What is wrong with this Babboe/qwic battery?

In the video i say i DON'T know who makes the batteries. Now i know, probablly. On the discharge connector is says Hulong whis is probablly chinahulong.com now renamed to Jinhua Vision. Their ebike system is named I-Max and some models are named Qwic. However i cannot find the Qwic battery on their website so it might have been custom made for Babboe. Let me know if you know more.
