Used "HiLetgo LCD Digital Ammeter DC 6.5-100V 0-20A" to see if the LiFePo4 batteries I bought fit. This meter did an excellent job of showing me that from a 153 watt-hour spec, I could expect about 145 watt-hours of total energy. I couldn't figure it out without a glucometer. You have to read the instructions several times before you understand exactly what is meant. Watt-hours are stored in non-volatile memory and persist when power is removed. However, the white hour counter is easily cleared by pressing and holding the small toothpick button until the word 'clear' appears, then a quick press, 2nd press and release again resets the white hour counter to zero. Easy to do after reading the instructions for a while. $12 is cheap for what you get and I would happily buy exactly the same thing again.
