This product is a compact battery pack composed of high-quality lithium-ion cells (model 18650). Utilizing an advanced "3 series 1 parallel" (3S1P) connection method, three standard 18650 cells are connected in series to achieve a standard voltage output of 11.1V, while the parallel connection of the individual cells ensures a stable capacity of 3200mAh. The battery pack integrates a high-performance intelligent protection board and comes pre-wired with leads and terminals, allowing users to connect and use it directly, greatly simplifying the integration process. Its compact size (only 19*56*68mm) allows it to be easily embedded in various devices with space constraints, making it an ideal power solution for portable electronic devices.

Product Precautions
Dedicated Charger: Always use a lithium-ion battery balancing charger (12.6V) that matches the battery pack's specifications. Do not use lead-acid battery chargers or other incompatible power sources for direct charging.
Prohibited Actions: Do not short-circuit, disassemble, puncture, incinerate, or throw the battery into fire. Avoid using and storing the battery in high-temperature (such as inside a car in direct sunlight) or humid environments.
Operating Environment: Avoid using the battery in extremely hot or cold environments to prevent performance degradation or damage.
Storage Requirements: If not used for an extended period (more than 3 months), it is recommended to maintain the charge level at approximately 50% and store it in a cool, dry place. Perform a charge and discharge cycle every 3 months for maintenance.
Installation and Fixing: When installing the battery pack in a device, ensure it is securely fixed to prevent severe vibration, and ensure good contact at the terminals.
FAQ
Q1: Can this battery pack directly power my device?
A: Yes. This product has an integrated protection board and output wires. As long as your device's operating voltage is within the battery pack's operating voltage range (approximately 12.6V-9.0V) and its power consumption does not exceed the maximum continuous discharge current, you can connect and use it directly. Please ensure the device's polarity is correct.
Q2: What charger should I use?
A: You must use a lithium battery charger with a voltage of 12.6V and a recommended charging current of 1.6A (or less) (3-series ternary lithium battery balance charger). Using the wrong charger will lead to overcharging and cause danger.
Q3: What is the approximate lifespan of the battery pack?
A: Under normal operating conditions (room temperature, standard charging and discharging current, and no complete over-discharge), the battery pack has a cycle life of over 500 cycles (capacity degradation to 80% of the initial capacity). The actual lifespan is affected by usage habits and environmental factors.
Q4: Can I use multiple battery packs in parallel or series?
A: This is strongly discouraged for non-professionals. Direct parallel or series connection requires the battery packs to have highly consistent voltage and internal resistance, and requires additional external balancing and protection circuits. Otherwise, it is very easy to damage the battery or even cause danger. If you need a larger capacity or voltage, please customize it before purchasing.
Q5: What are the transportation and storage restrictions?
A: According to international transportation regulations, lithium batteries are restricted items for transportation. The charge level usually needs to be below 30% during transportation. Air transportation must comply with IATA regulations. For storage, please refer to item 4 of the precautions.
