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.

I understand the question, but another factor is how much 6s gas, especially older ones like mine (5 years)
I found in summer on solar with long sunny days in a row and set to 14.8, that the batts got to 14.8 mid-day so that left a long time still to go in daylight at 14.8 while amps tapered. I was losing "water" more than I liked, so I dropped to 13.6 soon after reaching 14.8.
The batts still got to full that day as measured by hydrometer, but did not lose nearly so much water per week.
A side note-- my old rule was they were at 90% SOC when amps had tapered to 5 amps per battery at 14.4/5 volts. When I increased charging with 14.8v, the amps per battery at 90% was more, but I didn't have a measurement. I have enough evidence now to use 8 amps per battery as my new "marker" for when to stop the gen at estimated 90% SOC instead of 5.
Essentially that means the taper curve is steeper with 14.8 getting to full but by the time you are at 98% or so nearing 100, the amps will be so low the amps difference will be small between 14.4 and 14.8 by then.
