Rear shocks overhauled.
I would be a pitty to throw the dead lipo in trash bin.
So I took the lipo apart and charged cell by cell.
Conclusion: cell number 5 is dead so I took the number 5 out.
And made a 5S pack for bashing and my new Hyperion 6S 45C 4200 will be use for speedruns.

Dead cell number 5 cell.
