Not a TriMetric, but for $20 might be worth trying out...
Bayite DC 6.5V-100V Digital ammeter voltmeter Amazon suggested this for me and I'm thinking for $20 I might just give it a try. Has very good reviews too.

Even with more professional battery monitors, The human who believes the readings without any occasional supporting evidence is misguided.
I always look for how much amps the battery is accepting at absorption voltage on my AGM.
Sometimes the Ah counter is very close, other times it drifts and I reset it.
Also of consequence is how many cycles it has accumulated without a true full charge, or in the case of my TPPL AGM, how many cycles without the higher amp recharge.
Still a great tool to have, even if I don't trust the % from full or AH from full screens completely
