Putting two power supplies of different voltage together is an even more terrible idea. Either the lower voltage supply shuts off (and is useless) or it sinks current. If it is designed to sink current, it will reduce the available current from the higher voltage supply.
In general, yes you can parallel two supplies. How well this works depends on how well they end up sharing the load current. This depends largely on a good match in the output voltage of the supplies. If one is at 12.0 V and the other at 12.2 V, then the higher one will supply most of the current and the lower one will be idle.
Putting two power supplies of equal voltage together is not likely to result in a good distribution of current. Putting two power supplies of different voltage together is an even more terrible idea. Either the lower voltage supply shuts off (and is useless) or it sinks current.
The power board is connected to an external 12-24 V switching power supply. Can/should I connect the two power supplies' GNDs together? Can/should I connect the two power supply GND togheter? Yes, generally you must unless there is a good reason not to do so. But then you would know that.
Because batteries have a positive and negative terminal, they are ideal for use in dual balanced power supplies. Dual-voltage power supplies typically have a positive and negative power source that is equal in voltage value but opposite in polarity, in addition to a zero ground point midway between the two voltages.
That is because both supplies have a common ground. Series would only work to make 17V is both were independently floating, which they are not. It is not possible to connect two supplies with a common ground in series. Whether series or parallel, either way is a REALLY BAD IDEA. Connecting two power supplies of different voltages together:

I need to use a Raspberry Pi in a project. I use a 5 V power supply for it (now a 2 A phone charger), and it will control a "power board" with some MOSFETs, etc. running at …
There are two ways to wire batteries together, parallel and series. The illustration below show how these wiring variations can produce different voltage and amp hour outputs. …
$begingroup$ Welcome to the future! This answer is now six years old, and I suspect it''s no longer accurate. I have a number of 99-watt-hour lithium-ion power banks that …
No, you can''t put two supplies together in any way to add both their current rating and their voltage. This should be clear just from the power output alone. The 15 V 5 A supply can …
In general, yes you can parallel two supplies. How well this works depends on how well they end up sharing the load current. This depends largely on a good match in the …
If the two power supplies share a common ground, or can be made to, then it is no problem. However, the return wire must be sized for the sum of the 8 V and 12 V currents. ... The 82 volt battery powers the 12 volt …
This system can even support multiple power supplies and multiple batteries. Here is what it would look like: This scheme allows for as many power supplies and batteries as you want. …
If the two power supplies share a common ground, or can be made to, then it is no problem. However, the return wire must be sized for the sum of the 8 V and 12 V currents. What are the 8 V and 12 V currents, power …
Redundancy: Improves redundancy since the remaining batteries can still supply power in the event of a battery failure, albeit at a lower capacity. Reliability: Because it …

Yes, you can split the load between two power supplies without any issue, just …
In short – Yes, you can connect two power supplies together, but it''s not as simple as it sounds. Tapping into twice the power requires precision, the right tools, and a …

I''m trying to understand what would happen when connecting two grounds from diffident power supplies together. A more in depth explanation of what I''m trying to …
As well as connecting individual batteries together in series, parallel of combinations of both, in order to create one single voltage supply, we can also connect batteries together to create what are commonly called Dual-voltage …
Yes, you can split the load between two power supplies without any issue, just be sure to track how many amps each is providing. This is routinely done in a house for it''s line …
Charging multiple batteries in parallel can be a great way to increase your power supply and improve efficiency. Whether you''re an avid camper, a DIY enthusiast, or …
A battery technically has a positive and a negative terminal. There actually is no ground terminal. The potential across the battery is the voltage which you will see labeled. A 9V battery can just as easily be used as …
