Working on a job yesterday and I had two separate faulty TB50s which took two paired sets out of action out of a total of five pairs (Just about managed running on three pairs). The App reported "Battery Cell Error".
Checked the faulty batteries and it was clear that one cell in each had gone to ~4.34v and a significant voltage difference between the cells.
Since then, I've discharged the faulty batteries to <4% and recharged them, but the fault still exists. I can't fly the batteries becuause GO denies flying on this error, so it's a very slow means of discharging by leaving the i2 running for hours, which I hate doing.
One battery is on 7 charge cycles, the other on 15.
Anyway, I'm really worried about this, as this is two separate TB50s, bought at different times (and countries) and they both failed on the same day.
I'm going to set up a support ticket, but keen to hear of any similar issues, as I couldn't see much on the forums about this.
