Custom & OEM Battery Pack Engineering

Your Application. Our Engineering. A Perfect Power Match.

Off-the-shelf battery packs rarely fit the exact dimensions, voltage requirements, or communication protocols of your specific product. At PowerPackHub, we specialize in turning your technical requirements into fully validated, compliant, and production-ready battery packs.

Whether you need a single prototype for a university research project or 10,000 units for a commercial fleet, we engineer power solutions that fit your exact specifications—no compromises.

🛠️ What We Can Customize

We don't just assemble cells; we engineer the entire pack architecture. Our customization capabilities include:

  • Chemistry Selection: NMC (High energy density), LiFePO4 (Maximum safety & cycle life), or Ni-MH/Ni-CD (Extreme abuse tolerance).

  • Voltage & Capacity: From 3.7V to 72V+ and up to 300Ah+ configurations. (1S to 20S+).

  • Form Factor & Enclosure: Custom hard plastic cases, aluminum shells, or heavy-duty heat-shrink wraps to fit tight spaces.

  • BMS & Smart Communication: Custom BMS parameters, CAN bus / RS485 communication, state-of-charge (SOC) indicators, and low-temperature cut-offs.

  • Connectors & Wiring: XT60, XT90, Anderson, Molex, or custom waterproof connectors with specific wire lengths and gauges.

  • Certification & Compliance: Built to meet UL, CE, UN38.3, and IEC62133 standards. (Class 9 Dangerous Goods compliant).

🚀 Our 4-Step Custom Engineering Process

We take the guesswork out of custom manufacturing. Here is how we bring your battery pack to life:

  1. Consultation & Spec Review: Send us your requirements (voltage, capacity, dimensions, max continuous discharge, and application). Our engineers will review your specs and recommend the most cost-effective chemistry and BMS solution.

  2. Design & Prototyping: We provide a 3D CAD drawing of the pack layout. Once approved, we build a physical prototype for your testing.

  3. Validation & Testing: The prototype undergoes rigorous testing (capacity verification, high-load discharge, thermal performance, and BMS logic) before final approval.

  4. Mass Production & Delivery: Once the prototype is locked, we move to mass production with 100% quality inspection. We handle the Class 9 dangerous goods shipping paperwork and deliver directly to your facility.

💡 Why Partner with PowerPackHub?

  • US-Based Support & Returns: We are not a faceless overseas factory. With a dedicated processing and return facility in Rancho Cucamonga, California, we provide localized support, faster replacements, and peace of mind for North American businesses.

  • Pack-Level Engineering Only: We don't sell raw cells and random accessories. We dedicate 100% of our expertise to pack assembly, BMS integration, and system safety.

  • Tier-1 Grade-A Cells: We source exclusively from top-tier manufacturers (Samsung, LG, Panasonic, EVE, Molicel) to guarantee the longevity and reliability of your product.

  • Compliance First: Shipping lithium batteries legally is hard. We handle IATA, IMDG, and DOT regulations with UN-specification packaging, so you don't have to worry about customs seizures.
