Why Partner With Us? (Value & Risk Reduction for B2B Buyers)
Lower Your After-Sales RMA Rate: Rigorous Quality Control
- 100% Cell Matching & Sorting: Every cell undergoes strict grading for internal resistance, voltage, and capacity before assembly. This prevents premature pack degradation caused by cell imbalance.
- Dual Thermal & Insulation Protection: High-grade insulation boards separate cell matrices, wrapped in heavy-duty PVC shrink film to withstand vibration and ambient humidity during daily rides.
Enhanced End-User Satisfaction: Intelligent BMS Integrated
- Built-in industrial-grade BMS prevents overcharging, deep discharging, short circuits, and thermal runaway.
- Smooth discharge curve ensures steady acceleration even at low State-of-Charge (SOC), boosting rider confidence.
Tailored OEM/ODM Flexibility: Stand Out in Your Market
- Dimensional Customization: Flexible cell layout matrix to fit unique frame tubes or under-seat compartments.
- Custom Cabling & Terminals: Tailor-made discharge/charge connectors (XT60, XT90, Anderson, DC) for plug-and-play integration with your motor controller.
- Private Labeling: Custom logo printing, serialized barcodes, and branded packaging for your market identity.
Application Scenarios
- Electric Bicycles (E-Bikes): E-Mountain bikes, city commuters, and heavy-duty cargo bikes.
- Electric Scooters (E-Scooters): Fleet sharing and high-speed personal mobility scooters.
- Specialty Light EV Devices: Delivery tricycles, golf caddies, and small utility vehicles.
Manufacturing & Quality Assurance
We understand the importance of lead-time accuracy and repeatable manufacturing quality for B2B buyers:
- Precision Automated Spot Welding: Ensures low internal resistance and robust mechanical connections across all nickel strips.
- Full-Cycle Aging Tests: 100% of battery packs undergo complete charge-discharge cycling and environmental stress testing before shipment.
- Global Logistics Compliance: Fully certified with UN38.3, MSDS, and Hazardous Goods shipping documentation for seamless customs clearance.
Frequently Asked Questions
Q1: What is the Minimum Order Quantity (MOQ) for bulk orders?
A: We support growing brands. Sample orders are available from 1 unit for evaluation. Bulk pricing is offered on a tiered structure based on volume and customization needs.
Q2: Can you customize the pack size to fit our proprietary battery enclosure?
A: Absolutely. Our engineering team can analyze your CAD drawings or physical enclosure dimensions to propose optimal cell arrangements and BMS layouts.
Q3: What is your warranty policy, and how do you handle technical support?
A: We provide a 12 month warranty depending on cell selection and usage conditions. In the rare event of a quality issue, we offer rapid replacement modules and technical root-cause analysis support.
