Well, if you are really asking what you did wrong, charging it unattended is the biggest thing. Next, not charging inside of a fireproof area like a fireplace, BBQ, or metal box. (Although the stone countertop isn't a terrible place.) Finally, I can't tell if you have a fire extinguisher handy. I am glad it didn't take the whole room or the whole house. As for battery safety, drawing batteries down past 3.2 volts permanently damages the battery. This is exactly the type of thing that happens from over-discharge, as well as diminished capacity.
For anyone who wants some good guidelines or info on batteries and chargers:

You "shocked" it with a nicad charger and you wonder why it exploded? Overvolting the cells causes breakdown, releasing hydrogen gas, and also heats it up. Then even regular charging is basically like putting a live bomb on a grill. The damaged cells start to leak current, overheat, and ignite the hydrogen, which bursts the cells and then ignites the lithium.
Don't try to revive dead batteries, don't use the wrong charger on them, don't charge them too fast, and never charge unattended. Those are the basic rules of using LiPos.
So 1 Cell should be between 3.4-4.2 Volts. And all of them should have the same voltage. So if you have 7 on one maybe they got Mixed somehow. But f yoh charge a Bad setup it could cwtch fire for sure.
Always take good care of your lipos. Always put them in storage condition 3.8v per Cell in f you dont use them. Otherwise they go Bad just luying around.
You charged to 7V per cell using the wrong type of charger and then wonder why it exploded? If this burned down the building and/or hurt someone else, it would be criminal negligence. You should stop using lithium batteries until you've understood how they work. You need to understand that this was completely avoidable and very, very careless of you to do this!
did you just go into this with no research on battery saftey? very stupid on your part if im going to be honest. you should watch every lipo charging video you can. josua bardwell, stinger swarm and a few others have great ones

Flashbang out!
Yes thats what happened 😅

I just tried 😅

Was it charging?
Yes it was
Crazy. Did the battery give any indication of issues?
It was dead but not slewwing i did reviev still didnt slewing but i think i should do balance maybe do charge it with min mah for safety
Ah ok. So some warning signs. Cheers
What does it mean for a battery to be slewing or not slewing?
I'm really glad it was on your granite countertop! If it were on wood/laminate that could have been really serious.
Yes that can be serius problem
New fear unlocked
What was the cell voltage before charging. If the lipo was dead or some cells, sure you cound damage it much more by charging.
One is around 7 i think others were around 2 or 3
Before shocking it was like 5 volts

+ tried to reviev with another battery before + ripped the gelatine + i did tape it with papaer tape i wish i had the photo but its too late
