Hi Guys, My 1238-6501 Curtis controller gives very different SOC % for similar voltages. For example I've recorded a pack voltage of 82.2 and had the Curtis show 22%, 31%, 43%. The pack is made up of 25 Thundersky 160Ah batteries.
With LFP cells, you can't accurately infer SOC from voltages in the middle of the range. The voltage/SOC curve is too flat.
