“ But a cheap coulomb counter is fine with me because it's an inherently unnecessary device.”
Ok, but for clarity it should be noted here that a meter that only counts coulombs is not structly compatible with LFP, though it may be fine above 50% SOC - in practical terms with LFP, SOC only begins to get important below 50%...
As has been already noted here several times, computing SOC with LFP requires a sophisticated algorithm including a ‘look-up’ ledger which is necessary when below a 50% SOC...This is due to the extremely flat voltage curve characteristics of LFP, and why (as previously stated) I had to ditch my former meter...
