The seller did provide a response to most of my questions. The product arrived earlier than scheduled which was a pleasant surprise. I tested the unit, and it performs as anticipated per specs listed. Note to the Seller: The unit does, in fact, report negative voltages which should be stated clearly in the product description. Overall, a positive transaction!

Nice cheap battery monitor.
This is a perfect, simple, cheap battery monitor. It takes a 54 mm hole saw to install. The cord is a bit short, approx 6 feet so it must be mounted close to the battery shunt. It’s easy to setup and is back lit and easy to read. If you’re looking for a good cheap no frills monitor look no further.

Simple Accurat Battery Monitor - great for lifepo4 batteries
Provides accurate measurement of battery capacity and is particularly well suited for Lifepo4 (lithium iron phosphate) batteries. Easy to set up. Just input the amp hour rating of you battery. You must also tell the monitor when the battery is fully charged the first time you use it. It then keeps track of coulombs (amp/seconds) delivered from the battery when under load of coulombs put into the battery when being charged.Provides accurate measurement of battery capacity and is particularly well suited for Lifepo4 (lithium iron phosphate) batteries.

Just what I needed
This thing provides real piece of mind. And it is just plain cool. When >50ma is passing thru it, it slowly pulses a green lcd light and accurately counts the amps moving in and out of the battery. It seems to work very well and is a great addition to my VeeDub camper van.
