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.

the only problem i had with mine, was i tried to calibrate at low amps
and threw it out of whack
after i reset it, and left it alone it has been find
last week, i noticed, i was having problem returning full amp hrs,
charging was tapering before ampHr capacity had returned to the set amount
but it was not the meter, it was the batteries
after i zapped the batteries at 15.4v for 15 minutes, they accepted the ampHrs and recharged to the full capacity count and reach the 1amp per battery at 14.4v, that is my indicator of full charge
it was the batteries not the meter
its a straight matter of Physics and chemistry
if you remove 100ampHrs it will take 105~110 amphrs to reach full 'SOC Chemical balance'
this meter will Not indicate going over aka returning extra (the counter stops and says XXXamphrs 100%
BUT it will indicate the amp flow, and that the batteries are still accepting amps after the capacity counter says full, and show how many amps the batteries are taking (its just the counter has stopped)
not a problem for me, i just watch the amps charge rate they are taking,
(5)AGM batteries, so when at 5amps or less at 14.4v, they are full
(2) 6v flooded GC, i would guessitmate 2amps at 14.0v means totally full
right this minute, the amp counter has returned to full capacity, showing 100% ,
BUT 14.18v, and charge rate of 4.2~5.3 amps,, I know they are not at peak SOC and have a tiny ways to go, but very very close
