A charging port right on the pack is a good idea, you can actually get AA li-ion batteries with usb-c charging (and power step down to 1.5V).[1]
Also nice for these large batteries that you can use them to charge stuff as well. I’ve got a bunch of Hitachi li-ion power tools, almost 10 years old and the charger for that doubles as a usb power source when a battery is installed[2], but it’s nicer to have the output on the battery itself.
V-mount camera batteries often have USB ports for power out as well. These batteries are really nice for robotics projects as they come in a variety of sizes and an extra 5V power supply always comes in handy[3]
