---- BALANCER MODE (Lithium types only)
Try it out with a LITHIUM battery pack which has the proper Balance Connector attached. Attach the charger to an appropriate
DC power supply, and connect your battery pack’s main and balance connectors to charger as previously described.
Press the
MODE
button until you reach the
BALANCER
Mode screen.
*Press
DOWN
once to reach the SELECT VOLTAGE screen. This screen simply shows you a very accurate voltage for each cell in
the pack, in turn. You will see [1CL] at upper right, and a voltage displayed below, to three decimal places; for example: 3.982.
*Press
ENTER
to make the [1CL] flash, and
UP
to see the voltage for the second cell, third cell, etc…
*When you have seen the voltage for the last cell in the pack, press
DOWN
to reach the next screen:
AVG. V
shows the
average
voltage per cell, across the whole pack.
V. GAP
shows the
difference
between the highest and lowest volt cells in the pack
*Press the
DOWN
button to reach the next screen, showing voltage for every cell in the pack to two decimal places (e.g. 3.98).
Press
ENTER
for two seconds. You will see
BALANCE START / SOLO MODE
- SYNC MODE
---
If you are
using a single charger only. Use UP or DOWN to select SOLO MODE.
Hold down the
ENTER
button, the
charger will check the battery, and then ask you to confirm the number of cells in the pack. If correct, press ENTER once to start
balance charging.
---
If you are using two NET chargers
, and want to balance two packs (of same type and capacity,) as a single unit – such
as 4S VX3700 and 5S VX3700 to make a 9S series-connected flight pack –hold down the
ENTER
and
DOWN
key to change from
SOLO MODE to SYNC MODE. Hold down the
ENTER
to start
BATTERY CHECK
. The number of cells in each pack will be shown
one above the other. If both are correct, press
ENTER
to begin balancing.
After Balancing has begun, you may return (using UP or DOWN keys) to the screen which shows all cell voltages together. Cells
which are
higher
in voltage will show the decimal point alternating to a larger square shape, indicating that these cells are being
discharged, while the lower voltage cells are not. Hold down the
ENTER
to stop balancing at any time.
NOTE!!
SYNC MODE Charging (selected in similar way to SYNC BALANCING above) is intended to be used only with two packs of
the same brand, capacity, type, and lifecycle history! For example, two packs of LVX5000 4S lithium polymer purchased at the
same time and used together as a 8S flight pack in series when flying a particular model. At the start of SYNC MODE charging,
both packs should be at roughly the same discharge state. Otherwise, you should SOLO MODE charge each pack separately, and
when both are done use SYNC MODE balancing before connecting in series for flight.
---- USER SETUP
(these settings are “sticky” until you change them again)
Press the
MODE
button until you reach the
USER SETUP
- TEMP MODE screen.
* Press
ENTER
and use
UP
or
DOWN
keys to select temperature display in degrees Fahrenheit or Celsius
Press
DOWN
to scroll through the following screens, and
ENTER
then
UP
or
DOWN
to change settings on each screen:
*
BUTTON SOUND
screen - ON or OFF
*
FINISH SOUND TIME
screen - OFF, ON (continuous), 1 Minute, 15 Seconds, 5 Seconds
*
FINISH SOUND MELODY
screen – Choices 1 to 10 (Will also play each Melody)
*
POWER SUPPLY VOLTAGE
screen – Set to limit max WATTS INPUT (typically for variable voltage PS units only)
*
POWER SUPPLY CURRENT
screen – Set at the rated CURRENT (A) of your power source [set to 40A if car battery]
Power Supply Voltage and Current together comprise PS Load Control. The EOS0720iNET is an extremely powerful charger, and
can – particularly when charging high-voltage packs at high rate settings - pull more amperage than many power supplies can
deliver. To avoid stressing your PS and having charges terminated prematurely, you can tell the charger the rating of your
supply, to limit the load on the supply. If you find the PS is still overloaded, reduce the setting for POWER
SUPPLY CURRENT
until
the problem goes away (or buy a stronger Power Supply unit!).
* You have a fixed Voltage AC/DC PS with 20A rating: Set
PS CURRENT
to 20A (or less).
* You have an AC/DC PS with variable voltage from 12V-18V, and 300W limit: Set your PS to 18V, set
PS VOLTAGE
to 18, set
PS CURRENT
to 300W/18= ~16A.
BATTERY CHARGING - EXTENDED DETAIL
Consult the documentation or labels provided with your battery to determine the correct capacity setting. It is very important to
get this right, as the charger uses the capacity setting to determine nominal charge rate (amperage), TCS percentage, and
safety termination. Incorrect settings could damage the battery, and could even cause an accident.
-----
For Lithium types CAPACITY is selected in mAh
. Selection is in increments of 100mAh.
CURRENT
is set in Ampere (at
CHG CURRENT
screen), so divide mAh by 1000 to get Amperage. For 700mAh, current is 0.7A for 1C, up to 1.4A for 2C max.
For 1800mAh, 1.8A for 1C, and 3.6A for 2C and so on. All Hyperion LiPo packs are rated for safe 2C charging. Hyperion does not
support nor recommend ever charging Lithium Polymer at rates higher than 2C.
-----
Lithium Polymer (3.7v) vs. Lithium Ion
(3.6v)
Please make absolutely sure that you properly identify the type of
lithium battery you are charging, the capacity in mAh, and the number of cells wired in series and the pack voltage! Lithium Ion
(3.6v nominal) should never exceed 1C charge rate.
Never
charge
Li Ion 3.6V
types by LIPO 3.7V charger mode!
----- A123 / LiFePO4 Cells:
The A123/LiFePO4 charge/discharge modes are intended for cells with 3.3V nominal produced by
A123 Company, or other-brand LiFePO4 cells which are recognized to be of good quality from well-known makers. In
MEMORY
MODE
, choose A123 for
BATT TYPE,
for charging such cells. The A123 charge mode MAY work with “no-name brand” LiFePO4
cells having 3.3V nominal voltage, but Hyperion has found some “knock off” cells in the market of very questionable quality.
Customers who use A123 mode (LiFePO4 mode) to charge such off-brand cells assume all risk.
