Not much info for something that's been out for a while

There isn't more info to provide, that's why. BATL is a PoS coin based on the Blackcoin PoSv3 codebase. It isn't meant to be bleeding-edge technology because it needs to be a reliable and dependable coin network where the dev team, and the community for that matter, are incentivised to agree to requests for modifications and/or forks which might be needed in the process of developing and releasing the commercial app.
The coin is not the experiment here, the commitment to cooperation and collaboration between a public open-source coin network and a private commercial entity is the experiment.
