Features:
Voltage Characteristics
A single 18650 Li - ion battery typically has a nominal voltage of around 3.7V. Battery packs can be configured in series or parallel to achieve different voltage and capacity requirements. For example, two 18650 batteries in series can provide a 7.4V output, which is suitable for powering devices that require a higher voltage. In parallel configuration, the capacity is increased while the voltage remains the same as that of a single cell.
The voltage output of 18650 battery packs remains relatively stable during the discharge process, especially when compared to some other battery chemistries. This stability is crucial for the proper operation of electronic devices, as many components have specific voltage requirements.
Safety Features
Most 18650 Li - ion battery packs come with safety features such as over - charge protection, over - discharge protection, and short - circuit protection. The over - charge protection circuitry prevents the battery from being charged beyond its safe limit, which could lead to damage or even a safety hazard such as over - heating or explosion. Over - discharge protection ensures that the battery is not drained too low, which can affect its lifespan and performance.
Short - circuit protection is also vital. If a short - circuit occurs, the protection mechanism in the battery pack quickly cuts off the current to prevent damage to the battery and the device it powers.
Wide Operating Temperature Range
18650 Li - ion battery packs can generally operate within a relatively wide temperature range. While their performance may be affected at extreme temperatures, they can still function in conditions from - 20°C to 60°C. In cold temperatures, their capacity may decrease, but they can still provide some power. In hot temperatures, with proper safety measures in place, they can continue to operate. This makes them suitable for a variety of applications, including outdoor and industrial use.
