I use optimal charging to keep the upper limit at 80%. I commute 25 km one way (in sport mode, below xx kmph only ) so not much to be done about the lower limit. I usually end the day about ~25% and charge daily.
I’ve also read that time is a big enemy too.
So I am going to rely on following the good practices and Ather protect and ride the bike. 50 to 80% once a week would barely get me to work ! with option 2) I could manage two days
