Chinese firm unveils more reliable, efficient battery

With the formal implementation of the new national standards, GB43854-2024 Safety Technical Specification of Lithium-ion Battery for Electric Bicycle and GB40559-2024 Lithium-ion Cells and Batteries Used in Electric Self-Balancing Vehicle and Scooters — Safety Technical Specification, the electric two-wheeled vehicle market is advancing toward greater standardization and regulation.

In response to these developments, BAK Battery has officially launched the PRO-M High-Safety Battery, which not only complies with the new standards but also delivers dual upgrades in safety and performance, providing a more reliable and efficient energy solution for short-distance travel.

For instance, BAK said its PRO-M High-Safety Battery could pass the industry's most stringent nail penetration tests, ensuring compliance with the safety and performance requirements of the new national standards.

As the electric two-wheeled vehicle market trends toward higher-end, personalized, and intelligent designs, consumer demand for mid-to-high-end products and high-performance batteries continues to rise. The PRO-M 18650 High-Safety Battery boasts a capacity of 2.0Ah, an energy density of 170Wh/Kg, and supports 5C continuous discharge.

Meanwhile, the same series' 21700 battery offers a capacity of 3.0Ah, an energy density of 180Wh/Kg, and supports 4C continuous discharge. Both batteries exhibit exceptional performance with a wide temperature range and long cycle life, capable of stable discharge between -30 C and 70 C, with a cycle life exceeding 1,000 cycles.

Looking ahead, the battery manufacturer said it plans to leverage its innovative capabilities to expand the applications of its cylindrical battery portfolio into broader safety-related sectors, including emergency security and specialized equipment.
