Descrição do produto

Lithium Battery Cell 18650 Li-ion Battery Pack 3.7v 7.4V 2600mAh 19.24wh Power Lithium Batteries

Electrical Performance

Parameter	Specification
Nominal Voltage	7.4V (two 3.7V 18650 cells in series)
Operating Voltage Range	6.0V-8.4V
Rated Capacity	2600mAh (at 0.2C discharge rate)
Charging Voltage	8.4V standard
Charging Current	0.2C-1C (520mA-2600mA recommended)
Discharge Current	≤1C (2600mA) continuous, 2C (5200mA) peak
Cycle Life	≥80% capacity after 500 cycles, ≥60% after 1000 cycles
Internal Resistance	≤100mΩ (total pack including connections)
Safety Thresholds	Overcharge: 8.7±0.05V, Over-discharge: 5.5±0.1V

Key Advantages for Heating Devices

Strong Voltage Adaptability: 7.4V matches most small heating elements without additional transformers, reducing energy loss and device size
Stable Power Output: Series structure provides stable voltage platform with slow voltage drop during discharge
Balanced Capacity: 2600mAh provides 1.9-3.8 hours of continuous heating for 5-20W devices
Standardized Design: Mature 18650 production ensures consistent parameters and reliable performance
Compact Size: 18mm diameter, 65mm length fits portable heating devices
Safety Features: Integrated protection boards with multiple safeguards against overcharge, over-discharge, and short circuits
Cost-Effective: Mass production lowers costs compared to custom battery solutions

Applications

Electric Tools: Clippers, drill saws - provides sustained power output
Audio Equipment: Portable speakers - ensures stable voltage for clear sound
Portable Electronics: Laptops, power banks - high-capacity energy storage
Energy Systems: Solar/wind energy storage units
Medical Devices: Portable monitors requiring long battery life

Safety Information

Overheating Risk

Battery packs operate within specific temperature ranges. Malfunctioning temperature control can lead to thermal runaway - a chain reaction causing rapid heat generation, potentially resulting in fire or explosion.

Pressure Build-up

Excessive heat causes battery swelling from internal pressure increases. Severe cases may lead to electrolyte leakage, which is flammable and corrosive, posing fire and chemical burn risks.
