Systematically I have the message OVER VOLTAGE with a battery TB55, the previous importer has abandoned the import in my country, I wrote the support DJI by presenting all the requested documents and today I am asked to send to my cool battery in the Netherlands, this battery has just 4 months and less than 10 refills, simply unacceptable for an emergency service like ours ...

Hey Olivier, sorry for the troubles. We've checked your video and regretful to tell you this can not be fixed remotely. The new package can be resent to you after the local team received the old one, please kindly arrange at your earliest convenience.

yeah, happened to me as well on apr18, 2 days ago. tb55, left in the dji charger, it beeped when fully charged. i took them off the grid and one of the 2 in the pair kept blinking the overcharge pattern. was ok next morning. will monitor before and during next uav flight (tomorrow). the battery has no more thatn 8 power cycles on it, not dropped or damaged. bought new in november.

at home even after several reloads the problem was still there, a reseller (Optimum system) replaced me under warranty. You should know that these batteries are considered hazardous materials and that DHL do not take them and that Fedex requires that we have a hazardous materials account, without the help of the dealer I discarded and cried my purchase ... Dji dismal service on this one ...

Hello DJI Susan,

I have to report a failed battery, too. and this one is different from the one which overcharged from a few days ago - a different set from my post above. please see the hyperlink to a new video of a failed battery.

after a full charge the night before, I went to work the next day, inserted the fresh set of batteries and m210 cannot take off. gives battery error on the go4 app. 1 of the 2 paired batteries is dead, 0% while its counterpart is 100%.

i charge it as soon as i can and the dji charger doesnt even recognize it anymore. charger reads it ok for a few seconds then nothing - the lights go around in a circle without charging anything. all in the video attached.

i will be contacting my dji dealer to get this replaced.

and yes, it is dangerous goods - regular people cannot ship this over mail, need special account.

Did you try to refresh the firmware? maybe it will help to re balance batteries?
Or wait for Battery Station for TB 55.....

Many I2 users get same issue with TB 50.... and only firmware upgrade or charging with battery Station saved their batteries.

hello, the firmware did not help ...

Sorry about this. I'd suggest sending the unit in as well. The local team will take care once it arrived.
