Recycling old batteries

I found my 2007 MacBook in the attic and took it apart

I will try to re-use as many components as possible in my future projects, but first I’ll have to learn more about Apple’s components. I started with the battery. In its case are 6 LiPo cells. Unfortunately two of my cells are damaged, but that means 4 are left for further usage. Currently I am trying to charge them with the help of a TP4056 board and a 6V 200 mA solar panel. But to gather more data, I first needed to build a data logger.
