Send Your Battery RequirementsFull-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 Before Delivery
For custom LiPo battery projects, poor coating consistency, weak tab or PCM welding, unstable protection settings, connector polarity errors, pouch appearance issues, or incomplete QC records may cause unstable runtime, charging problems, swelling risk, installation errors, or shipment disputes. Before delivery, THOR Power reviews production QC records and inspection reports again as part of our standard quality control process to improve traceability and reduce project risks.
LiPo Cell Manufacturing Process QC
Slurry preparation, electrode coating, calendering, slitting, stacking, pouch packaging, electrolyte filling, formation, degassing, and sealing records can be 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.
Factory quality control continues from LiPo cell manufacturing to final shipment review. Production QC record review, electrical performance testing, PCM protection confirmation, connector polarity inspection, pouch appearance review, labeling, packing inspection, and shipment document review help make OEM LiPo battery projects safer and more consistent.

Find answers to common custom LiPo battery questions about battery size selection, 3.7V LiPo battery replacement, connector and PCM customization, high-discharge LiPo battery options, sample testing, and OEM/ODM project support.
The right custom LiPo battery size should be selected based on available internal space, required runtime, discharge current, connector position, and assembly structure. A larger capacity does not always mean a better solution if the battery becomes too thick, difficult to install, or unsafe for the device structure. THOR Power can review your available thickness, width, length, and product layout to recommend a suitable LiPo battery size for sample testing.
Yes. Many OEM customers do not know the exact LiPo battery model number at the beginning. If you can provide the available battery space, product application, target runtime, charging method, and connector position, our team can help estimate suitable LiPo battery dimensions, capacity range, PCM protection, and connector layout before sample development.
Yes. For 3.7V LiPo battery projects, connector type, wire length, wire gauge, polarity, output direction, and PCM protection can be customized according to the device assembly and charging requirements. Before sampling, we usually review connector position, positive and negative polarity, wire routing, and PCM protection needs to reduce assembly mistakes and safety risks.
A 1000mAh LiPo battery may perform differently depending on device power consumption, discharge current, working temperature, PCM protection settings, charging method, and battery cell quality. Runtime is not determined by capacity alone. For custom projects, THOR Power reviews load current, peak current, device working mode, and safety requirements to help match a more suitable LiPo battery instead of selecting capacity only by number.
Selected high-discharge LiPo battery models can support high current output, and some models may be designed up to 60C according to cell type, size, structure, and application requirements. However, not every LiPo battery can reach 60C. For RC models, drones, FPV devices, and other high-current products, we need to review discharge current, burst current, battery size, heat generation, connector, and safety requirements before recommending a high-discharge LiPo battery solution.
Before replacing an existing LiPo battery, you should check battery size, voltage, capacity, connector type, wire polarity, PCM protection, charging method, and available installation space. Even if two LiPo batteries have the same voltage and capacity, differences in thickness, connector direction, protection board, or wire polarity may cause assembly or safety problems. THOR Power can help review replacement battery requirements before sampling.
To avoid wrong LiPo battery selection, you should confirm device space, runtime target, load current, connector layout, PCM protection, charging compatibility, and sample test results before mass production. THOR Power supports battery selection review, sample testing, specification confirmation, and pre-production checks to help reduce project risk before batch supply.
To receive a custom LiPo battery recommendation, you can send us the available battery space, required voltage and capacity, application, working current, peak current, connector type, wire length, PCM protection needs, quantity, and certification or shipping requirements. If you are not sure about some details, our team can help review your project step by step.
