Turnigy lipo repair
So I bought a 5000mah 6s Lipo from hobbyking earlier this year and finally got around to using it. Shortly after setup I ended up with a slight – and I mean slight short in my motor wiring that resulted in a total failure of my motor/controller/batteries. After some testing I found that the battery pack had lost voltage between cells 4 and 5. After pondering the purchase of new batteries I opened up the battery.
This is what I found. I completely separated solder point inside the battery.
A short solder job later and I repaired the point. I added some wire for stability and it passed subsequent tests with motor load and charging.
