This is more of just an observation but after a year of use, I’ve had three of eight DJI TB55 batteries fail.
They have all failed in the last month. Two of them failed on the same day.
Here is what I’m seeing in trying to troubleshoot the batteries.
According to DJI, the warranty on these batteries is 6 months or 200 charges, whichever comes first.
There has been nothing unusual in the care and handling of the batteries. They are recharged after each use.
If this trend continues then a reasonable expectation would be to have to replace TB55 batteries approximately once a year, or at least budget for replacement.
