Frequently Asked Questions (FAQ)

Q1: What parameters and features can be customized in a battery pack project?

A: We offer full-spectrum customization including capacity, voltage (12V–72V+), dimensions, enclosure materials (Sheet metal, ABS, Aluminum), smart BMS communication protocols (CANbus, RS485, Bluetooth), connector types, custom branding (laser etching logo), and UN-certified packaging.

Q2: What is your MOQ and sample lead time for custom battery prototyping?

A: MOQ depends on the customization complexity and cell type. For custom functional prototypes, our typical lead time is 3–7 business days after the engineering design is finalized and approved.

Q3: Can your custom BMS protocols communicate with our existing inverters or systems?

A: Yes. Our proprietary Smart BMS supports CANbus, RS485, RS232, UART, and Bluetooth. We can pre-program communication protocols to seamlessly match major inverter brands (e.g., Growatt, Deye, Victron, GoodWe) or your proprietary system logic.

Q4: How do you handle non-disclosure agreements (NDA) and custom engineering IP protection?

A: We strictly respect and protect our clients' intellectual property. We are fully prepared to sign a formal Non-Disclosure Agreement (NDA) before reviewing your technical drawings, CAD files, or proprietary specs.

Q5: What shipping and compliance certifications do you provide for custom batteries?

A: All our custom battery packs can be tested and certified to meet global market standards, including UN38.3, MSDS, CE, IEC62133, RoHS, and UL2054. We also provide complete UN-certified hazardous goods packaging for smooth international delivery.
