Im in USA so no need to wait for China batteries . Battery doesn't come.in a fancy retail package it it just the battery and charger. The battery comes with its own charger you just have to connect the cables as instructeded. The Battery was just tested to ensure that works and it does perfectly . I tested this battery with a 1000w ebike motor kit and it gave it lots of power so the battery works perfectly. any questions please ask . Here are the specs .
