The battery cells are usually working fine. It's the charging board in the battery pack that fails.
All you have to do is bypass the board & the battery charges properly. Refer to the video for the explanation

I purchased a damaged P4 that had been repaired (badly). Had all 4 ESC errors. Multimeter checked for continuity between motor windings on esc connections & all were open circuit. The wires had been cut & connected without solder or removing the varnish from the wires. Nice heatshrink job was...
