Custom Utility Vehicle Battery Pack
Heavy-duty utility vehicles require robust, vibration-resistant power sources designed to replace traditional lead-acid systems without chassis modifications. This Custom Utility Vehicle Battery Pack utilizes automotive-grade or high-power cylindrical and prismatic LiFePO4 cells, tailored to match specific operating voltage platforms (24V, 36V, 48V, 72V, or 80V).
Engineered with in-house pack architecture, laser-welded busbars, and custom sheet metal enclosures, each unit delivers stable discharge under high continuous loads, maintains reliable ingress protection, and integrates seamlessly via standard CANbus protocols with existing vehicle controllers.
Manufacturing Verification: Production lines utilize automated laser-welded copper-nickel busbars coupled with real-time CCD optical weld inspection, ensuring minimal electrical resistance and eliminating inter-cell connection failures under severe off-road vibration profiles.
Key Features
High C-Rate Performance: Sustained continuous high-current delivery for steep inclines and heavy payload towing without excessive voltage sag.
Smart BMS Protection: Real-time monitoring of individual cell voltages, pack temperature, and system current; features hardware-level short-circuit, overcharge, and deep-discharge protection.
Extended Cycle Life: Delivers 3,500 to 5,000 cycles at 80% Depth of Discharge (DoD) at room temperature, substantially lowering total cost of ownership compared to lead-acid batteries.
Fast Charging Capability: Supports 1C fast-charging protocols to minimize vehicle downtime during multi-shift operations.
Rugged Mechanical Construction: Internal shock-absorbing dampeners and epoxy-coated busbars withstand continuous off-road mechanical shock and vibration profiles.

Customization Options
We engineer power packs around your vehicle's physical and electrical envelope:
Mechanical Dimensions: Custom casing sizes, mounting bracket layouts, and center-of-gravity optimizations to fit existing battery compartments.
Electrical Architecture: Series/parallel cell configurations designed to meet exact voltage and run-time targets.
BMS & Software: Custom CANbus ID mapping, integration with specific motor controllers (e.g., Curtis, Sevcon), and tailored dashboard telemetry outputs.
Thermal Management: Integration of low-temperature heating films for sub-zero environments or liquid/air cooling channels for continuous high-load applications.
Quality Control & Testing
Manufacturing and verification take place in-house to ensure lot consistency:
Cell Sorting: Internal Resistance (IR) and capacity matching within a 1% variance prior to pack assembly.
Welding Inspection: CCD optical inspection applied to automated laser-welded nickel/copper busbars.
Electrical & Functional Testing: 100% full-load aging tests, BMS calibration, and high-voltage insulation dielectric strength testing (2000V DC).
Environmental & Safety Compliance: Units undergo vibration table testing (simulating rough terrain transport) and thermal chamber cycling.
Traceability & Documentation: Each pack ships with a unique laser-etched serial number, individual test report, Material Safety Data Sheet (MSDS), and UN38.3 test summary.
Packaging & Shipping
Packaging: Secured in UN-certified heavy-duty wooden crates with high-density anti-static foam blocking to prevent shifting during transit.
State of Charge (SoC): Shipped at an optimized 30% SoC in strict compliance with international maritime and air transport safety regulations.
Documentation Support: Provision of complete Dangerous Goods (DG) declaration paperwork, UN38.3 test summaries, and commercial customs documentation for seamless global delivery.
FAQ
Q: Can this pack directly replace an existing 48V lead-acid setup in our utility vehicle?
A: Yes. Physical dimensions, terminal layouts, and discharge curves are custom-engineered to drop directly into the existing battery well without modifying the vehicle frame.
Q: What communication protocols are supported by the BMS?
A: The standard BMS supports CAN 2.0B and RS485. The communication matrix is adaptable to match your specific motor controller or instrument cluster requirements.
Q: What is the typical lead time for custom prototype samples?
A: Standard electrical and mechanical design verification takes 3 to 5 days, with prototype sample assembly and testing completed within 3 to 4 weeks.
Q: How do you handle cold-weather operation for outdoor utility vehicles?
A: Optional internal low-temperature heating elements, managed automatically by the BMS, are available to enable safe charging when ambient temperatures drop below freezing (0°C).
Q: What certifications accompany your battery packs?
A: Cells and complete packs are manufactured in facilities complying with ISO 9001 standards. Pack designs are tested to meet UN38.3, CE, and RoHS requirements, with UL-compliant component sourcing available upon request.
Q: What is the Minimum Order Quantity (MOQ) for custom enclosure designs?
A: For custom sheet-metal tooling and enclosure sizes, flexible low-volume batches are available for pilot vehicle fleets, supported by scalable pricing tiers for serial production.
