Per Pianotuna:
“I do know of one case where the battery management system totally drained an Li bank and destroyed the batteries over the time frame of one year.”
I suppose almost anything is possible in ‘one case’ (or say, even several cases - ??) where a defect might be present, yet I don’t necessarily see that as an ubiquitous flaw that affects an entire genre of battery type - the literature I’ve read appears to suggest otherwise...Either way, leaving any battery unattended for a full year will not be one of my real concerns - lol!
