It all started from something small




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 ?

It is a normal thing with cheaper, not well cared Lipo. Fly them but with care.  avoid using high charge or discharge rate.

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.
