I have just published a short video on how I setup for powering my portable ham radio station.
The video above does not go into great detail about how important a revolution the LiFePo4 battery is. These batteries have around twice the energy density of a Lead Acid battery. They have a flat voltage discharge curve and they can be recharged around 2500 times. LiFePo4 batteries are more expensive and require a different charging system they are revolutionary for portable operations.
This system is larger than I would need for a POTA activation or the like. It is intended to be setup for longer term deployments, with multiple radios and more.
