I ordered on 23rd november. Received on 4th december. Feedback wrote on 11th december. I test battery by completely charged and discharged cycles 100% 3 times as seller explained on webpage. But actually lithium no need to do. All work fine. Battery came inside the small paper box included tools kit. Plastic wrap battery need to seal close. When i unpacking battery slide out from plastic. Connector line wrinkle. If damage it will be waste time for received new one. (all buyer must record vdo while unboxing everytime). One fully charged i test by continue with youtube around 8-10 hours. Someday leave it stand by mode and general use. Let's see after 3 times fully charged and discharged. Problems will happen as another buyer or not.
