Collection: Sodium Cells

Genuine NAIONICS prismatic sodium-ion cells: 3V 75Ah, 3.0V 160Ah with 2C maximum discharge (model CSC-71173208-HP160) and 3V 230Ah, for building leisure, starter and storage packs.

Sodium chemistry sits at about 3V nominal instead of the 3.2V of LiFePO4, so the number of cells in series for a given system voltage changes: more cells to reach the same voltage, and a BMS with the right thresholds for sodium, not the ones for lithium.

In return you get cold tolerance down to -20 °C with no heating, resistance to full discharge and no critical raw materials. Bare cells always need a BMS of their own.
