We support project-based custom battery pack development for LiPo pouch batteries, Li-ion battery packs, 18650 / 21700 battery packs, and rechargeable battery solutions with special structure or interface requirements.
For new device projects, replacement pack development, private label projects, or repeat production supply, our factory reviews the technical details before sample development and long-term delivery.
Battery Parameters
Battery specifications are matched around device space, working current, runtime target, installation method, and application environment.
Protection & Control
Protection design is reviewed according to battery type, load demand, safety requirements, charging logic, and device operating conditions.
Assembly Details
Battery output, connection method, insulation, casing structure, and assembly details can be customized for easier device integration.
Labeling & Delivery Support
Labels, packaging, carton marks, specifications, shipping documents, and compliance files can be prepared according to project needs.

OEM/ODM Battery Projects We Support
Different battery projects face different risks: wrong battery selection, unstable supply, connector mismatch, or limited branding support. THOR Power supports project-based custom battery development for new devices, battery replacement upgrades, and private label battery supply.
New Device Battery Development
THOR Power helps review your device space, working current, charging method, and assembly structure before sample development, reducing the risk of wrong battery selection for new device projects.
Battery Replacement & Upgrade
We can review your original battery size, voltage, capacity, wire layout, polarity, PCM/BMS protection, and device structure to recommend a replacement or upgraded custom battery solution.
Private Label Battery Supply
THOR Power supports OEM label design, specification confirmation, packing consistency, and repeat-order production for private label lithium battery and branded battery supply projects.

OEM/ODM Battery Development Process
A clear development process helps reduce project risk. From requirement review and battery solution proposal to sample development, testing confirmation, mass production preparation, and long-term supply follow-up, THOR Power helps customers turn custom battery requirements into production-ready solutions.
Requirement Review
We review your device space, target voltage, capacity, working current, application environment, connector type, quantity, and certification needs before recommending a battery direction.
Battery Solution Proposal
Our team recommends a suitable battery type, cell configuration, PCM/BMS protection, connector layout, wire design, and assembly structure based on your project requirements.
Sample Development
After the solution is confirmed, we prepare custom battery samples for testing, including size, capacity, protection board, wire length, connector, polarity, label, and packaging details.
Sample Testing & Adjustment
Customers test the sample in real devices. If needed, we help adjust battery size, output method, wire length, connector type, protection logic, or assembly details before final confirmation.
Mass Production Preparation
Before production, we confirm specifications, BOM, label, packaging, inspection standards, production requirements, and shipping documents to reduce errors during batch production.
Long-Term Supply Follow-Up
After mass production starts, THOR Power supports batch consistency, quality records, packing control, repeat orders, and long-term supply follow-up for OEM/ODM battery projects.
Process control matters for custom battery projects. A structured OEM/ODM battery development process helps reduce wrong battery selection, sample delays, connector mismatch, mass production errors, and long-term supply risks.
Quality Control Across the Full Custom Battery Production Chain
Quality is controlled at every key production step, not only at final inspection. THOR Power reviews cell production, welding, PCM/BMS assembly, electrical testing, aging, capacity grading, packing, and shipment details for OEM/ODM battery projects.
Full Production Chain Quality Control
For custom battery projects, each key process is reviewed to reduce batch inconsistency, connector mismatch, electrical performance issues, packing errors, and long-term supply risks.
Documents & Shipping Support
For OEM/ODM battery projects, required documents and packing information can be supported according to battery model, order details, shipping method, and destination requirements.
- UN38.3 Support
- MSDS Support
- Battery Specification Sheet
- Product Label
- Packing Information
- Carton Mark
- Shipping Document Support
Note: Documentation availability may vary by battery model, certification status, order quantity, transportation requirements, and project needs.

OEM/ODM Battery Project FAQ
Custom battery projects often fail because of wrong battery selection, unclear electrical requirements, connector mismatch, poor sample-to-mass-production control, or unstable long-term supply. These FAQs help customers understand how to prepare an OEM/ODM lithium battery project and reduce avoidable development risks.
01 How can I avoid choosing the wrong battery for my device?
Choosing the wrong battery may lead to poor runtime, connector mismatch, charging problems, limited assembly space, overheating risk, or redesign costs. Before recommending a custom LiPo battery, lithium-ion battery pack, or 18650 / 21700 battery pack, THOR Power reviews device space, voltage, capacity, working current, peak current, charging method, protection requirements, and application environment.
02 What causes custom battery samples to fail during device testing?
Custom battery samples may fail because the working current is underestimated, connector polarity is incorrect, PCM/BMS protection settings are not suitable, wire length affects assembly, or the battery size leaves too little tolerance inside the device. During sample development, we review electrical load, connector layout, wire harness, protection logic, and real device assembly requirements to reduce sample testing problems.
03 How do you reduce the risk from sample approval to mass production?
After sample approval, we confirm specifications, BOM, battery structure, connector direction, wire length, polarity, label, packing method, inspection standard, and production requirements before batch production. This helps reduce sample-to-mass-production deviation, batch inconsistency, assembly errors, and shipment mistakes in OEM/ODM battery projects.
04 What should I check before replacing an old battery supplier?
Before replacing an old battery supplier, customers should confirm the original battery size, voltage, capacity, connector type, wire length, polarity, PCM/BMS protection, discharge current, charging method, and device assembly space. THOR Power can review the original battery information and recommend a replacement lithium battery solution with better long-term supply stability.
05 How do you support battery projects with strict size or structure limits?
For compact devices or special equipment with limited internal space, we review battery thickness, width, length, cell arrangement, wire outlet direction, connector position, PCM/BMS placement, insulation, and packing structure. The goal is to make the custom battery fit the device structure while meeting voltage, capacity, safety, and assembly requirements.
06 What affects the final cost of an OEM/ODM battery project?
The final cost of an OEM/ODM battery project is affected by battery type, cell size, capacity, voltage, discharge current, PCM/BMS design, connector and wire requirements, label and packaging, testing requirements, certification documents, order quantity, and shipping method. Providing complete project details helps us recommend a more practical and cost-effective custom battery solution.
