Thanks Phil for the informative reply. I plugged in immediately when getting in the driveway and waited a couple hours before unloading, chain sawing and splitting the wood (with an electric Worx chain saw and Swisher electric log splitter). Last time I charged to 100% was at Cocoa Beach Florida in October. Some EVers told me to just charge to 80% like I normally do and others say to charge to 100% after a deep discharge- so I split the difference and charged to 90% :-) Next time I’ll charge to 100% is when going to Gatlinburg, Oak Ridge Tn and Mammoth Cave Ky in February. Stay Charged, Mark

The "battery damage" comes from the fact that Tesla's BMS on the 3/Y are somewhat parasitic, and continue to suck power from a discharged pack. There is added degradation from time spent at low SoC, but not "damage". You do not need to do a balance charge often. I'd say 3 to 4 times a year is sufficient, just do not let it sit at 100% after this charge. Plan to drive it soon after it finishes. LFP is less susceptible to this kind of degradation, but it still happens.
