Frequently Asked Questions

Q1: Can NA 210Ah sodium-ion cells operate at -40°C?

Yes. According to the manufacturer's datasheet, the cell retains approximately 65% of its 25°C discharge capacity at -40°C under 0.5C test conditions.

Q2: What is the cycle life of the NA 210Ah cell?

The manufacturer specifies 4,000 cycles to 70% of nominal capacity under defined testing conditions.

Q3: Can I use a standard LiFePO4 BMS?

A standard LiFePO4 BMS should not be assumed compatible. The sodium-ion cell has different voltage limits and requires an appropriately configured BMS and charger.
