The seller is really good and I buy here so often... but I don't recommend these Lipos. You can just take a look at the attached photos. You will see the internal resistance is too high and cell voltage is so bad. It should be less than 10mR and 4.20V accordingly. But there is 40mR and voltage 4.14-4.20. Also, after the flight, I would say that the batteries work like my old one after two years of use. Flight time is 2-3 minutes instead of 4-5 like on a good one. FeiYing store doesn't trust my measurement, unfortunately, and won't do anything. I just asked to check the other pcs from the same consignment.
