How to Choose the Right Sodium-Ion Battery for Cars?

When choosing a sodium-ion battery for your car, don’t just compare price or appearance. The most important part is the cell material inside.

For automotive use, you should check:

✅ What cell material is used?
✅ What is the fully charged voltage?
✅ Is it suitable for high-current starting?
✅ Can it replace lead-acid batteries properly?

J-craft Motorsport uses:

Layered Oxide provides better voltage performance and is more suitable for high-rate discharge, especially for car starting applications.

Some Polyanionic sodium-ion batteries are only around 13.3V when fully charged. In our opinion, this makes them less suitable for replacing lead-acid batteries in cars.

J-craft Motorsport clearly states the use of Layered Oxide so customers can understand the difference before buying.

If you need a sodium-ion battery for automotive starting, choose one that is built for high current, not just long-term storage.
