Review on Spartan Power Battery Multimeter 6 5V 100VDC by Brandon Burnham

I used a gray plastic wall switch housing to place the shunt. I used a dremel tool to open up the side to place the shunt and used zip ties to secure it. I mounted this box to the wall very near the connector where the negative load terminals connect with a #2 wire about six inches long. The battery wire on the other side is about a foot long. Then I used 2 two core cables with red and black wires. I used two black wires for the terminals connected to the shunt side on the battery side and one red for the shunt on the side connected to the load side of the shunt and the other red for the positive supply or the meter. . (see photos) This enabled me to place the measuring device on the wall so that it was easy to read. The readings are very accurate and show the same numbers as my Wattsup RC hobby meter.
