Questions & Answers
What information should I send for a custom battery?
Include the application, nominal voltage, capacity or energy requirement, continuous and peak current, installation dimensions, connectors and communication protocol. A drawing and controller or inverter specification are helpful.
How do I choose between LiFePO4 and ternary lithium-ion?
Start with the application requirements: available space, weight, operating voltage, load profile and operating conditions. Our engineering team can review the suitable battery platform for your project.
Can a battery communicate with my inverter or controller?
Compatibility depends on the exact equipment model and communication protocol. A CAN or RS485 interface alone does not establish compatibility. Send the model and interface documentation for review.
Can I request a different voltage or capacity?
Yes. Submit the required parameters through the technical support page. Engineering will review cell configuration, BMS requirements and installation constraints before confirming a solution.
Where can I request certificates or test documentation?
Use the Certification page as the documentation hub, or contact us with the battery model and destination market. Availability and applicability must be checked for the specific configuration.
What should I include in a technical issue report?
Provide the model or serial number, the connected charger or equipment, observed symptoms, operating conditions and any BMS alarm information. Include clear photos or relevant technical documents where available.
What are the warranty and return conditions?
Detailed terms have not yet been published on this page. Please request the applicable written warranty and service terms for your product or order from our support team.
