I just passed final inspection in California for my Pytes E-Box 48100R and Sol Ark 15K combo, both the Pytes and sol ark tech people are telling me that keeping the batteries at 100% SOC for prolonged periods of time is just fine. I had built my own 16s lifepo4 with raw cells and kept it cycling between 20% and 80% SOC for the health of the batteries and also for the longevity. So my question is, has the conventional wisdom changed about this topic?

I just saw this thread and even though we talked about it, I thought I would document it here for the benefit of other readers. Nothing has changed about the conventional wisdom. 100% on my Pytes is actually a cell voltage of 3.5 according to the USB console monitoring I have been doing. My batteries begin discharging at 4PM so worse case they are at that voltage for four hours since they are usually at 100% by Noon. If you want to adjust it, change your percentage to 95% at 1PM but remember that Pytes recommends going to 100% occasionally to rest the SOC colomb counter. On days like today mine went from 45% to 100% by Noon.
