User’s Manual for 1210I-A with A123 Mode

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.

(for A123 cells, ALWAYS use balancer)

•

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 automobile battery - 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.

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,

A123,

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

are best

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

polymer

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.

For

all battery types

CAPACITY is given in mAh

(at BATTERY SETUP screen). Selection is in increments of 100mAh. If your

battery does not fall on an exact division of 100 - for example

your

battery is rated 670mAh - you should choose the next

higher

setting. In our example, 700mAh would be appropriate.

CURRENT

is set in Ampere (at CHARGE MODE 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

(1C)

~3.6A

(2C)

and

so on….

Lithium

Polymer/Ion

:

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 lithium

Polymer/Ion

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:

A123 Brand Cells:

The A123 charge/discharge modes are intended for cells with 3.3V nominal produced by A123

Company

ONLY! While the EOS1210i A123 charge mode MAY work with other lithium cells having 3.3V nominal voltage,

Hyperion strictly cautions against charging other-brand cells with EOS 1210i A123 routine.

Customers who use A123 mode

to charge other-brand cells assume all risk.

Due to the nature of A123 cells and the very high rates at which they can be charged, one

MUST ALWAYS use a cell balancer
