Right, it lacks many features. Old school method: tape a piece of paper next to the meter showing AH removed = xx % full. I think any shunt up to 1000 amps can be used. It can be programmed for different styles.
It also has two programmable relays to start a generator or notify the user to charge or whatever. For under $90 it has its place and covers the voltage range you need.

Unless I'm missing something: - it lacks the ability to provide % of full; - it lacks a charge efficiency factor, and can thus develop an accumulated error; - the accumulated error can be manually cleared but not automatically; - it requires a separate 9-30VDC power supply, most likely a wall wart AC power supply; - it looks as though it would work with a 100A/50mV shunt, but I'm not sure. Am I correct about these?
