WARNING:
Never touch with a ring
or a conductive object the poles
of the battery - RISK OF ELECTRIC
SHOCK!
Each LiFePo4 battery of Kunmpan
Electric is equipped with a separate
LCD display. At any time this display
indicates the current charge status of
the battery.
On top of the battery block is a silver
button.
If the button is pressed for several
seconds, the LCD display is activated.
First the 188 appears briefly.
These are all segments, which can be
shown in the display. If the 188 is not
fully indicated, the display is faulty.
If the button is pushed and hold for
a few seconds, the current charge
status appears in percentage.
An empty battery displays only a
few percentage points. A full battery
indicates 100%.
The display is only an indication of
the approximate charge status of the
battery, the mathematical accuracy is
around +/- 10%.
Especially during loading the display
will indicate 100% very rapidly
even if the real charge status has
only reached 10%. Just after a few
minutes of charging the LCD display
returns to normal status.
Also, the percentages rise slightly
immediately after using the battery.
They will return to a stable level after
a few minutes.
