Built Around Custom Battery Pack Manufacturing
PackForge Energy is built for B2B customers who need custom lithium battery packs instead of standard catalog batteries.
Our factory work focuses on practical PACK manufacturing: reviewing application requirements, confirming battery configuration, matching suitable cells and BMS options, assembling battery packs, checking key functions and preparing the documents needed for international shipment.
We serve customers developing industrial equipment, energy storage systems, light electric vehicles and portable field equipment that require reliable, project-specific battery pack solutions.
Certifications & Compliance Support
Lithium battery projects require clear documentation before international shipment. PackForge Energy supports B2B customers with battery-related test reports, certification documents and export documentation based on the selected cell model, battery pack configuration, destination market and project requirements.
Our Battery Pack Manufacturing Facility
Pack assembly, BMS integration, testing and export preparation for custom lithium battery projects.
Our factory supports custom lithium battery pack assembly, BMS integration, functional testing and export preparation for industrial and OEM battery projects.
02
Cell Grouping & Pack Configuration
Battery pack configuration support using cylindrical cells, prismatic cells and project-specific pack structures.
03
BMS Matching & Integration
BMS selection and installation for protection, balancing, communication and battery management functions required by the project.
04
Testing & Inspection
Functional checks before shipment, including charge-discharge review, BMS function check, appearance inspection, wiring review, packaging review and project-specific test coordination.
05
Export Preparation
Support for lithium battery export documents, packaging review and Class 9 dangerous goods shipping coordination.
Engineering Communication & Project Confidentiality
Custom battery pack projects require clear communication before quotation, sampling and batch production. PackForge Energy supports overseas B2B customers with English project communication, engineering-oriented requirement review, NDA support and fast initial response.
English Project Communication
We support English communication for battery pack requirements, drawings, BMS functions, connector direction, testing needs, documentation and shipment preparation.
Engineering-Oriented Review
Before quotation, we review key project details such as application, voltage, capacity, discharge current, size limits, working environment, BMS requirements, target quantity and destination market.
NDA & Project Confidentiality
For OEM and ODM battery pack projects, PackForge can support non-disclosure agreements where required. Customer drawings, product information, application details and project files are handled as confidential project information.
1 Working Day Initial Response
For qualified B2B project inquiries with complete basic information, we aim to provide an initial project review or quotation direction within 1 working day.
Long-Term Project Support
PackForge supports more than one-time battery purchases. We can assist with sample development, adjustment feedback, batch production preparation, repeat supply and export documentation coordination for long-term B2B battery pack projects.
