FAQ

Q1: Can the Na 210Ah Sodium-Ion Battery discharge at -40°C?

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

Q2: What is the nominal energy of one cell?

Each cell has a nominal voltage of 3.1V and a capacity of 210Ah, providing approximately 651Wh of nominal energy.

Q3: How many cycles does this sodium-ion battery support?

The manufacturer specifies 4000 cycles to 70% of nominal capacity under defined test conditions.

Q4: Can I use a standard LiFePO4 BMS and charger?

Do not assume compatibility. Sodium-ion cells have different voltage requirements. Use a BMS and charger specifically configured for the cell's operating limits.

Q5: Where will my order ship from?

The Na 210Ah Sodium-Ion Battery Cells are available from our Poland warehouse for European customers. Shipping options and delivery times depend on the destination and order quantity.
