* According to Gobel Power test, LSEV+ and LSEV cells have almost same performance, LSEV+ cells are just better than LSEV cells in appearance. We do not provide LSEV+ cells.
* Considering officially released intact QR cells with poorer performance, we decide to stop providing EVE ESS/LSEV grade cells. We only provide HSEV cells.
