Hello,  I recently inheretited a Matrice UAS setup with two new TB55 batteries that had never been out of the box.  Each battery flashes 1 white dot.  I plug them into the Hub and get an initial yellow that flashes one green, and then goes red.

All I can find is that this is a battery error.  I've researched everything I can find on the web.  Are these batteries really $500 each?? Please Help!

Thanks

Hi Baily, we apologize for the troubles with the battery, sold red means battery error, how about leaving it to charge for over 1 hour in case it is still in hibernation mode? If it is still solid red, the battery may have been over-discharged and the cell is broken. We recommend to use a new one. In addtition, please maintain the battery carefully, at least fully charge and discharge the battery once every 3 month, charge or discharge the battery to 50%-65% if not intended to be used for 10 days or more.

Mindy,  I will place them on charge.

It is impossible that they were overcharged as they had never been unboxed from DJI before yesterday.  This enterprise UAS was ordered July of 2019.  The individual that ordered it subsequently quit in August.  I took over his program, but did not address the UAS until now.  I noticed that batteries are only warranted for 6 months months, but these have never been used.  Who can I contact at DJI to discuss?

Please PM me.  Thank you.
