THOR Power develops custom LiPo battery solutions for compact electronic devices, matching battery size, capacity, discharge current, connector layout, PCM protection, and OEM assembly requirements.
Custom LiPo Engineering & Integration
Each custom lithium polymer battery is reviewed around size fit, power output, protection design, sample testing, and long-term OEM supply.
Custom LiPo Battery Specifications for Your Device
Custom LiPo battery specifications should be matched with real device space, runtime target, working current, connector position, PCM protection, assembly structure, and sample testing requirements before mass production.
Built Around Your Device Requirements
A suitable LiPo battery is not selected only by voltage and capacity. THOR Power reviews device space, runtime target, working current, connector position, PCM protection, charging method, and assembly structure before recommending a custom battery specification.
Size & Thickness
Battery thickness, width, length, and pouch cell structure can be adjusted according to internal device space.
Capacity & Runtime
Capacity can be matched according to target runtime, product size, discharge current, and safety requirements.
Voltage Platform
Single-cell 3.7V LiPo batteries and customized pack voltage can be reviewed according to product power design.
Connector & Wire
Connector type, wire length, wire gauge, polarity, and output direction can be customized for device assembly.
PCM Protection
PCM protection can be configured for overcharge, over-discharge, overcurrent, short-circuit, and charging safety.
Tabs & Output Direction
Metal tabs, soldering position, and output direction can be reviewed for compact or special assembly structures.
Label & Packaging
OEM label, model information, warning marks, heat shrink, and packaging details can be prepared according to project needs.
Sample Testing Support
Sample testing, specification confirmation, and pre-production review help reduce risk before mass production.
Full-Process Quality Control for Custom LiPo Batteries
THOR Power applies strict quality control across key production steps from slurry preparation, electrode coating, calendering, slitting, stacking, pouch packaging, electrolyte filling, formation, degassing, aging and capacity grading to PCM welding, connector assembly, electrical testing, packing, and final shipment review.
Reduce Quality Risks Across the Full Production Process
For custom LiPo battery projects, quality risks may come from coating consistency, tab or PCM welding, protection settings, connector polarity, pouch appearance, electrical performance, packing, and shipment details. THOR Power runs full in-house QC on every custom LiPo battery pack — pouch sealing, dimensional accuracy, and capacity testing before shipment.
LiPo Cell Manufacturing Process QC
Slurry preparation, electrode coating, calendering, slitting, stacking, pouch packaging, electrolyte filling, formation, degassing, and sealing records are reviewed as part of the LiPo cell manufacturing quality process.
Aging, Capacity Grading & Electrical Testing
Aging, capacity grading, voltage, internal resistance, charging status, discharge performance, and runtime consistency are checked to reduce power mismatch and batch variation risks.
PCM Welding, Connector & Polarity Review
PCM protection, tab welding, soldering, connector type, wire length, polarity, insulation, and output direction are reviewed to reduce protection mismatch and device integration risks.
Final QC Report & Shipment Review
Before delivery, production QC records, inspection reports, pouch appearance, sealing, label, heat shrink, packing method, carton mark, and shipping documents are reviewed again for project traceability.

Custom LiPo Battery FAQ for Electronic Device Applications
Find answers about custom LiPo battery size selection, 3.7V voltage options, connector and wire customization, PCM/BMS protection, high-discharge LiPo battery performance, sample testing, and battery integration for electronic devices, GPS trackers, IoT devices, medical devices, RC models, and wearable products.
How do I choose the right custom LiPo battery size for an electronic device?
The right custom LiPo battery size should be selected based on internal device space, required runtime, working current, peak current, connector position, PCM protection, and assembly structure. A larger capacity is not always better if the battery becomes too thick, difficult to install, or unsuitable for the device structure.
Can you help if I only know the battery space but not the LiPo model number?
Yes. If you provide the available battery space, device application, target runtime, charging method, working current, and connector position, THOR Power can help estimate a suitable LiPo battery size, capacity range, PCM protection, and connector layout before sample development.
Can a 3.7V LiPo battery be customized with connector, wire length and PCM protection?
Yes. A 3.7V LiPo battery can be customized with different connector types, wire length, wire gauge, polarity, output direction, PCM protection, NTC, label, and packaging according to device assembly and charging requirements.
What is the difference between a LiPo pouch cell with tabs and a LiPo battery with connector?
A LiPo pouch cell with tabs is usually used for PCB welding or further pack integration, while a LiPo battery with connector is normally ready for device installation after adding wires, connector, PCM protection, polarity confirmation, label, and insulation.
Why does the same 1000mAh LiPo battery perform differently in different devices?
A 1000mAh LiPo battery may perform differently depending on device power consumption, working current, peak current, discharge rate, temperature, connector resistance, PCM protection settings, and power management design. Runtime should be evaluated based on real device load, not capacity alone.
What does a high discharge rate mean in LiPo batteries?
The discharge rate shows how much current a LiPo battery can deliver compared with its capacity. Higher C-rate LiPo batteries may support stronger burst power for RC models, drones, FPV devices, or high-current products, but the cell capability, heat generation, connector, PCM/BMS design, and safety requirements must be reviewed.
What should I check before replacing an existing LiPo battery in my product?
Before replacing an existing LiPo battery, check the original battery size, voltage, capacity, connector type, wire length, polarity, PCM protection, discharge current, charging method, and available installation space to avoid connector mismatch, charging issues, assembly problems, or safety risks.
What information is needed for a custom LiPo battery quotation or sample recommendation?
For a custom LiPo battery quotation or sample recommendation, please provide the device application, battery size limit, voltage, capacity, working current, peak current, connector type, wire length, PCM/BMS requirements, quantity, label or packaging needs, and shipping or certification requirements.
