Due to the bad weather I did not fly for a couple of weeks. I left my 2 TB47 and 2 TB48 "SMART" batteries in the DJI Charging Hub, assuming the over/under charge feature of the SMART batteries would ensure that the batteries would be left charged, at least up to 60%. This weekend I wanted to fly with my Inspire-1 and checked the batteries. All 4 SMART batteries (that are 6 months old) were bricked!!! Under European Cosumer Law, DJI has to replace the batteries at no charge since a consumer may expect that a SMART battery of 6 Months old with over/under charge protection is not to be damaged if it is left in a DJI provided charging Hub for a couple of weeks. In EU legally it is not allowed to lower the warranty period to 3 months for a consumer product. The thing is called a SMART battery and as consumer I paid 200 Euro per battery, hence i may expect more than a dumb-brick. DJI EU Support states repeatedly that DJI will not replace the bricked batteries, hence we now have a legal dispute. If my lawyer supports my believe that DJI should replace the batteries at no charge, I intend to take DJI to court as a matter of principle. For those that have a charging hub it is recommended to take the batteries out of the charger immediately after the batteries are charged.
