  • Surpassing lead-acid batteries with 3,000 charge-discharge cycles, there is also an increase in the number of ignition times.
  • The self-discharge rate is as low as 1.5%, which is beneficial for those who do not ride motorcycles frequently.
  • The fast-charging feature facilitates our travel. It only takes 20 minutes for the battery to reach near full capacity.
  • Excellent low-temperature performance. The vehicle can start normally even under extreme climatic conditions.
  • Thanks to a higher energy density, the weight and volume of the 12V 3.9Ah sodium battery are much less than that of lead-acid batteries.
  • The safety performance is very high and reassuring, as it has passed tests for overcharging, over-discharging, short-circuiting, and puncturing.

In summary, if you are not at ease using lead-acid batteries, or if you are looking for a power source with a better cost-performance ratio, then sodium-ion batteries would be a better choice for you. They can replace various types of lead-acid batteries, providing a continuous source of power for your motorcycle.
