If the li-po is swelling when charging at 1c and then you are drawing more than 1c on discharge, and you are.
What is happening to it ? ?
How long will it last before it becomes useless ?
If Li-po's were designed to swell up they would be in a larger case to allow for the swelling.
The one in the picture looks new - there are no scratches in the tubes and judging by the badly sized sticker partly covering the + symbol on the case the sticker cannot be the bit made in the USA. Its probably the fingerprint of the guy unpacking them after shipping from china !
