    Low voltage..

    My idiot cousin managed to get one of my 2s lipos down to low voltage, luckily I was able to nimh charge it for around 10 seconds and save it. My question is, is my battery damaged somehow? Is it safe to run with it? Has this happened to you?

    Damaged, yes. To what extent... hard to say. Does it still balance charge to full voltage? If it does, I would use it with extreme caution the first few times and then just keep a closer eye on it for any puffing or irregular behavior.

    I have over discharged a Lithium Ion cell in a project of mine. I was modifying a circuit board and my cheap multimeter did not read the slow draw on the cell so it drained it to around 2 volts overnight. It no longer charges to full voltage and does not last anywhere near as long as it should. I have ordered a replacement.... no puffing due to it being in a metal casing.
    Whatever it is I just said... I could be wrong.

    Charges normal. I'm very mad about this. I paid $60 for this battery.
