What We Can Customize

Custom Battery Details Built Around Your Device Requirements

OEM/ODM battery projects often require more than changing a size or connector. THOR Power reviews your device space, electrical load, protection logic, assembly method, branding needs, and delivery requirements before recommending a manufacturable battery solution.

From Custom Design to Long-Term Supply

We support OEM/ODM customization for LiPo pouch batteries, lithium-ion battery packs, 18650 / 21700 battery packs, and project-based rechargeable battery solutions.

Whether your project needs a compact battery for a new device, a replacement battery upgrade, a private label product, or a long-term mass production solution, our factory can review the technical details and support practical battery development.

Project Types We Support

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

Customer Pain Point Battery size, voltage, capacity, connector, PCM/BMS, and runtime are not fully finalized during early product design.

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 Size Matching Runtime Review Sample Development PCM/BMS Design

Battery Replacement & Upgrade

Customer Pain Point Original batteries may be discontinued, underpowered, unstable in supply, or mismatched with connector and polarity requirements.

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.

Capacity Upgrade Connector Change Structure Review Supplier Replacement

Private Label Battery Supply

Customer Pain Point Brand owners need consistent labels, logo, packaging, product codes, carton marks, and repeat-order presentation.

THOR Power supports OEM label design, specification confirmation, packing consistency, and repeat-order production for private label lithium battery and branded battery supply projects.

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.

Batch Consistency QC Records Repeat Orders Long-Term Supply

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 & Document Support

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.

Cell Production QC Records Coating, calendering, slitting, stacking or winding, pouch packaging, electrolyte filling and sealing records review.
Welding & Assembly Inspection Tab welding, nickel strip welding, wire soldering, holder, casing, insulation and pack structure inspection.
PCM / BMS Protection Verification Overcharge, over-discharge, over-current, short-circuit, temperature protection and balancing review.
Electrical Performance Testing Voltage, capacity, internal resistance, charging status, discharge performance and output stability check.
Aging & Capacity Grading Aging, capacity grading, batch matching and consistency review before mass production shipment.
Final Packing & Shipment Review Appearance, label, heat shrink, packing method, carton mark and shipment document review.

Risk-Based FAQ

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.

Wrong Battery Selection Runtime Target Working Current Battery Type Review
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.

Sample Approval Mass Production Battery BOM Batch Consistency
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.

Battery Supplier Replacement Replacement Lithium Battery Connector Change 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.
