Question:
Does both battery(s) pos B+ and neg B- float with no reference to the metal chassis of any of the audio equipment that is connected to the batteries?
B- is not connected to chassis?
Metal chassis would act as an antenna I would think if it was not connected to B-.
I am having trouble seeing the loop, closed circuit, to mother earth ground and back to the source, the batteries.
Test:
Measure for DC voltage from B+ to chassis.
Measure for DC voltage from B+ to metal enclosure of battery charger. (charger left connected to battery(s).)
(I assume charger uses a 3 wire cord and grounding type plug.)

Grounding Myths
4. To operate with low noise, a circuit or system must be connected to an earth ground. False, because airplanes, satellites, cars and battery powered laptop computers all operate fine without a ground connection. As a matter of fact, an earth ground is more likely to be the cause of noise problem. More electronic system noise problems are resolved by removing (or isolating) a circuit from earth ground than by connecting it to earth ground.
5. To reduce noise, an electronic system should be connected to a separate “quiet ground” by using a separate, isolated ground rod. False, in addition to being untrue, this approach is dangerous and violates the requirements of the NEC (electrical code/rules).
6. An earth ground is unidirectional, with current only flowing into the ground. False, because current must flow in loops, any current that flows into the ground must also flow out of the ground somewhere else.

Correct.Nothing touches a wall socket with the exception of the three prong plug that provides access to ground.
I charge when I’m not listening.
In the rare event that I want to take input from, or output to, a device that is plugged in on a wall socket, I use an audio engine Bluetooth connection. There is never a physical connection between components on battery and components on mains.
1.) I have active cables that do not work if not connected to ground.
