LinkPro settings for Lithium batteries
I just upgraded from lead-acid to lithium batteries in my RV. I am wondering if anyone can recommend new parameter settings in the Xantrex LinkPro battery monitor for lithium chemistry. Surprisingly, ...

Been dare done dadt….Switched to LiFePo4 from former two 6v GC’s…
Had a Xantrex LinkLite (same as your’s minus history feature) that was uber reliable up until I switched to LiFePo4 chemistry…
At this point, no matter how I programmed it (even using competing Victron’s own meter settings!!) it would not properly track Lithium more than about one discharge cycle due to extreme meter drift… meter re-syncing did no good…In the end (Ugg!) I swapped it out for a Victron BMV-12 (or equivalent Victron Smart-Shunt) which did the trick - tracks nearly perfectly with no discernible meter drift whatsoever, regardless of how many times the batteries are cycled (typically 4-5 times before opting for a full 100% re-charge, meter re-sync, and cell balancing regime)…
Lesson: Unlike wet-cells, a capable ‘LiFePo4’ SOC Meter parameters will include voltage tracking, coulomb counting, and an embedded ‘look-up’ table to accurately arrive at state of charge…
