While this is a response to an old thread, I think it's relevant.
I just received a marketing email fro GeekWorm that includes a discount on
their X1203 5.1V 5A UPS Shield for Raspberry Pi 5 Series
Regular price: $46.00
Sale price: $41.00
Overview:
X1203 is an innovative uninterruptible power supply (UPS) expansion board
designed specifically for the Raspberry Pi 5B. With its advanced features
and robust power backup capabilities, the X1203 is perfect for even the most
demanding Raspberry Pi setups.
Reliable Power Backup: The X1203 provides a stable 5.1V 5000mA power backup,
ensuring uninterrupted operation of your Raspberry Pi. Whether you are
running resource-intensive applications or powering multiple peripherals,
the X1203 delivers reliable and consistent power supply.
Enhanced Power Management: One of the standout features of the X1203 is its
enhanced power management system. It intelligently monitors the power status
of the Raspberry Pi and automatically cuts off power when the Pi is shut
down. This helps optimize battery life by entering an ultra-low standby
power consumption mode. It ensures efficient operation and maximizes the
lifespan of the UPS battery.
Seamless Power Switching: Equipped with AC power loss and power adapter
failure detection, the X1203 seamlessly switches to backup power in the
event of a power outage or power adapter failure. This feature guarantees
that your Raspberry Pi remains operational and protected from unexpected
power disruptions.
Convenient Features: The X1203 offers convenient features such as auto
power-on, enabling your Raspberry Pi to automatically boot up when power is
restored. It also supports full power-off from software, allowing you to
safely shut down your Raspberry Pi without manual intervention.
Fast Charging: With fast charging capabilities of up to 3000mA, the X1203
ensures quick recharging of the UPS, making it ready to provide backup power
whenever needed.
Flexible charging:
You can use either type-c or DC5521 to charge the battery. When using type-c
you can use the PD27W power supply that powers the Raspberry Pi 5, when you
use the DC5521 you can use a variety of power adapters in the 6-18V range.
Versatile Design: The X1203 is designed to be attached on bottom and don't
use the 40-pin header, enabling easy stacking with other Raspberry Pi
accessory boards. This versatility allows you to expand the functionality of
your Raspberry Pi and create enhanced applications tailored to your specific
needs.
Seamless Data Backup: The X1203 is compatible with our range of storage
products, providing seamless integration for safe and reliable data backup.
Your valuable data remains protected, even in the event of a power failure.
Enhance the reliability and performance of your Raspberry Pi 5B with the
X1203 UPS expansion board. Experience peace of mind with its advanced
features and robust power backup capabilities. Trust the X1203 to ensure
uninterrupted operation and safeguard your valuable data.
Warning:
When you use an external battery box or battery pack, please pay attention
to the positive and negative poles, generally speaking, the red wire is the
positive pole, the black wire is the negative pole

Our club is in the consideration mode for a Pi based packet system with expansion to a VHF an HF RMS. The site has a generator for backup but I know generator power can be dirty and not immediate. We have a 50 amp Astron and I would like to run the Pi from that. Not settled on the verson of Pi but both Pi4 and Pi 5 are in consideration.
So, what would be the recommendation or success stories with a hat based UPS in the pie and what is a good way to power it from the 12 volt Astron?
