So I want to buy another battery for my ebike, (Jasion YR20), so I can go for longer rides as the 20Ah isn’t that much when you’re not pedalling, anyone have a Jasion YR20 here and have bought a second battery the connection is pretty weird apparently I asked chat gpt with the picture of the connector and they said it’s unique which makes it hard to find a replacement.

Any help would be appreciated, the battery is a 48V 20Ah (960Wh)
