Thoughts on this battery meter

But you can get by without the AH counter; you can't get by without the voltmeter.

I disagree. I don't use the volts display, I'm only concerned with amps drawn and amp hours removed. I know about how much I can use and if it's more than that I go looking for the problem (like when I left the basement lights on all night). I have no idea what a particular voltage reading tells me unless the batts were REALLY low for that particular day of camping. If it was a tenth or two off that wouldn't tell me anything. Yes, I've seen the SOC charts but I still look at Ah removed cause that tells me how much I've used vs how much more I can use.
