Does my 6v have a bad internal connection?
These are brand new 6v connected in series. Im cycling them in the garage using a 3.5a light bulb load. I had an RvWhisper batt monitor installed and noticed it was reading super low at 12.05v. ...

I'm also suspicious that the batteries aren't fully charged. By far the best way to determine charge is to measure the SG which takes the guesswork out of a voltage check.
The graph apparently shows a 4A load for 5 hours or 20Ah with batteries that are likely rated at 200Ah+ and the voltage is very low with that small load still attached. That's only a 10% discharge. Perhaps the bad terminal is a factor.
But stop the guesswork and check the SG after charging and at the end of the load test.
