product performance advantages

Lead-Acid Battery

Utilizing 100% high-purity primary lead (as used in premium "black gold" batteries) ensures significantly higher stability than recycled lead alternatives. Beginning in 2024, the adoption of green hexagonal alloy plates will further improve energy conversion efficiency and power output.

 

Lithium Battery

Offering 50% more capacity than lead-acid batteries of equivalent size, this lithium solution delivers up to 2000 cycles and a service life exceeding 3 years. It has passed rigorous safety tests—including nail penetration and overcharge tests—and incorporates 9 key protection mechanisms to ensure complete travel safety.

 

Low-Temperature Performance

Based on real-world testing during the 2025 northern winter, select models retain over 70% of their room-temperature capacity even at -20°C. With a 30% improvement in low-temperature discharge performance, these batteries effectively mitigate the winter range loss commonly experienced by users in cold regions.

 

Production Advantage

Quality stability

Ensure the quality stability of mass production and guarantee product consistency

 

Product uniformity

Ensure the uniformity of products within the same batch and enhance user experience

 

system stability

Ensure the stability and reliability of the system, and reduce the risk of use

 

Precautions for Use

please read the manual carefully before using it to ensure properly use.

  • Do not make the battery exposure or thrown into fire.
  • Never reverse charge the battery.
  • Never short circuit the battery.
  • Avoid excessive physical shock or vibration.
  • Do not disassemble or deform the battery.
  • Never allow the battery to get wet or be immersed in water.
  • Do not use different types together.
  • Keep away from children
  • Charge at the appropriate conditions.
  • Never use the faulty charger to charging.
  • Never keep charging more than 24 hours.

 

Other Chmical Rerction

The battery performance will reduce if over time using or unused for a long time due to it’s a reaction of chemical. In addition, the battery life will be shorten or injury or damage itself from electrolyte leakage, heating ignition or explosion for improper handling. It’s necessary to replace battery if unable to charge even with proper way.
