Yes, Trimetric won't compute Peukert and thus will be same inaccurate - under heavy loads - as $30 meter. I prefer paying more for quality products over Chinese cheap knock-offs, but in this case I don't see Tri being that much better. Could still pay more for a "real thing" if this was something more critical, like solar controller - but meter is just a meter, it won't make you a single milli-watt-hour of energy.
I wonder whether Tri or Victron have that 20% losses correction for charge going in/out, i.e. you take 100 AH out and have to put 120 AH in. This is how any battery works, they all have losses. I recall people complaining on Tri going to 100% and keeping on counting to 110-115, just like MrWiz described with his cheap meter.
