DALIAN, China, Oct. 14, 2026 (GLOBE NEWSWIRE) — CBAK Energy Technology Limited (NASDAQ: CBAT) (“CBAK Energy” or the “Company”), a China-based lithium-ion battery manufacturer and energy solutions provider, today reported approximately US$4.76 million in cumulative sales to a European recreational vehicle (“RV”) energy storage company. The relationship began with cell samples supplied for evaluation in 2023 and expanded into a broader commercial collaboration in 2025. CBAK Energy supplies cylindrical lithium iron phosphate (“LFP”) cells and provides engineering support for the customer’s RV original equipment manufacturer (“OEM”) and aftermarket applications.
RV Energy Storage Requirements
RV battery systems face road vibration, temperature fluctuations, intermittent solar charging and frequent charge-discharge cycles. Air conditioners and induction cooktops can draw substantial power, with air conditioner startup placing additional demands on the battery system. These conditions and limited onboard space make cell performance and system integration important considerations in RV battery design.
Cell Options for RV Battery Systems
For RV systems requiring sustained power and frequent cycling, CBAK Energy’s 26650 FS4 full-tab cylindrical LFP cell supports 3C continuous discharge and 1.5C charging, with a cycle life of more than 3,000 cycles under specified 0.5C test conditions. It also supports discharge at -20°C. These characteristics are intended to support high-power onboard appliances and frequent charging and discharging. The customer has set an 8–10-year service-life design target for its RV battery systems, with actual service life dependent on usage and system design.
The Company also offers its 32140FS large cylindrical LFP cell for RV battery systems where power, size and weight are key design considerations. The cell supports 2C charging and 3C continuous discharge, with a cell-level energy density of 165 Wh/kg and a cycle life of at least 2,500 cycles under specified test conditions.
Engineering Support for RV Battery Systems
CBAK Energy works with the customer on battery management system (“BMS”) integration, prototype validation, simulations of operating conditions and reliability testing. Evaluating cell and system performance under high-current loads, at low temperatures and in off-grid use helps identify potential issues earlier and refine system designs.
This work supports the customer’s efforts to serve leading European RV manufacturers and expand in mobile energy storage. CBAK Energy also provides relevant UN 38.3 test documentation, applicable IEC documentation, safety data sheets and transport documents to support product qualification and shipment preparation for European and other overseas markets.
“This collaboration demonstrates the commercial value of combining LFP cell supply with engineering support,” said Zhiguang Hu, Chief Executive Officer of CBAK Energy. “RV applications place demanding requirements on battery performance, reliability and integration. Working closely with this customer gives us practical insight to guide product development. We plan to use what we learn from these partnerships to develop our cylindrical LFP products and grow our business in other mobile and off-grid energy storage markets.”

Forward-Looking Statements
This press release contains forward-looking statements within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. These statements include expectations regarding the continued development of the Company’s collaboration with its European RV energy storage customer; customer testing, qualification and commercial deployment of battery systems incorporating the Company’s cells in RV OEM and aftermarket applications; the customer’s 8–10-year battery system service-life design target; the suitability and expected performance of the Company’s cylindrical LFP cells in RV applications; the potential benefits of system integration support, prototype validation and reliability testing; future product development; and the Company’s plans to expand its mobile and off-grid energy storage business and international market presence.
Words such as “expect,” “estimate,” “anticipate,” “believe,” “intend,” “plan,” “target,” “may,” “will,” “would” and “could,” and similar expressions, identify forward-looking statements. These statements are based on current expectations and assumptions and involve risks and uncertainties that could cause actual results to differ materially.
Risks include changes in customer demand, product requirements and market conditions; the timing and outcome of customer testing, system validation and qualification; whether these activities lead to commercial deployment or additional orders; differences between cell-level test results and actual battery system performance; the ability of battery systems to achieve intended service-life targets under varying operating conditions; battery pack design and BMS integration; manufacturing yields, product quality and supply availability; regulatory, certification and transportation requirements; competing battery technologies; and other risks described in the Company’s reports filed with or furnished to the U.S. Securities and Exchange Commission.
The cell performance figures described in this release relate to specified test conditions and should not be interpreted as guarantees of battery pack or vehicle performance. The 8–10-year battery system service life is a customer design target, not a demonstrated operating lifetime. Actual system performance and service life will depend on battery pack design, BMS strategy, charging and discharging patterns, environmental conditions, usage and other factors.
Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release. Except as required by applicable law, the Company undertakes no obligation to update or revise any forward-looking statements as a result of new information, future events or otherwise.
