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.

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 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.
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.
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.
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.
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.
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.
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.
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.
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.
