Application for 21700 Lithium Battery For Electrical Vehicle 3.7V 3000MAH 30C
7-10 days for bulk cell base on industry pack , this is normal model , we prepare the stock continue
25-30 days for battery pack after the customer confirm the detail accessories for examples PCB Connector etc.
The period of warranty is one year from the date of shipment. We guarantees to give a ccin case of cells with defects proven due to manufacturing process instead of the customer abuse and misuse.
The suggestion for Storage of the Lithium-ion Batteries
The batteries should be stored at room temperature, charged to about 30% to 50% of capacity.
We recommend that batteries be charged about once per half a year to prevent over discharge.
