Engineered for demanding portable applications, this high-performance cylindrical lithium-ion battery pack leverages premium 18650 cells as its foundational core. Utilizing a precision-welded "1 series 7 parallel" (1S7P) configuration, seven energy-dense cells are integrated to deliver a substantial 22400mAh capacity while maintaining a highly stable 3.7V nominal voltage. Holding this pack, you will immediately notice its dense, reassuring weight of approximately 350 grams and its remarkably compact footprint, measuring just 19x68x131mm. The exterior is tightly wrapped in a smooth, industrial-grade PVC heat shrink film that effectively resists abrasions, dust, and moisture ingress in unpredictable environments. Integrated directly into the assembly is an intelligent protection circuit board (PCB), complete with pre-soldered output wires and standard terminal connectors. This plug-and-play architecture ensures immediate deployment, providing extended, reliable power for devices operating in remote, challenging, or off-grid locations.
Unlike alternatives that suffer from rapid power drain or exaggerated specifications, this pack delivers a verified, full-blooded 22400mAh capacity. By utilizing low-internal-resistance cells paired with a highly efficient management board, it ensures maximum energy conversion. This translates to significantly longer operating times for your equipment in the field, minimizing the frequency of recharging cycles and keeping essential devices active when they are needed most.
Space is often at a premium in portable electronics. This unit maximizes power output within a strictly limited physical footprint. The tightly packed 18650 cells provide an exceptional energy-to-weight ratio, allowing engineers and product designers to integrate massive power reserves without compromising the sleekness or portability of the final device.
Safety and consistency are paramount for large-scale deployments. Every single batch undergoes 100% strict capacity grading, aging tests, and extreme temperature cycling before leaving the facility. The built-in PCB acts as a vigilant guardian, instantly cutting off the circuit to prevent overcharging, over-discharging, overcurrent, and short circuits, ensuring a zero-defect rate and absolute operational safety.
Arriving fully pre-assembled with cells, precise spot welding, protective packaging, and an integrated BMS, this pack eliminates secondary processing steps. Furthermore, we offer comprehensive OEM/ODM services to seamlessly match your specific structural designs. Wire lengths, casing materials, and terminal types (such as the secure click of a PH2.0 or XT30 connector) can be fully customized to fit non-standard equipment perfectly.
Constructed with carefully selected power cells, this unit is built to endure. Even after undergoing more than 500 deep charge and discharge cycles, the battery retains over 80% of its original capacity. This exceptional longevity drastically reduces long-term maintenance and replacement overhead for end-users, making it an incredibly cost-effective solution for commercial applications.

Always use a dedicated lithium-ion battery charger with matching voltage and current specifications (4.2V). Using lead-acid battery chargers or other incompatible types is strictly prohibited and may cause irreversible damage.
Do not attempt to peel the PVC wrapping, disassemble the internal structure, crush, or puncture the battery. Never expose the unit to open flames or intentionally short-circuit the positive and negative terminals.
Operate and store the battery in a dry, well-ventilated environment, safely away from localized heat sources and flammable or explosive materials. Avoid initiating charge or discharge cycles in temperatures exceeding the rated specifications.
Verify correct polarity during integration (the red wire is strictly positive, the black wire is negative). Ensure a firm, secure connection at the terminal block to prevent mechanical loosening and dangerous electrical sparking during vibration.
If the pack is to be stored for extended periods (more than 3 months), adjust the charge level to approximately 50% capacity. Store the unit in a cool, dry location to preserve cell chemistry and prevent deep discharge degradation.
Once the battery has completed its operational lifespan, do not dispose of it in standard waste streams. It must be recycled by a certified professional organization in strict accordance with local environmental regulations.
A: Yes. This battery pack maintains a nominal voltage of 3.7V and reaches a full charge voltage of 4.2V, which is completely consistent with the voltage characteristics of a single standard 18650 lithium-ion battery. It is fully compatible with any device engineered to run on a single-cell lithium architecture.
A: Theoretically, under identical load conditions, the 22400mAh capacity is indeed approximately 7 times that of a standard single 3200mAh cell, providing roughly 7 times the operational endurance. However, actual field battery life will always be influenced by dynamic variables such as device power consumption spikes and ambient discharge temperatures.
A: The intelligent protection board acts as the core safety mechanism. It functions as an automated guardian, instantly severing the circuit in the event of overcharging, over-discharging, or short circuits to prevent thermal events. Because we utilize a premium board with extremely low internal resistance, it will not noticeably restrict output performance as long as the draw remains within the rated current limits.
A: Long-term rapid charging is not recommended. To achieve optimal cell longevity and absolute safety, we advise using a 2A (approximately 0.1C) charger. Forcing excessive current into the pack will increase internal heating, accelerate chemical degradation, shorten its lifespan, and potentially pose safety risks. Always refer to the technical parameters for maximum charging thresholds.
A: No. The listed product dimensions (19*68*131mm) refer strictly to the maximum physical footprint of the wrapped battery pack itself. The output wires and attached terminals extend externally from this main body and must be accounted for in your device's internal cavity design.
A: The host device will typically feature an indicator. Alternatively, you can gauge the charge level by measuring the terminal voltage with a multimeter: a reading of approximately 4.2V indicates a full charge, while a reading dropping below 3.3V (nearing the protection board's cutoff threshold) signals that the unit requires prompt recharging. We strongly recommend integrating a low-battery warning function into your device's interface.
A: Absolutely. We provide comprehensive, up-to-date certification reports including UN38.3, MSDS, CE, and RoHS. These internationally recognized credentials guarantee compliance with stringent safety standards, facilitating smooth customs clearance and legal distribution across global markets.
Understanding the critical nature of safe transit for energy storage products, every shipment is prepared using stringent industrial packaging protocols. This ensures that large-scale deliveries arrive in perfect condition, ready for immediate integration without the risk of transit damage.
Each individual battery pack is hermetically sealed within a premium anti-static bag, preventing any electrical anomalies during transit while actively locking out environmental moisture, humidity, and dust.
The units are securely nested in custom-molded, flame-retardant isolation trays. This structural design absorbs physical impacts and prevents any friction, crushing, or movement between units during turbulent freight handling.
The internal trays are housed in heavy-duty, multi-layer corrugated export cartons, clearly marked with all required hazardous material handling labels to ensure full compliance with global air and sea freight regulations.
