Power/voltage/current meter for a Portable Battery Box Project

I was looking for a power/voltage/current meter for a portable battery box to be used when I operate QRP from local parks picnic bench style. The "power box" would be able to power whichever radio I used:  KX3, FT817, or FT891. I will be using a BioEno 12AH battery(s). The cumulative energy measurement was one capability I wanted.


1. Large Panel-Mount Digital Power Meter - 6.5V to 100VDC up to 20A
It even does some calculations like Watts and cumulative Watt-hours. There is a small recessed button to reset the cumulative measurements.
