7 volts in a 3 cell lipo, how dumb am I?
 
Does that mean I have 2 and a 1/3 volt per cell? :lmao::oops::lmao::cry::cry:

Am I that dumb? :flipoff:

Thanks.

Be sure to get it on film so we can all see it. "thumbsup"

The battery only has 1 cycle on it and has been below threshold for under 10 hours. It is currently on a trickle charge, outside on concrete away from anything. I am sitting here on my laptop waiting to swap it onto the good ol thunder power.

As I understand it I have a low chance of some sort of permanent damage which would result in ballooning given the short period of time the battery has been undercharged.

FWIW I do have a fire extinguisher ready 8)

It just started to balloon slightly in one of the cells. Oh well, to the trash with it.

Be sure to properly discharge it before you do that.

I think to properly discharge for disposal you put the battery in a bucket of saline. (salt water) for like 24 hours.

Take it behind the shed out back and shoot it, it's how I put down all good things that stopped working.....

I have read to soak it in salt water from as little as 12 hours to as much as 2 weeks. But I have also read the salt water occasionally causes the contacts to corrode and the battery will remain with an unknown charge (and even worse may read 0 volts while still containing a dangerous charge). A light bulb seems like a fail safe way to discharge the battery safely.
