I decided to do a deep discharge with myTB50s, but now I get a solid red light on my charger instead of the flashing green. Is this normal behaviour and will the charging process begin after a while? Or is there a special process to get the batteries to start charging?

Thanks.

Hi Jerry, solid error means battery error, when you plug the battery into the aircraft, is there any error message in the APP? The new firmware has optimized the cell voltage balance, are you running the latest firmware?

Hi Mindy,

This happened with three batteries after updating the firmware. The aircraft will not power up with these batteries as they are fully discharged. However, when I press the batteries’ status button I get a single flashing white LED. They have all done fewer than twenty charging cycles.

Jerry, I'm afraid the batteries have been over-discharged, if the batteries are still in warranty period, please send in for further evaluation.

So these intelligent batteries have no protection to stop them over discharging?  I was closely watching the batteries’ percentages in the GO4 app and none of them showed less than 5% before the aircraft shut down.
