Don't touch it and keep it in an ammo box outside. It could catch fire (basically exploding) at any time.

That's not the case I was referring... If you charge a pack in a cool air conditioned house at around 70°F, the cells will increase voltage past 4.20V per cell if you take them outside into extreme heat, like the trunk of a car which can easily go past 140°F and cause the cells to swell/puff with both a combination of intense heat and over voltage

THE OP HAD DONE NONE OF THIS IT WAS PUT IN LONG TERM STORAGE IN HIS BASEMENT.

They can do this if you don't put them at a safe storage voltage first.

not to knock smc because I have spent a lot money on motors/esc/batteries. I am just saying what happen to me, I know it could happen to any brand. but I have had 3 smc batteries go bad in last couple seasons, all were never ran below 3.6 always put in storage and cycled over winter. I e mailed Danny and was told that they just aren't making batteries like they used to and basically shouldn't expect to get more than a season out of a lipo....

I guess it still have that explosive punch.

which is why I gave an example of what I fear the OP may have done something similar

Did he leave the battery fully charged?
What were the temps in the basement?

These are variables to consider that I question and provided an extreme example with storing packs in the truck of a car for a relatively short period of time

Never used is never charged ..

Thanks for the input. Storage is temperature controlled unit. I may have tried to charge once I got it. Didn't remember exactly. I just want to prevent not happen again. My other batteries are fine. I'll try to find a way to dispose safe. Much appreciated.

FYI, saltwater baths only work if the solution can enter the interior of the cells to neutralize them. Submerging the cells in the saltwater will do very little in the way of actually discharging the pack, the thin aluminum tabs on the cells will corrode away long before the pack is discharged.

The safest way to discharge that pack is to set it on concrete, inside of a concrete block, and discharge it using either the NiMH discharge setting on your multicharger or using automotive lightbulbs. Once that pack is good and dead, short the main leads to prevent it from recovering any voltage, then wrap it up in duct tape and toss it. It's harmless at that point.

so this was total user error..knowing a batteries condition is a must when using a lipo.
