Well there you go right there; tell the story of how you built this thing to support your high altitude balloon project and you'll start to make that crucial human connection with your potential customers. "Hey, I was doing this cool little project and I made a power supply that I needed for it. Then I thought maybe other people might be able to use this, so I'm selling a few to test the waters." That's *way* more engaging than just a dry technical description of what the device is, and makes ordering one seem more like an interaction with another maker and less like another soulless, anonymous transaction with the Great Internet Vending Machine.
As for the battery charging thing, you probably don't need to build it in (that way lies feature creep, and increased cost, weight and risk of component failure) but it may help to include in your story something about how you charge the batteries for your project. Maybe the answer is obvious to everyone and I'm just obtuse, (it wouldn't be the first time) but it's a question I have, so you get it as feedback for free. :)
