product performance advantages
lead-acid battery
Using 100% high-purity primary lead-acid batteries (such as black gold batteries) ensures superior stability compared to recycled lead products. Starting from 2024, the application of green hexagonal alloy plates will enhance energy conversion efficiency and power output
lithium battery
Compared to lead-acid batteries of the same volume, its capacity is effectively increased by 50%, with a cycle life of up to 2000 times and a service life of over 3 years. The product has passed various extreme safety tests such as needle puncture and overcharging, and features 9 major safety protection mechanisms to ensure travel safety.
low-temperature performance
The actual measurements in the winter of 2025 in the north showed that some models can still maintain more than 70% of their normal temperature battery capacity in a -20°C environment, with a low-temperature discharge performance improvement of about 30%, addressing the pain point of reduced range for users in the north during winter.
production advantage
Quality Stability
Guarantees consistent mass production quality and reliable product performance across all units.
Product Uniformity
Ensures batch-to-batch consistency for a seamless and superior user experience.
System Stability
Delivers reliable system operation while minimizing potential usage risks.
Precautions for Use
please read the manual carefully before using it to ensure properly use.
Other Chemical Reaction
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.
