It ensures smooth engine ignition for motorcycles in cold winter or high-altitude cold regions, avoiding starting failure caused by low temperature, and is far superior to conventional batteries in low-temperature adaptability.
With an impressive cycle life of ≥2500 times, this sodium-ion starter battery has a service life 1.5 times longer than ordinary motorcycle lithium batteries. It maintains stable capacity output during repeated charging and discharging, with a capacity retention rate of over 80% after 2500 cycles, no memory effect, and supports random charging, greatly reducing the frequency of battery replacement for users.
Adopting sodium-ion chemistry with inherent thermal stability, this 72V motorcycle starter battery has no risk of thermal runaway or explosion, even in high-temperature (60℃) or vibration environments. It contains no rare metals, is environmentally friendly and easy to recycle, complying with international environmental standards. Built-in overcharge, over-discharge and short-circuit protection, it further ensures safe use for riders and vehicles.
This high-performance sodium battery supports 3C fast charging, enabling it to charge from 0% to 80% in just 40 minutes, matching the fast energy replenishment needs of modern electric motorcycle users. It has low internal resistance (≤50mΩ), minimizing energy loss during charging and discharging, with high energy conversion efficiency, ensuring longer riding mileage per charge.
With a lightweight casing (30% lighter than lead-acid batteries of the same capacity), this 72V Na-ion battery reduces the overall load of the motorcycle, improving riding flexibility and energy efficiency. It is fully compatible with mainstream 72V electric motorcycle power systems and starter interfaces, requiring no vehicle modification, and can directly replace traditional 72V lithium or lead-acid starter batteries, with plug-and-play convenience.

Product Uses |
This 72V sodium-ion motorcycle battery is the core starter power source for medium and large electric motorcycles, providing stable cranking current for engine ignition and continuous power for riding. Its 72V voltage perfectly matches the power system of high-performance electric motorcycles, and the fast charging function supports long-distance travel, making it suitable for urban commuting, suburban leisure riding and motorcycle touring.
For motorcycles and snowmobiles operating in cold regions (such as northern winter or high-altitude areas), this sodium-ion starter battery delivers reliable power support. Its -30℃ low-temperature starting performance ensures no starting failure in freezing weather, and the IP54 protection grade resists snow and ice erosion, perfectly adapting to the harsh working environment of cold-region vehicles.
This 72V motorcycle starter battery is also suitable for 72V heavy-duty electric scooters and three-wheeled rickshaws, providing stable starting power and auxiliary riding energy. It can bear the heavy load of passengers and goods, maintain smooth power output during long-time operation, and the lightweight design does not affect the vehicle's load capacity, meeting the daily use needs of urban logistics and passenger transport vehicles.
As a high-quality replacement battery for old 72V motorcycle batteries (lithium or lead-acid), this high-performance sodium battery has better low-temperature performance, longer life and higher safety. It can directly replace the original battery without modifying the motorcycle's circuit or battery compartment, helping users upgrade their vehicle's power system at low cost and improve riding experience.
Product Operate Guide |
Install the battery into the motorcycle's dedicated battery compartment, ensure firm fixation and correct positive/negative pole wiring (avoid reverse connection). Use a 72V sodium-ion dedicated charger (supporting 3C fast charging) for charging, and charge in a well-ventilated environment. Avoid overcharging (do not exceed 84V) and over-discharging (do not lower than 56V). Regularly check the battery casing for damage and terminal connection status, and clean surface dust to maintain good heat dissipation.
FAQ |
Unlike traditional chemistries, our sodium-ion cells possess an ultra-low self-discharge rate of ≤2% per month. Furthermore, they can be safely discharged to 0V for transportation or long-term storage without causing irreversible damage to the internal crystalline structure, allowing for up to 12 months of maintenance-free stocking without capacity loss.
No, the 100A peak is a capacity threshold, meaning the battery can supply up to 100A only if the starter motor demands it. It acts as a robust energy reservoir that effortlessly handles the instantaneous draw of heavy-duty ignitions without causing voltage drops, perfectly complementing and protecting standard 72V wiring harnesses.
Absolutely zero modifications are required. The battery is engineered with a standardized 380×180×220mm footprint and universal terminal placements. It is a true drop-in replacement that instantly upgrades the vehicle's performance, sheds significant weight, and connects directly to existing interfaces.
The IP54 rating signifies that the high-strength engineering plastic casing is highly protected against dust ingress and resistant to water splashes from any direction. In practical terms, this ensures the internal BMS and cell connections remain secure and uncorroded even when vehicles are operated in heavy rain, mud, or dusty industrial environments.
While the voltage parameters are similar, we strongly advise using a dedicated 72V sodium-ion charger that supports 3C fast charging. Traditional chargers lack the specific algorithmic charging curves required to optimize the sodium-ion cells, which could lead to incomplete charges and prevent you from fully utilizing the impressive 40-minute fast-charge capability.
