Lithium-ion batteries are clearly leading the way in powering electric bicycles and scooters. Their popularity as the preferred power source for electric mobility tools is due to several technical and safety benefits, which we will examine in detail below.
Higher Energy Density
One of the core appeals of lithium-ion batteries is their exceptional energy density: Compared to other rechargeable battery technologies, lithium-ion batteries can store more kilowatt-hours of energy in a more compact and lightweight package.
This feature directly translates into longer range for electric bikes and scooters after a single charge, so travel is no longer limited by distance.
Efficient Charging
In terms of charging speed, the competitiveness of lithium batteries cannot be underestimated. In most cases, the battery packs of electric bicycles and electric scooters can quickly transition from low power to full power in just 3 to 5 hours , far exceeding the 8 to 12 hours required for traditional lead-acid batteries. Such high charging efficiency greatly shortens the waiting time.
Longer Cycle Life
Under the correct maintenance and use conditions, lithium batteries can withstand more than 500 complete charge and discharge cycles, and their capacity can still remain at more than 80% of the initial state . For daily commuters, a lithium battery is enough to support years of reliable riding, greatly reducing the frequency and cost of battery replacement, and providing users with a more economical and environmentally friendly travel option.
Higher Peak Output
When powered, lithium-ion batteries can quickly reach and maintain high peak power output, which is critical for vehicle performance in high-load scenarios such as acceleration and climbing. This immediate power response ensures that the rider experiences a strong and sensitive acceleration feeling, making the ride smoother.
Voltage Stability
During battery use, the voltage of lithium batteries changes relatively slowly, and even as the battery gradually consumes, it can maintain a relatively stable power output. This feature helps provide a continuous, non-attenuated riding experience and ensures that the electric vehicle can maintain stable performance when the battery is reduced.
Low self-discharge characteristics
Compared with other rechargeable batteries, lithium batteries have a significant advantage of low self-discharge. If not used for 30 days, the power loss can be as low as 1%. This feature is particularly important for electric vehicles that need to be parked or used as standby for a long time, ensuring that the vehicle is always available.
Safety Mechanism
Each lithium battery cell contains independent protection circuits that monitor voltage, current and temperature. They can isolate damaged or faulty cells to prevent a chain reaction.
To avoid overheating during charging or high loads, the lithium battery pack is equipped with temperature sensors, vents and fire-proof enclosures to reduce the possibility of thermal runaway caused by internal short circuits.
Waterproof
The lithium batteries used in OKAI's electric bicycles and electric scooters have reached the IPX5 or higher waterproof standard. This technical specification ensures that the battery has higher protection performance when facing humid environments, splashing water and even light rain.
Compared with lead-acid batteries, which have relatively insufficient sealing, OKAI's lithium batteries can effectively resist moisture intrusion, ensuring the safety of the battery's internal circuits and components, thereby extending the service life of the vehicle.
OKAI insists on choosing high-quality lithium-ion batteries as the core power source of our products. We are well aware that in the pursuit of green, intelligent and safe travel, technological innovation and quality control are two indispensable driving forces.
The lithium-ion batteries used in OKAI's entire product line not only provide ultra-long battery life, fast charging, and stable power, but also serve as a safety guard for every trip with their powerful safety performance and durability.
We are committed to making every product a trusted partner for users, accompanying you through the city or across the mountains, and enjoying the fun of free riding!
