JetCat (Germany) don’t supply batteries with any of their turbines as they can’t ship them anymore. When they could, the battery matched with EH balance plug that was pretty std in Germany, companies like Graupner used EH on all their batteries and Chargers.
All batteries I get in the U.K. now are JST-XH so I provide an adaptor lead from XH to EH if people go that way.
