Best 18650 Cells for DIY Powerwalls
A powerwall is a stationary storage pack charged from solar or the grid and discharged slowly to run household loads. Discharge current is low, so capacity is what matters. More mAh per cell means more kWh per pack. These 18650 cells have the highest capacity for powerwall-friendly builds. We filtered for cells with at least 2500mAh.
