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.
