SHENZHEN, China, Nov. 13, 2025-- As humanoid robots transition from factory prototypes to real-world deployment, breakthroughs in power technology have become the key force driving their evolution. This week, BAK Battery unveiled its new RoPower Series—a next-generation energy solution built to meet the surging demands of advanced robotics.

With the global humanoid robot market, as projected by Goldman Sachs, expected to reach $38 billion by 2035—and potentially exceed $200 billion under optimistic forecasts—industries worldwide are quickly shifting from “automation as an option” to “robotics as a necessity.” Arriving at this pivotal moment, the RoPower Series delivers higher energy density, faster charging, and enhanced durability—empowering smarter, longer-lasting, and more capable robots.

At the same time, a crucial challenge has emerged: power. Smarter AI, more complex sensor systems, and extended operational times are placing unprecedented demands on a robot’s core—its energy system. Against this backdrop, BAK Battery introduces the RoPower Series, offering a more powerful and dependable kinetic energy solution tailored for the robotics industry.

Customized Power for Growing Demands

RoPower18650-30D: High-Intensity Performance

Engineered for outdoor operations and high-intensity logistics, this cell delivers instant power when it counts most. Featuring a tabless design, it cuts internal resistance by 70% to under 5mΩ, boosts discharge capability by 100%, and reduces temperature rise by 30%. With an ultra-high discharge rate of 50A, it supports dynamic actions such as climbing and jumping without delay. Recharge from 10% to 80% in just 9 minutes—blending high power and rapid recharge for maximum operational uptime.

RoPower21700-65E: Extended Endurance

Designed for prolonged tasks like patrols and home assistance, this model extends runtime by up to 30%, supported by a volumetric energy density of 928Wh/L and gravimetric density of 315Wh/kg. Its low internal resistance (<8mΩ) and 4C discharge rate ensure consistent output, while a broad operating temperature range (-30°C to 60°C) and 12 safety certifications guarantee reliability even in challenging environments.

RoPower4695-330B: Uncompromised Safety Under Extreme Conditions

Built for harsh and unpredictable settings, this cell combines high energy density (280Wh/kg) with an ultra-long cycle life of 2,000 charges. A 15-minute fast recharge reduces downtime significantly. Safety is reinforced through tabless technology, keeping internal resistance below 0.8mΩ to prevent overheating, along with multi-level safeguards including zero thermal spread.

BAK Battery has developed a versatile product portfolio—fine-tuning power output, capacity, and safety to align with diverse operational needs. Whether for lightweight service applications or heavy-duty industrial tasks, there’s a RoPower solution ready to deliver.

Liu Zhibo, Executive Vice President of BAK Battery, commented, “Every gain of 1Wh/kg in energy density or 0.1C in charging speed doesn’t just improve performance—it opens up entirely new possibilities. At BAK, we are dedicated to understanding the evolving needs of the robotics sector and expanding our battery family to enable scalable, real-world applications. We’re not just powering robots—we’re energizing global industrial progress.”

The RoPower Series is designed to serve as the “core power engine” for robots—going far beyond simply filling the “tank.” By increasing cell energy density, it doubles operational runtime; through extreme power output, it provides robust dynamic force; and with over 2,000 life cycles, it enables scalable deployment. These innovations not only push application boundaries—they unlock creative potential, accelerating the robotics industry into a new era.
