Kind of hard to see even with the image resized. Looks like crash damage and not puffed from abuse ?? Is there a hole in the silver cell covering ??
Yes = trash it ..
No = charge it carefully watching for any excess heat that may indicate an internal short

Good Luck

yeah there is a small hole in the lining.. The pack isn't that old .. I may pull that one cell out of it..need more info..
phil

thats a tough one. Best bet it to take that cell out and trash it. Or, charge it in lipo sack and see what happens, and expect the worst.

I have read about guys that have resealed a small hole in a lipo with tape/glue... anything airtight... and they claim it worked fine. I don't know what happened long term with them.

Mabye they died in a mysterious house fire a few weeks later, lol.Ok not funny.

I would do two things.

1. Call Austin and see what he may do to help.
2. Seal the damage and see what happens... keeping a suspicious eye on it at all times.

have you cheked the voltage?

no I haven't checked anything... just saw it yesterday. ran last a few days earlier.. I emailed austin..
phil

Check the cells voltage.

shows 4v right now! why ask about the volts?
phil

Damaged cells might differ in voltage from the rest of the cells in the pack; this would keep me from using that cell.

I would see about getting it out of the pack and use the other cells.

I puffed up a 3s2p 4200 pack recently and salvaged a 4s1p 2100 pack from it to use in an electric ducted fan Jet.Used a heat gun to heat up the pack enough to soften the glue and carefully pried them apart.Added balance taps while I was at it.
hope this helps

well I emailed austin and he said to just buy a new cell and put back in the pack with reg solder sound right?looks like around 20.00 for a new cell.
phil

4v is pritty low for lipo?

If you havent ran the pack over 10 times maybe even a little more im sure it should be fine. Or send it to Austin and tell him to replace the cell, if it is any trouble for you.
