Hi @ all,
I started to harvest some cells out of old laptop batteries to be able to build up a small powerwall.
I will post some more information about that on a separate thread.
But right after the start, I got a cell with a very strange charging curve so that I stopped using this one and wanted to ask you.
As you can see in the attached file, the voltage has dropped several times during charging.
This cell is marked with "LGDB118650".
I am using a SKYRC MC3000 with the following setting:
Charging up to 4.20V @ 1.0A
Resting for 20mins
Discharging down to 3.00V @ 1.0A
Resting for 20mins
Charging up to 4.20V @1.0A
The battery did not get warm but I am a bit afraid that a cell could catch fire.
