CBAK Energy Technology Reports Cumulative Sales To A European RV Energy Storage Customer Of ~$4.76M

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.
