About the Victron 150A Dual Terminal Stud M8 Bus Bar
The Victron Dual Terminal Stud is a simple, heavy duty connection point for joining two battery cables in a compact space. Each stud accepts an M8 (5/16") lug like our 5/16, so you can extend a cable run, add a second connection to a battery terminal, or create a junction point between components without bulky hardware. It's rated for 150A continuous at up to 70VDC.
Construction and Materials
The bus bar itself is a removable tin-plated copper strip that bridges the two M8 stainless steel studs. Tin plating prevents oxidation and maintains a low resistance connection over time. The base is glass-fiber reinforced nylon, which is impact resistant, vibration tolerant, and electrically insulating. The stainless steel studs and hardware hold up in marine, outdoor, and engine bay environments where corrosion is a concern.
Common Uses for the Victron Dual Terminal Stud
This is a purpose-built component for situations where you need exactly two connection points on a single bus. Use it to add a second cable to a battery post that only has room for one lug, to create a splice point in a cable run without cutting and crimping, or as a compact distribution point in a small battery system. It's commonly found in RV and marine 12V setups, small solar installations, and anywhere space is tight but you still need a solid, rated connection.
For larger systems that need more connection points, see the Victron 150A Bus Bars available in 4, 6, 10, and 20 terminal configurations.

Frequently Asked Questions
It gives you two connection points on a single mountable base. The most common use is adding a second cable to a battery terminal that only has room for one lug, but it also works as a splice point in a cable run or a compact junction in a small DC system.
The studs are M8 (5/16"), so any lug with a 5/16" stud hole will work. Match your lug to the wire gauge you're using.
The tin-plated copper strip bridges the two studs so they share a common electrical connection. If you need two isolated connection points on the same base (for example, a positive and a sense wire that aren't bused together), you can remove the bar.
Yes. The stainless steel studs resist corrosion and the glass-fiber reinforced nylon base handles moisture, vibration, and temperature swings. It's commonly used in marine 12V systems, RV builds, and outdoor solar installations.
This is a two-terminal stud for simple point-to-point connections. If you need to distribute power to multiple components from a single bus, Victron makes 150A bus bars in 4, 6, 10, and 20 terminal configurations.
Each set includes one red block and one black block, so you get both a positive and negative connection point. One set is typically all you need per connection location.
