654060 3.7v 2000mAh 7.4wh Rechargeable Lithium Polymer Battery Cell For Speakers

Flat and slim design, perfectly suited for the compact layout of outdoor equipment

The soft-pack form factor eliminates the need for a rigid shell, allowing for flexible integration into the confined spaces of devices such as handheld weather devices, portable water quality analyzers, and small walkie-talkies. This significantly reduces the overall thickness and weight of the device, meeting the core requirements of "portability" in outdoor scenarios and minimizing the burden on outdoor trips.

A perfect balance of 7.4Wh energy and volume, suitable for intermittent outdoor use

With a 2000mAh capacity and 7.4Wh of energy, it offers a medium-sized balance between lightweight design and battery life: for low-power outdoor devices (such as portable altimeters and outdoor temperature and humidity recorders), a single charge can support 5–10 days of intermittent operation; for medium-power devices (such as small outdoor flashlights and portable Bluetooth beacons), it can provide 8–12 hours of continuous use. This avoids the inconvenience of frequent charging with small-capacity batteries while avoiding excessive size and weight due to the pursuit of high capacity.

3.7V Nominal Voltage, Highly Compatible with Outdoor Equipment Power Supply Systems

The 3.7V voltage of a single cell directly matches the motherboard power supply logic and charging management chips of most portable outdoor devices, eliminating the need for additional boost/buck circuits. This not only simplifies the device's circuit design and reduces hardware failure rates but also reduces energy loss during voltage conversion, indirectly improving the device's actual battery life, making it particularly suitable for outdoor scenarios without stable charging conditions.

Strong Wide Temperature Tolerance, Adaptable to Complex Outdoor Climates

One of the core advantages of ternary lithium materials is their excellent high and low temperature performance. This battery model can stably discharge within a temperature range of -20℃ to 60℃: in low-temperature outdoor environments (such as mountainous areas and high-altitude regions), it can still maintain a discharge efficiency of over 70%, ensuring the normal operation of outdoor testing instruments and walkie-talkies; in high-temperature outdoor environments during summer, it is less prone to sudden capacity drop or thermal runaway risks, far exceeding the environmental adaptability of lithium cobalt oxide and lithium iron phosphate batteries of the same specifications.

High safety with a soft-pack structure, resistant to outdoor impacts and pressure.

Utilizing aluminum-plastic film soft-pack encapsulation, it eliminates the "explosion risk" of hard-shell batteries. Even in the event of impacts, pressure, or minor punctures outdoors, the battery will only bulge, without causing violent combustion or explosion. Its safety is far superior to cylindrical or prismatic hard-shell batteries. This characteristic is particularly important for outdoor hiking and mountaineering, reducing safety hazards caused by equipment malfunctions.

Long cycle life, reducing long-term maintenance costs for outdoor equipment.

The long cycle life of ternary lithium materials means that for equipment requiring long-term outdoor use (such as sensor terminals in outdoor monitoring stations and portable geological exploration equipment), frequent battery replacements are unnecessary, reducing the frequency and cost of maintenance for outdoor equipment. This is especially suitable for equipment used in remote outdoor environments.
