You probably got this hoping to not have to bring along an external battery, but do keep in mind that even with a good internal battery you are limited to 5 watts.? If you're doing any kind of digital work, that's going to speed up the discharge.??
In my experience I have tried bringing along a 3aH Bioenno battery which has provided more than enough full power for my needs.? ?I can't say I've transmitted for hours and hours as you have, but I can say I've been able to use that same battery for multiple activations without recharging.??
Since a Bioenno battery only supplies 13 volts I've only been using it for the radio.? There are certainly times I want to bring along another device powered by USB.? I found this battery which provides plenty of PD volts to power up the radio:??
You'll need this cable for the radio:
With this battery now I have something useful both for the radio and other USB-powered devices, so it justifies bringing along an extra battery.
Of course, your needs may be different.
