Pops/Bangs/Humming Noises

[dubs]

I've heard a few pops/bangs and humming noises coming from my battery? should i be concerned? Like somebody was hitting the bottom of my car.

Totally normal.

If it starts talking dirty, well then you may want to worry.

Yeah I dunno what happens with relays specially during software updates. They have a symphony!

Mine also does this. I reckon as long as I don't see the magic smoke, its all good.

It'll happen at any time. It's jarring and used to be very concerning as it doesn't sound that great for the car. You'll get used to it over time. It happens with my 3 and also now with my Y - metal contracting and expanding as the battery cools and heats. You're also bound to see it happen during supercharger sessions, particularly if ambient temperature outside is cooler.
