Li-ion polymer battery 19.24wh

Product Description
Power Cylindrical 18650 Li-ion Polymer Battery Pack
3.7V / 7.4V 2600mAh 19.24Wh 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
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.
