Battery issue

[Insyder3]

Are there any general rules of thumb to tell me when I have a bad battery. I'm relatively new to drones and just getting into some of the technical aspects of it. Any direct advice would be helpful.

BTW- I'm flying a P3 Advanced.

Thanks.

Blue smoke, lol.

Okay, for real now:
Swollen packs
Cell deviation.
Longer than expected charge times.
Shorter than expected flight times.
Warm to hot during charging.
Warning messages from DJI Go apps.
Last but most important, unexpected power loss or complete shutdown.

And take a look at AIRDATA.COM. It's free and can help track cell deviation.

That makes sense. Thank you.
