When do I need to stop using my LiPo?

[Rocking Donkey]

One of my LiPo cells has expanded a little. The hard case has probably expanded only by a mm but there is it is noticeable. Also the LiPo drops straight to 8V after changing. The other identical pack I have has not expanded at all and stays at 8.2V after charging.

I know I will need to replace the pack, but am trying to hold on until the BRCA list comes out. Is it still safe to keep using the pack until then, or do I need to bin it now?

Bin it now if a cell isn't holding it's voltage and you already got a little swelling, it may pop under charging, or worse, in your car.
