Battery Rating vs Capacity Monitoring
Some things: Shipping batteries in the US requires the Watt-Hour rating to be marked on the battery, and the rule is to use the "nominal" voltage. So LFP uses their 12.8v figure for that 100AH x ...

Thanks. I am still confused of course. :( It might sink in eventually.
Sorry about the light bulbs as I wrote it. what I meant was to maintain the constant amps showing on the Trimetric, as voltage goes down and the lights dim and amps fall, to get the amps back up to the constant amount, you have to turn on more lights. Not turn up the voltage.
With an inverter as the load it is hard to keep the amps constant too, but now they creep up as the inverter tries to supply the same watts to its load while battery voltage goes down. Anyway, that is apparently not related to my question about 5 amps = 5 amps.
It might be tangled up in how the shunt derives amps where ISTR a small voltage diff is across the shunt. Vague on that, but the watts showing instead of amps on the display could relate to the voltages involved there---except 5 amps is 5 amps at different voltages.
The shunt can't be not using voltage for the amps and then choose to use voltages with the same coulombs when you change the amps display to watts--or can it? Drat. Going round and around. Oh well.
