Dear Mr Singh,
As already informed over email to you, these batteries are not drone batteries. These are regular LiPo batteries with a maximum discharge current of 2C, and charge current of 1C. Using them on drones cause irreversible damage to the battery.
Drone batteries have a high discharge rating, and can be found on our store. I am not sure how use of a product beyond its scope by the customer makes our company unethical. Good Luck with your future endeavours.
