Engineered specifically for high-torque motorized applications like fascia massage guns, this 7.4V 1000mAh lithium-ion battery pack delivers sustained, fade-free power in a highly compact form factor. Constructed utilizing a 2-series, 1-parallel (2S1P) configuration of premium 14500 cylindrical cells, it is designed to fit perfectly into the tight handle compartments of handheld percussive massagers. The exterior is tightly bound in a thermally resilient PVC shrink wrap, offering a smooth, protective layer that dampens internal device vibrations while maintaining structural integrity.
At the core of this power solution is a precision-engineered integrated protection circuit board (PCB), seamlessly spot-welded to the cells and terminating in flexible, silicone-insulated output wires. This 7.4Wh capacity design optimally balances spatial constraints with reliable energy output, ensuring your motorized devices maintain consistent percussive force without premature voltage drops. The robust insulating packaging materials and comprehensive multiple-layer protection—guarding against overcharge, over-discharge, short-circuit, and overcurrent events—significantly extend the operational lifespan and guarantee the absolute safety of the connected equipment.

To meet specific market demands, we offer flexible cell sourcing, including reliable domestic options or internationally recognized Tier-1 brands such as Samsung, LG, and Sanyo for premium device lines.
Stable Voltage Platform for Motorized Devices: The 2S configuration establishes a rock-solid 7.4V output. This is crucial for fascia guns, preventing the stalling, stuttering, or loss of amplitude often experienced with lower-voltage alternatives during deep tissue application.
Rigorous Quality Control & Testing: Every individual battery pack undergoes an exhaustive testing protocol before dispatch. This includes precise internal resistance matching, comprehensive charge/discharge aging cycles, and mechanical drop tests, ensuring exceptional batch-to-batch consistency and a near-zero defect rate.
Comprehensive Safety Protection: The built-in, precisely calibrated protection board acts as a vigilant safeguard, actively monitoring circuitry to instantly cut off power under abnormal operating conditions, thereby neutralizing potential thermal or electrical risks.
Customizable Plug-and-Play Integration: Supplied pre-wired with stripped bare ends as standard, the terminal connections can be fully customized with JST, XT30, or proprietary connectors to match your specific assembly line requirements, drastically reducing manufacturing complexity.
Superior Craftsmanship & Vibration Resistance: Utilizing automated laser spot welding, the nickel strip connections exhibit ultra-low internal resistance and exceptional mechanical strength. This robust construction easily withstands the intense, repetitive vibrations generated by percussive massage mechanisms.

Professional Packaging for Transit: To ensure absolute safety during global transit, all battery packs are secured in anti-static blister trays or individual reinforced safety boxes. We strictly adhere to international maritime and aviation regulations for dangerous goods packaging.
Charging Requirements: Please mandate the use of a dedicated lithium battery balance charger and ensure the charging voltage strictly does not exceed 8.4V. Avoid using inferior, non-calibrated, or incompatible chargers to prevent cell degradation.
First Use Activation: It is highly recommended to fully charge the battery prior to its initial deployment to activate the chemical components and achieve optimal discharge performance.
Thermal Management: Charging and discharging must remain within the specified temperature parameters. Avoid operating or storing the battery in environments with extreme heat (such as direct sunlight or adjacent to industrial heaters) or freezing temperatures.
Physical Integrity: Prevent the battery pack from sustaining strong mechanical impacts, punctures, crushing forces, or structural deformation. Under no circumstances should the PVC casing or protection board be manually disassembled.
Short Circuit Prevention: Ensure that the stripped terminal wires do not come into direct contact with each other or conductive surfaces, which would trigger a short circuit. Apply proper heat shrink or electrical insulation during the final device assembly process.
Storage Recommendations: If the pack is to remain dormant for an extended period (exceeding one month), adjust the charge level to approximately 50%-60% capacity. Store in a climate-controlled, dry environment, and implement a routine voltage check every 30 days.
Prohibited Actions: It is strictly forbidden to expose the battery to open flames, submerge it in liquids, attempt unauthorized modifications, or force a discharge current exceeding the maximum 2C rating.
A1: Theoretically, the runtime (in hours) is calculated by dividing the battery capacity (1000mAh) by the device's continuous operating current (mA). For instance, a fascia gun drawing an average operating current of 200mA will yield a theoretical runtime of approximately 5 hours. Please note that actual runtime will fluctuate based on variable discharge rates (e.g., applying higher pressure with the massager) and ambient operating temperatures.
A2: No. Standard mobile phone chargers output a 5V direct current, whereas this specific 2S battery pack requires an 8.4V dedicated lithium battery charger to reach full capacity. Utilizing an incorrect charger will result in a failure to charge, potential irreversible damage to the cells, and significant safety hazards.
A3: This unit supports a maximum safe charging current of 1C (1000mA), allowing it to be fully replenished in approximately 1 to 1.5 hours. Pushing a charging current higher than this specification is strongly discouraged, as it accelerates thermal buildup, degrades the chemical structure, and compromises overall safety.
A4: This product is engineered with a standard protection board integrated into every unit. You can verify this through several methods: 1) The physical profile features a slightly rigid, flat section encapsulated near the wire leads; 2) If the battery experiences an over-discharge event, the board will cut the output to 0V when connected to a load, but normal voltage will immediately recover once connected to an 8.4V charger.
A5: Parallel connection by end-users or non-specialized assembly lines is strictly not recommended. Self-parallel connections often lead to circulating currents caused by minute differences in internal resistance and baseline charge levels, which severely impacts performance and safety. If your application demands a larger capacity, we recommend utilizing our custom engineering services for a purpose-built specification.
A6: This scenario typically indicates that natural self-discharge has caused the voltage to drop below the safety threshold, prompting the protection board to enter a locked state. Attempt to connect the designated 8.4V charger for an extended duration (e.g., 30 to 45 minutes). The protection circuitry is designed to recover once it detects a stable, sustained input voltage. If the unit remains unresponsive, do not attempt to dismantle the casing; please contact our technical support team.
A7: Lithium-ion batteries are classified as dangerous goods. Transportation must strictly adhere to relevant international regulations, including IATA guidelines for air freight. To facilitate this, our battery packs hold comprehensive UN38.3 and MSDS certifications. When arranging logistics, contents must be declared truthfully, and the battery must be in a stable state (typically shipped at a partial charge with fully insulated terminals).
