That sounds really dodgy.
The battery seems to have at least one weak cell. I’m surprised the ECU can operate at 6V.
Running voltage is def too high. Mine shows 14.2 on lead acid 14.4 on lithium.
Disconnect the bike battery and try it with jump leads to the car battery. That should prove if the alternator is ok.
It’s possible the weak battery allows the charging volts to surge. But as you say over volts will kill a lithium.
