Low LiPo Cell

This is my first time to play FPV, there is a problem about Lipo battery. I only have a couple 3s LiPo batteries for my quadcopter. I broke them in when I got them, charging and discharging at 1c. Problem is, one of my batteries has a cell that, when the others drop to 3.7v while flying, the drops to 1.5v and my drone falls out of the sky. It charges and balances correctly, and I'm wondering if there is any other way to fix the cell other than replacing it completely, or is the battery dead.

Hey Diven..........I don't have the most experience with lipo batteries in quads, I had some experience using them in vape mods. When a lipo starts misbehaving, I get rid of it. For me the consequences are just to serious to mess with 'em...........

Sound like you bust a cell. Did you crash. You can't fix a single cell. The battery is dead, RIP. buy a new one. Not the same make. Turnigy are reliable battery's.

You could replace just that cell, but then it is never going to balance with the other two being the lower ones as the whole battery was damaged, one cell just took the brunt of that damage. Sorry to say but sometimes you just have to replace them.

What type of power are you using? A lot of people like the TUrnigy Graphene and I have a collection of the Tattu 45c, 75c, and R-Line batteries. They do great for quadcopters, popular for racing too.
