Using the EOS 5i DP AC/DC
The EOS 5i includes an Output Harness with two 4mm male “banana” connectors attached. First, solder your chosen battery
connector to the bare wire ends of the harness, taking great care to observe proper polarity.
ALWAYS FOLLOW this connection sequence, and reverse sequence to disconnect:
1) Connect OUTPUT harness to the sockets located on the right side of the charger.
Take care that the Output Harness RED wire bullet connector goes to the (+) socket, and BLACK wire to (-) .
2a) Connect Charger INPUT alligator clips to an appropriate DC power source:
a) A 12V automobile battery
b) A quality, low-noise DC power supply of 12~15V with 5A+ rating (large batteries may require 10A supply)
OR
2b) Connect to AC wall power 100~240V using the supplied AC adapter cable
DO NOT CONNECT BOTH AC AND DC INPUT AT THE SAME TIME!!
The Charger will display INPUT VOLTAGE error message if input voltage is out of range. If this happens, please recheck the input
power supply to make sure correct voltage is present.
3) Set the battery type using the charger configuration buttons.
*The INC and DEC buttons are used to Increase or Decrease
values, such as Charge Current or Cell Count
*The INC and DEC buttons are also used to select MODE, such as Charge, Discharge, or Cycle
*The BATT TYPE and ENTER buttons both have two modes: SHORT press or LONG (~1 second) press
•
Short press BATT TYPE: Scroll battery types
•
Long press BATT TYPE: View input/output Data
•
Short press ENTER: Scroll settings for a battery type. Values will blink when selected. If nothing is changed, blinking
will stop. Short press Enter until re-selected, then INC/DEC to change values.
•
Long press ENTER: START charging (or discharging, or cycling)
Let’s start by using a NiMh battery as an example.
When the charger is first connected to input power, it will display the previously used battery configuration. This is especially
convenient if you often charge the same type of battery.
1) If NIMH is not shown, short push the BATT TYPE button to scroll through all battery types. Stop when you reach NIMH.
2) Short press the ENTER button to select “C”, charge rate in Ampere
3) Press INC or DEC buttons to choose the proper rate for your battery pack.
Charging NiCd and NiMH is mostly automatic, and the setup routines are the same for both. You only need to consult the
documentation for your battery pack (or ask your dealer) to determine the proper charge current in Ampere (A). If the rate is given
in mA, note that 100mA equals 0.1A: so 900mA would be 0.9A, for example.
4) Attach your NiMH battery to the EOS 5i Output side harness, checking that +/- polarity is correct.
5) Long press ENTER button (hold down for about 1 second) to begin charging
NO BATTERY error - if battery not connected
OPEN CIRCUIT error - if the battery becomes disconnected from the charger after START
REVERSE POLARITY error - if the battery is connected in reverse
DATA RANGE OVER ERROR - EOSLBA10 Balancer and EOS5i Charger Battery Type Settings are not the same
In our NiMH charging example above, we pressed the ENTER button when “NiMH” was blinking, to go directly to charge rate
setting. However, if you want to enter DISCHARGE or CYCLE modes, you can press the BATT TYPE button to start NiMH
blinking, then press INC/DEC buttons to scroll through the various modes. Once the mode is settled (like CYCLE), short
press ENTER to start values blinking for editing.
Below are the flow charts for all the settings in the charger for each battery type
A123 MODE
The A123 charge/discharge modes are intended for cells with 3.3V nominal, produced by A123 Company ONLY!
While the EOS5i A123 charge mode MAY work with other lithium cells having 3.3V nominal voltage, Hyperion strictly cautions
against charging other-brand cells with EOS 5i A123 routine. Customers who use A123 mode to charge other-brand
cells assume all risk.
Due to the nature of A123 cells, one MUST ALWAYS use a cell balancer when using A123 Mode. The original Hyperion
EOSLBA10 can be used, but was originally designed for Lithium Polymer batteries. The EOSLBA10 Balancer function works
well with A123, but the overcharge and discharge protection voltages are higher than optimal for A123. Note also that if
original LBA10 (w/o A123 mode) is used, connecting LBA10 to EOS5i via DataPort Cable will result in the DATA RANGE OVER
error warning. For best results, EOSLBA10-A (with LIPO and A123 modes) should be used; when in A123 mode, version
EOSLBA10-A provides correct protection voltages for A123 cells - both for over-charge and over-discharge conditions.
EOSLBA10-A should be connected to EOS Charger via DataPort Cable (#HP- EOSLBA10-DPC).
To help distinguish between Lithium Polymer and A123 Modes, the screen for A123 CELL COUNT lists pack voltages, rather
than “S” count as in LIPO mode. Use the chart below if your pack does not list voltage.
