Very strong, easy to mount, small screws also included in mount base for add on devices like monitors, etc, plus covers to protect when open mounted. This was used to feed my solar inverter from my battery bank. It still allows me the option to add another future battery bank from the same terminials.
I bought these for my truck. Light bars, amps, winch, etc. (those battery post things just don't work for this much stuff). In any case they are well constructed and I will buy them for my boat when I get around to getting that project done. Well worth the money.
I bought these to install in the battery compartment of my RV, hoping they were big enough for everything that needs to be attached to the battery. They are perfect. They handle both large and small terminal rings.
I'm using two of these for a vehicle-based solar power installation. Great build quality, decent price. In addition to the large lugs for high-current connections, the small screws are handy for low-power connections and eliminated the need for an additional bus-bar.
