Yes the smaller 12v Aux ESS battery seems to be an issue and most people will replace that battery several times along a starter and Alternator given the strain the system puts on all those 12v parts.I know I've read numerous nightmares about the NON-eTroque‘s tiny secondary battery going bad causing havoc leaving people stranded unexpectedly but has anyone read a single negative topic about the 48v eTorque? Apparently it’s been out since 2018 according to post #148.
IMHO Its Best to have more power than less ... and also a longer (80K) warranty is a nice benefit. After that it's anyone's guess. But like with most old things you might need to get it replaced and then go another 80K miles. They might even be cheaper by then and maybe they get better ... so I can buy two and join the EV club!!!
