The project is a 48v 24-ish kWh 14s245p powerwall where I'm using harvested 18650 cells with around 2000 mAh. Based on my house's average energy consumption, I'm looking at roughly 215 mA of continuous current per cell. The 48v inverter I plan to get has shut down voltages at 42v (~3.0v per cell/series) and 59v (~4.2v per cell/series). With this info, when testing the capacity of each 18650 cell, what voltage should I charge each cell to and what cutoff voltage and discharge current should I set for each?
