Testing Lithium Polymer Batteries
1. Locate the wire on the balancer
connector that
corresponds with the pack negative (-) lead.
This is
usually the black wire at the edge of the connector.
2. Plug the connector in to the
pins on the side of the
voltage display with the
negative lead towards the bottom
3. The LED display should
light up and display the voltage of the
first cell. The
decimal point (dot) on the display indicates
which cell
is being measured. The rightmost dot on
the display
indicates cell 1. The “350” shown on the display
indicates 3.50 volts.
4. In a few seconds, the display will
change
to read the voltage of the second cell,
and the middle dot on the display will
light up (indicating cell 2).
5. On a
3-cell or larger pack, the display will
change to read the voltage of the third
cell and the left-most dot will light up
(indicating
cell 3). On a 2-cell pack, the
display will read “no” instead of showing
the voltage.
6. The sequence repeats continuously.
Allow a few
cycles for the voltage to stabilize.
7. To read higher-cell count packs,
simply plug the monitor in as shown
here with the positive-most lead in
the top pin. The display will show
the voltages of the top three cells of
the pack. The picture shows a 5 cell
pack plugged
into the display reading cells 3, 4, and
5.
Testing NiCd/NiMH
Batteries
1. To test a NiCd/NiMH
receiver pack, plug it in as
shown here. The display will indicate the
total pack
voltage – not the voltage of the individual
cells. The
display supports up to 10 cell NiCd/NiMH packs. Do
not connect a larger pack than this.
Additional Notes
1. If the voltage shows over 4.5V,
then the pack is not
properly connected to the display, or the
balancer
connector is wired incorrectly.
2. Always disconnect your battery
from the display when
finished checking the voltage.
