It’s just one data point but I have been going months at a time with lfp’s charging to just 55%. Then I spent some time running the lfp’s down to 0 and charging them to 100% to let the BMS re-calibrate. Same difference. The BMS never really got very far off track from the 55% charging…I certainly wouldn’t let a big conflict erupt over my desperate need to charge to 100% once every week religiously…
