This is simply untrue.. In fact the company that physically manufacturers the Link-Lite and Link-Pro is the same company that originally designed and built Victron's monitors. Xantrex did not design nor do they build the Link-Pro or Link-Lite they simply re-brand them.
The Victron BMV-501 and Xantrex XBM Ah counters were actually IDENTICAL other than the graphics. IMHO having replaced far too many older Link 10's ,20's and 1000 & 2000's the XBM (which was not made by Xantrex, just relabeled by them) was actually the first good quality highly reliable Ah counter Xantrex offered the Link Lite and Pro are from the same origins & manufacturer as the XBM..
Yes the Victron is less expensive,
and slightly easier to install, but to say the Link-Pro and Lite are a POS is just plain silly.
FWIW I can have any battery monitor on the planet, I have 8 - 10 of them laying around my shop to choose from, and I choose to monitor my LiFePO4
bank with a Link-Pro. The Link-Pro is really quite a good & reliable product, IF you can keep up with the programming in order to keep it accurate, but this applies to all Ah counters.
In terms of Ah counters remaining more accurate for longer in regards to SOC I would have to say the new Blue Sea product has some excellent recent design tweaks that the rest of the pack does not. The chief designer
at Blue Sea has been working on this for a long time and some of the tweaks are already in the new M2 1830 SOC Meter. Is it as accurate as the Smart Gauge, not that I have seen in my testing, but it does do better, for longer, than the Xantrex or Victron's do at tracking SOC..
For instance it can track varying charge rates for charge efficiency calculations, it will look at resting voltage when it see's no current
across the shunt and then compare this to the Ah count and make corrections as needed etc.. It has more tweaks that I can't really talk about too. These are all things designed to help it remain more accurate during PSOC use, something we actually do regularly on boats, and something none of the other guys can currently do. Course all this comes at an expense and again this makes the Victron a great "value".
Still all Ah counters are very tough to keep in sync with a battery bank so the easiest SOC monitor we currently have would still be the Smart Gauge.
For someone who had an older Link that has died replacing it with a Link-Lite or Link-Pro is actually easier than replacing it with a Victron because the wiring
is already run and in place.
