Tear downs of both show identical external case and internals are the same.
Have read a few posts on reddit of some saying they had contacted Ecoworthy with issues and had DC House added to the e-mails for resolution. Also read they were the same e-bay store a few years ago.
So while probably not the same company, most likely sister companies that either buy the batteries from the same supplier for bulk discount and slap their own stickers on it or one or the other is the actual manufacture and the other buys from them.
