Title: LiPo puffed and then not ! Post by: parichya.gautam on February 12, 2015, 12:02:07 PM So i have this zippy 5000mAh LiPo.
the weird issue is that when the LiPo is charged , its all good , like a brick. But when it is discharged , say after a flight , it looks puffed IE: i squeeze it and there is air inside . but when I recharge it , it is fine again .. Is it fine or somethings wrong here ?

Post by: satyagupta on February 12, 2015, 03:30:23 PM So this happens when even if once your any of the battery are over discharged (means below 3.3V) this has happend with me many times. I have many times while flying even after hearing beeps continued flying for 3-5 seconds.
The puffness appears only after flying and later when you charge it would disappear. |
