Loud battery thumping even while driving

[MrFusion]

So we’ve all heard the various clunks and thumps from the battery while charging, but is it typical for these same type of noises to be heard while driving? I just noticed this during the last week while on a road trip that there is the occasional loud clunk that you can feel inside the cabin while driving. If I didn’t know better I would think I had run something over or something struck the bottom of the car.

After Supercharging? I've heard that, just the opposite of the Supercharging thumps, where the metal cools down and contracts making a sound. Nothing to worry about, but I do initially think I drove over something too.

It also has to do with elevation changes. Were you perhaps driving through some large hilly/mountainous areas?

I’ve heard this several times while driving. Sometimes it’s quite alarming.
