Nothing wrong with load testing the 12 volt starting battery as the OP says he intends to do. If the 12 volt battery is bad then replacing it is fine (even though it may still be under warranty). Sometimes your time is worth more than the pain it takes to use the dealer, particularly if it's the daily driver and you can't get dealer service for two weeks or more.I wouldn’t mess around with E torque under warranty! We’re not talking about a conventional system here. Plus you’re under warranty. Once you start doing O’Reilly auto zone stuff the dealer will freak out and could possibly void your warranty. E torque is no joke. There’s a generator, cooling systems and a expensive 48V battery Involved.
The 12 volt and 48 volt systems are entirely separate on the E-torque. If it's a cold start problem on an E-torque, it's a 12 volt battery problem. If it's an ESS problem then it's time to look at the 48 volt and time to take it to the dealer for warranty. Which is 8 years / 80k miles on the 48 volt battery system.
