Should cable shields be connected to earth ground, or to power supply
The DC -Ve is not connected to earth ground internally in any power supply as far as I know. This is because you can use multiple power supplies to create different voltages,

6 FAQs about [Does the battery shield need to be equipped with a power supply ]
What is a battery shield?
The term shield comes from the marking on the board itself which reads 'Battery Shield' and it is a stand-a-lone item not designed to piggy back another board. This naming does lead to confusion... Here is a link to a single cell version: Portable Power- 18650 Battery Shield for Raspberry Pi & Arduino -...
What is the Arduino Battery Shield?
The Arduino Battery Shield is an essential accessory for any Arduino enthusiast looking to create portable and battery-powered projects. It offers compatibility, efficient power management, and an easy-to-use design, making it a reliable solution for all your battery power needs.
Should a shield be connected to a power supply?
CL. The impedance of the shield connection must be as low as possible. In general, the cable to the actual earth is so long that its inductance is too high, which results in high impedance at high frequencies. So it is likely to be a better idea to connect the shield to the power supply. CL. Thanks.
Which side of a battery is used to connect to a shield?
Generally the ground (negative side of the battery) is used to connect to the shield. However, it is important that only one side of the shield is connected to ground. Otherwise you will create ground loops which could cause strange behavior in your circuit. In the RS-485 systems I have worked on they are designed as follows:
Is there a battery Shield for Raspberry Pi & Arduino?
Here is a link to a single cell version: Portable Power- 18650 Battery Shield for Raspberry Pi & Arduino -... TK discusses a portable power supply module known as a Battery Shield for Raspberry Pi and Arduino. I also trialed by commercial power bank with an Arduino project to see what occurred:
Which battery management systems are compatible with Arduino?
There are various battery management systems suitable for use with Arduino. These systems offer features to optimize power consumption, monitor battery levels, and protect against overcharging or discharging. One popular option is the Arduino Power Shield, which is designed to provide a stable power supply for Arduino projects.
