeps your electrical system running reliably.

  • Sleek Looks & Maximum Versatility – Perfect for Multiple Battery Inputs. Sleek Looks & Maximum Versatility – Perfect for Multiple Battery Inputs.
Color: Silver
If you are running a high-demand electrical setup with multiple accessories, standard factory battery terminals simply cannot handle the load. These SUNMORN battery terminal connectors are an outstanding upgrade. Not only do they look incredibly sharp and professional under the hood, but they also offer an exceptional range of gauge options, making it a breeze to cleanly connect multiple power inputs directly to your battery. Key Highlights Massive Multi-Input Capability: With dedicated ports that accept 0, 2, 4, 6, 8, and 10 AWG wire, these terminals allow you to run heavy-gauge amplifier lines, winch power, or secondary charging circuits without a messy stack of ring terminals. Premium Styling: They look great once installed. The clean, machined finish adds a high-end, custom look to the engine bay that instantly replaces ugly, corroded factory hardware. Rock-Solid Clamping: The set screws lock down tightly on the wire conductors, ensuring a highly secure, low-resistance connection that won't vibrate loose over time. Clear Identification: They are clearly marked for positive and negative posts, ensuring a safe, straightforward installation process. Performance & Installation Installation is incredibly clean. Instead of crimping multiple large ring terminals together onto a single post, you simply strip your power cables, insert them directly into the correctly sized terminal ports, and torque down the hex screws. The terminal clamp itself grabs the battery post firmly with even pressure, ensuring excellent conductivity for clean power delivery. The versatility of having so many different gauge sizes in one block makes organizing your auxiliary wiring layout simple and professional. ... show more

  • Broke? Don’t fit? Read this.
Color: Gold-2
Guilty. I read reviews and still took a chance. But, it was my error. See, these terminal connectors are two sizes and they are labeled (+) and (-). I didn’t realize and I broke one, just like others commented, trying to spread it open to fit it on the terminal. The positive is slightly larger in diameter than the negative. Glad it came with 4 because once I realized, I was fortunate to have two more to correct my incompetence. Once you put the correctly labeled connector on the correct terminal, they fit just fine. Even come with terminal shims to shore up any play or looseness. I’d recommend not trying to spread them open for more room to fit. Just put the correct ones on the correct terminal. Quality is good. Wire connections are really good. They look good and they work. No issues with conductivity. I paired these with upgraded 2 AWG battery cables. Handled it everything. ... show more

  • Decent product
Color: Silver
I have these on several vehicles, and my boat. The multiple connection points work great for adding electrical accessories and aftermarket car audio components. they've also came in handy to replace bad OEM pre-made terminals, popular on so many vehicles these days, that have enough wire to cut off the old terminal and install these in their place. For marine use, plan on replacing every two years if in freshwater, or once a year in a saltwater application. But they're cheap enough that replacing them is just a drop in the bucket compared to what we spend on our boats. For automotive, they'll last a little longer, but they will start corroding after a couple of years. A little terminal protectant makes them last longer. ... show more

  • Decent purchase would buy again.
Color: Silver
They're very solid connectors fit and worked great It's kind of a pain in the backside to tighten them down with a 916 and an Allen wrench. Pay attention because they are positive and negative Sensitive.

  • High quality
Color: Silver
Really surprised by the quality these, I had a loose battery cable and these fixed it right up very easily, they clamp very tight to the wires and have room for some accessories to attach.

  • Heavy duty! You won’t regret it!

I’ve bought several different versions of battery terminals and they all have been kind of flimsy..but these, WOW! Nice large holes for heavy duty winch wires etc.
