TB48 imbalance

[rg155]

Hi all,
I recently tried to revive a dead TB48 and had t turned on and the batt dropped from 82 to 0 while hovering. Is there anyway to get the cells to balance?

you can try to drain it completely, then re charge and see. if not then it gets more involved. but yea turn the Inspire on and start the motors, and let it just sit until it dies

It completely died shortly after and gave the overcharge error after a few minutes of charging.

then time to get involved.

POLL: Would you purchase a harness to fix TB-47/8 batteries??

I’m going to try bringing back another one and I’ll see how that works.

good luck. Ive had like 6 dead batts, with a 0 success rate of bring them back and working

When you tried to jump the batteries did they get really hot when you put them on the real charger?

they got really hot while i was jumping them. got them up to the required voltage and held there like 5 mins, then tried to charge normal and nothing. even putting in the bird got nothing

Ok, mine got a little warm towards the end and then I put them in the charger and it got to 63% and it worked and took off then I charged it to 93% and then the issues happened such as the battery error.

Totally get that, I’m not willing to spend almost 700 on batteries though. I would probably never trust them but a fun experiment.

yea inspire can get expensive. Just check eBay for deals

Is there anyway I could open the battery and charge them individually?
