What can I say, its a shunt. Pretty simple device. Having said that, it came in great condition, was easy to install. The most important thing about these shunts is having ready access to its specifications. Specifications for this shunt were readily available on the website. I can't say that for the cheaper shunts available else where. Without the spec sheets, you can't configure your monitor to accurately read the current passing through the shunt. This one seems to be very accurate to its specs.
I have a motorhome with two deep cycle batteries for a total of 200ah. I purchased this shunt and the powermon device. I separately purchased a 100amp fuse as noted in the installation diagram as a requirement. I had my service facility install the fuse and shunt, as well as make up the necessary heavy duty cables. I then installed the powermon device and bluetooth app. Despite the extra expense for professional installation of the high amp components, I am completely satisfied with this quality system.
So far so good! Everything seems to be working as expected.
Works as expected! Good quality.
