I have 30x 3.2Ah and 18x 3.8Ah 26650 LiFePo4 cells. I plan on making a 4S4P with the 3.8Ah for a 12.8V 15.2Ah battery. That will leave me with 30x 3.2Ah and 2x 3.8Ah cells for another project.
I'm planning on making a 4S7P out of the 3.2Ah cells for a 12.8V 22.4Ah battery. That will leave 2x of the 3.2Ah and 2x of the 3.8Ah.
So, my question is... Can I throw those final 4x cells into my 7P battery to make it an 8P? They are all LiFePo4, and I'm thinking it would de-rate the 3.8Ah capacity to 3.2Ah to match the rest of the battery which I'm fine with since I don't have another project in mind for those cells. It could bump my battery up to 25.6Ah.
I'm not thinking this is a good idea as I am worried about the voltages between the cells being too different at varying state of charges but wanted to check before I left some potential capacity on the table.
Thanks!
