100 mW
I'm constructing a 20S-10P battery pack for an e-scooter. I have:
- 150 cells of Panasonic NCR21700 5000mAh
- 50 cells of Samsung INR21700-50E 5000mAh
Both sets of cells are supposedly those used in Tesla Model 3s and Ys though I assume each of their battery packs use homogeneous cells.
Should I make each parallel cell group heterogeneous (mix some Samsung cells in), keep each cell group homogeneous (make a couple of the parallel groups entirely Samsung), or avoid this idea all together and try to buy more Panasonic/NCR cells?
