Hyperion EOS 1210i Charger

User’s Manual

Warnings:

The EOS 1210i is a carefully-designed charger with many built-in
safety features, such as reverse polarity protection, input voltage
error warning, and cell-count mismatch warnings for lithium
chemistry batteries. HOWEVER, IT IS THE RESPOSIBILITY OF THE
USER TO INSURE THAT THE CHARGER IS CONFIGURED AND USED IN
A SAFE MANNER IN PROPER ENVIRONMENT. Note that as cell count
of lithium batteries becomes higher, all warning systems become less
accurate. As such, we strongly recommend the use of Hyperion
LBA10 balancers when charging lithium batteries, and especially so at
4S or higher. LBA provide much additional safety, because the LBA
monitors each individual cell.

• Always be sure that the charger is properly configured for
the correct battery type.

• Be sure that the batteries you charge are capable of charge
at the rate you select.

• Never charge batteries unattended.

• Charge only in a fire-resistant environment, such as on

concrete or brick, rather than wood surfaces.

• Do not charge near easily flammable materials.

• Do not charge batteries inside a model.

• Charging outdoors is recommended whenever practical

• Use only high-quality gold 4mm bullet connectors for charge

output cable connection to the charger. See “setup”.

• Insulate all Output connectors to eliminate the possibility of
short circuit. Damage caused by output short circuit is not
covered by warranty.

• Do not drop or cause other shock to the charger, nor subject
it to moisture or water

• Do not attempt to charge battery packs made from different
types of cells, a mixture of old and new cells, or cells made
with chemistry not supported by the EOS 1210i

• Do not attempt to charge “non-rechargeable” dry cells.

• Do not open the case of the charger under any

circumstances. Doing so will void the warranty.

• Keep the charger away from children or pets at all times.

In the event of injury of any kind, seek the attention of

medical professionals immediately.

General Setup:

The EOS 1210i comes with male 4mm Bullet connectors
(also known as ‘banana connectors’) attached to the
power INPUT cables. These cables are appropriate for
attaching directly to most high-quality AC-DC 12V
power supply units, such as the BK Precision (USA)
model 1692. Also included are large Terminal Clips with
matching 4mm female bullet connectors, for attaching
directly to 12V lead-acid batteries.

Output side connector/cable assembly is also supplied.
Carefully solder your preferred battery connector to the
free ends. If you make up additional output cables,
note that MINIMUM inner cable diameter should be

2.5mm (14ga) and MAXIMUM cable length is 20cm (8”).
It is critically important that you use either a fully

charged 12V lead-acid battery of adequate capacity - or
a high quality AC-DC power supply in the range of 12V
to 15V DC output, with minimum current rating of 8A.
When charging high voltage batteries at high current an
output rating of up to 25A may be required.

If you have any trouble charging after confirming that
input and output cables are properly connected and of
the proper materials, be sure to check the charger on
an automotive battery. Many problems are associated
with poor quality or inadequate switching AC-DC power
supplies.

If, after carefully reading the following pages on usage,
you have any difficulty using the charger please refer to
the final pages for troubleshooting guide and warranty
terms. It is well to carefully check your charger before
making a return, as problems in setup, cabling, or
power supply are much more common than defects in
the charger. Chargers returned by the user and later
found not defective will only be returned to the user at
the user’s expense.

Memory Position and Settings per Battery Type

The “Auto” modes for NiCd and NiMh battery types are preferred whenever you have a battery pack made from
quality cells and in good condition and balance. The EOS 1210i charges NiCd and NiMH in Auto Mode based on an
intelligent algorithm which maximizes performance and minimizes charge time.

These two pre-configured memory positions cannot be edited:

A1 - NiCd Automatic
A2- NiMH Automatic

Ten additional memory positions - M0 to M9 - allow you to choose parameters for charging or discharging, such as
battery type (NiMH, NiCd, LiPo, Lead-Acid), battery capacity, discharge rate, cutoff voltage or temperature, and
more.

Charging - Let’s try it once to learn it….

ENTER: Select Memory Position to change / Charge Start, Charge Stop
SETUP: Selects parameters for editing in turn
UP/DOWN: Scroll through memory positions / Change parameter settings

After connecting the charger to a suitable power source, the LCD monitor will show the
configuration used in the previous charging session.

After the welcome screen, press ENTER then the UP button to scroll through the pre-set memory positions. Stop
on M8 (NiCd 24 cell). Press ENTER to choose Memory slot M8. Now press SETUP, and you will see that the text
for battery type is blinking (“NiCd”), and screen title has changed to BATTERY SETUP. Press the UP (or DOWN)
button to scroll through battery type selections. Press SETUP again at LiPo to set the battery type to Lithium
Polymer; the cursor then moves to Voltage Selection. For lithium polymer, voltages are listed as number of cells in
series, or “S”. Press the UP key to choose “4S”, then press SETUP again. Press DOWN repeatedly to set Battery
Capacity to 2500 (mAh), then press SETUP. The display changes from BATTERY SETUP back to MEMORY SELECT.
Now, press the DOWN button to move away from MEMORY SELECT screen, and go to CHARGE MODE screen.

Note that CHARGE RATE (C:) will be 2.5A to start. This is default behavior, and is a “One C” charge rate based on
the 2500mAh capacity you set earlier, at the BATTERY SETUP screen. Now keep pressing the UP key, until the
Charge Rate display stops changing. You will see that it allows you to set up to 5A charge rate maximum, which is
“2C” for our 2500mAh battery example. Note: Hyperion batteries all support charge rates of 2C+. But do check
that your battery brand is capable of charge in excess of 1C before making such selections. See Addendum later
as to why rates higher than 2C should be avoided.

Now, press SETUP again, to select estimated Terminal Capacity of Charge. Press the DOWN key, until the display
shows 90%, then press SETUP. Note: normally this setting is 100%, but we have altered it just to see how it is
done, for training purposes. (see notes on TCS later in Addendum)

At this point, you have altered memory slot #8 to charge 4S 2500mAh LiPo batteries at 2C rate, to 90% of battery
capacity. We should still be at the CHARGE MODE screen. You should not have anything connected to the output
port at this time. Now, we are going to press the ENTER key to start “charging”, but will get a CONNECT ERROR
from the charger; that’s ok, but do be ready to press ENTER again to stop the Warning buzzer. So press ENTER
now, then ENTER again after the warning tones. Finished testing? Ok, now you know how to configure your new
EOS 1210i, to charge a lithium battery pack!

More About BATTERY SETUP and CHARGE MODE Screens

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.

Lithium: Please be absolutely sure that you know the type of lithium battery you are charging, the
capacity in mAh, and the number of cells wired in series! The EOS charger is only for lithiu m with 3.7V
per cell nominal. If your battery does not have a number for “S” count on the label, like “3S”, but does
show the nominal voltage, use the chart below to set the correct “S” when charging:
