You have the right competence and you did a great job in diagnosing the two problems the battery had, and made a great show of skills by mending the whole battery.
When you bring a car with a battery problem to a dealer, they can only replace the whole battery, even if the problem is one of the BMS chips - usually some OP Amp - which costs few pennies.
My compliments.

great video. Megger is a brand name. In Avionics we call the test you are performing an insulation resistance test.Perhaps best to use a CAT4 insulation tester on a high voltage high energy system.

Good job guys. It's great to see the training we have done put into real life practice.

Third tested megaohm , wire airgap is not big enough . Same for some ground . This would cause intermitant issue . Just put wire size distance , problem solved . This issue broke the battery . Nice work

Where are your safety glasses?

Curious what mileage and state of health car is at? (My 2017 40x only has >20k on it so far), is this a common issue with age or mileage or hot climate or just unlucky etc. Happy my SOH has remained at 92% since buying, only dropping 0.4% over 7000km and 16 months.
