    New TB47 battery upon opened it was a bit warm. I did not think anything wrong as they sometimes are a bit warm on discharge.. Tried to plug to charger and it does not charge. Just one lED blinks twice and then goes off. Charger works with all other TB47/8's.. I will send back to retailer but wanted to know if anything can be done...

    Hey, have you tried upgrading the firmware on the battery? I had this happen too, and I was about to send it back to DJI until someone recommended upgrading the firmware on the battery and it worked...

    Agreed,try updating the firmware. I read somewhere that an older firmware that Dji released caused problems with batteries charging,so updating your firmware could correct the problem.

    sounds like you may have a dud if you cant even update it in the inspire...I'd send it back.

    Which LED is blinking twice? Have you checked against the error code/charge protection LED display?

    Yes, they just did! Let's hope I don't get another dud...
    It was so much easier with standard LiPos ...

    Well, I recently bought a tb48 which had same problem, returned to retailer and got a new replacement which was doa, no lights and would not charge. Both batteries were brand new in unopened boxes. Contacted seller and informed now to go through dji, now awaiting dji response for over a week. My luck, seller was CopterShop, which is going out of business…

    Just pop the lid if the battery, disconnect the only connector you see, leave for a minute or 2 then reconnect and pop the lid back on. Worked for me. Working fine ever since

    Thanks! I would've expected to be sealed like a proper LiPo.. is this related to the fact that the electronics cannot be rebooted from the outside?

    Did the same as Irish and worked like a charm.
