I was having a discussion with someone on an RV forum and I pointed out that I like the AiLi meter that Will reviewed and it's fine for me because my BMS can give me SOC from my phone and the Victron Smart Shunt is just too pricey for me for what it does.
I got the following response:
Is this right? Have I missed this detail on this forum?
I got the following response:
Ok, but for clarity it should be noted here that a meter that only counts coulombs is not strictly 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
