I bought one earlier this year for another application. Seems to be performing per specs using actual data from this meter: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

I use a similar meter every time I charge my my glider's LiFePo battery. I basically monitor the total Ah's required to fully charge the battery versus the amount of time my master switch was on and instruments were powered up. Any significant change indicates either my glider's power demand changed or the battery's capacity is changing. This is a great early warning method commonly used with RC models to let you know the on-going health of your battery.

BTW: I use a cheaper brand meter (https://www.amazon.com/Analyzer-Digi.../dp/B0753DPC2D) which appears identical in function.
