Technical Parameters

Product Uses & Device Matching

Engineered as a capacity-focused power source, this 3.6V 3200mAh pack operates with a maximum continuous discharge rate of 1C (3.2A). This specific discharge boundary makes it perfectly tailored for medium to low-power consumption devices that prioritize extended, stable runtime over sudden bursts of high current. It serves as an ideal portable DC power solution for a diverse array of applications:

• Consumer Electronics & Audio: Specifically optimized for children's story-telling devices, providing steady audio playback. Also highly suitable for backup power supplies, portable fans, LED flashlights, headlamps, electric toys, and digital cameras.

• DIY Projects and Makers: Acts as a reliable energy backbone for educational robots, drones (requires multiple units configured appropriately), Arduino/Raspberry Pi projects, and small mobile computing devices that require stable, long-lasting voltage.

• Precision Instrumentation: Ensures accurate readings by delivering clean, uninterrupted power to handheld measuring devices, environmental test instruments, and smart utility meters.

• Communication Equipment: Powers walkie-talkies, portable radios, and emergency broadcasting equipment, ensuring communication lines remain open during critical moments.

• Alternative Energy & Others: Functions effectively in small-scale solar energy storage systems, specific e-cigarette models (matching the 1C limit), and various personal care appliances.

Product Precautions & Storage Guidelines

• Charging Requirements: Always use a dedicated charger specifically designed for lithium-ion/lithium-polymer batteries with a precise output voltage of 4.2V. Employing lead-acid battery chargers or incompatible adapters is strictly prohibited, as it fundamentally compromises the cell chemistry and can lead to overheating, fire, or explosion.

• Prohibited Actions: Maintain the physical integrity of the outer shrink wrap. Do not short-circuit the battery's positive and negative terminals, forcibly disassemble the pack, puncture the casing, throw it into a fire, or subject the unit to severe mechanical shocks.

• Bulk Storage & Environmental Adaptation: For large-scale inventory management, avoid storing the batteries in high-temperature (such as near heat sources) or highly humid environments. To minimize capacity degradation during prolonged inactivity, maintain the battery at a 40% to 60% State of Charge (SOC) and store it in a climate-controlled, dry facility at room temperature.

• System Compatibility: Verify that the battery pack's nominal voltage, total capacity, and 3.2A discharge limit align perfectly with your hardware's power draw. Overloading the battery beyond its 1C rating will trigger the protection board and interrupt power.

• Handling Abnormalities: Should you detect any unusual heat generation, physical swelling, chemical leakage, or an atypical sweet/metallic odor from the electrolyte, immediately cease operation. Isolate the affected unit in a fire-safe, ventilated area.

• Responsible Disposal: After the battery reaches the end of its lifespan, do not dispose of it indiscriminately in standard waste streams. Strictly adhere to local environmental regulations for proper recycling and material recovery.

Frequently Asked Questions (FAQ)

Q1: Can this battery be used directly? Or do I need to add a protection board myself?

A1: This product is a fully integrated, ready-to-deploy unit. It arrives with an intelligent protection board, insulated wiring, and specified terminal connectors already securely installed. Because it has an integrated protection board and pre-connected cables, it can be used directly after purchase without any additional internal circuitry configuration, drastically reducing your assembly time.

Q2: What does the nominal capacity of 3200mAh mean?

A2: The milliampere-hour (mAh) metric defines the total energy reservoir. In theoretical terms, a 3200mAh rating indicates the cell can sustain a 3200mA (3.2A) current draw for exactly 1 hour; or at a lower current of 160mA for approximately 20 hours. Your actual real-world runtime will scale inversely depending on the active power consumption (current) of your specific device.

Q3: How long does it take to charge?

A3: Replenishment speed is dictated by your charger's output rating. For example, utilizing a standard 1A (1000mA) charger to charge a completely depleted 3200mAh battery will take approximately 3.5 to 4 hours (factoring in standard energy conversion losses). For optimal battery health and longevity, it is highly recommended to use a charger with a current within the 0.5C-1C window.

Q4: Can the battery handle high current discharge?

A4: This specific product utilizes a conventional capacity-focused 18650 cell, with a maximum continuous discharge current typically capped around 1C (i.e., approximately 3.2A). This makes it exceptionally well-suited for medium and low power consumption devices. If your engineering requirements involve powering high-drain devices (such as high-lumen tactical flashlights or RC model vehicles), please contact our team to explore options regarding our high-rate (power type) battery alternatives.

Q5: How do I distinguish between the positive and negative terminals of the output wires?

A5: Industry-standard color coding is applied: typically, the red wire represents the positive terminal (+) and the black wire indicates the negative terminal (-). Despite this visual guide, for absolute safety and to prevent component damage, please be sure to use a calibrated multimeter to confirm polarity before final circuit connection.

Q6: Does the battery pack support series or parallel connection to obtain higher voltage or capacity?

A6: Yes, configuring multiple cells is possible, but it requires professional electrical knowledge and careful operation.

Series connection (voltage addition): Connecting the positive and negative terminals of multiple batteries of the same specifications in series will result in a higher voltage (e.g., 2 batteries in series will give 7.4V). It is absolutely essential to ensure that the voltage, capacity, and internal resistance of each battery are highly consistent. Furthermore, it is strongly recommended to equip the entire series-connected battery pack with a comprehensive balancing protection board.

Parallel connection (capacity addition): Connecting multiple batteries of the same specifications with their positive terminals together and negative terminals together increases the total capacity (e.g., two batteries in parallel yield 6400mAh), while the baseline voltage remains unchanged. This also requires that the battery cell parameters are perfectly identical to prevent uneven current sharing.

For maximum safety and performance, especially for non-professional users or large-scale deployments, we highly recommend purchasing our custom-engineered, pre-assembled and tested multi-cell battery pack (PACK) products rather than attempting manual configurations.
