PL31-40Ah


Characteristics & Advantages of Sodium-ion Batteries


  1. LOW POWER START STOP

    Sodium-ion batteries can start the vehicle even when it is low on power.

  2. ULTRA-LOW-TEMPERATURE STARTING

    Sodium-ion batteries enable vehicle starting in extreme conditions down to -40℃.

  3. ULTRA-LONG STANDBY MAINTENANCE

    Sodium-ion batteries can be discharged to 0V and still be used after recharging without affecting their service life.

  4. HIGH SAFETY

    Sodium-ion batteries are non-flammable and have better safety performance than lead-acid batteries.

  5. LOW COST

    Sodium is abundant and inexpensive, which helps reduce battery costs.

  6. LONG CYCLE LIFE

    Sodium-ion batteries boast extended cycle life, which can last as long as the car.

  7. ENVIRONMENTALLY FRIENDLY

    Sodium-ion batteries contain no harmful substances and are environmentally friendly, in line with the concept of sustainable development.
