1. Operating mode settings

The charger supports 4 different battery chemistries: LiPo, LiHV, LiFe and NiMH The charger supports 4 different modes:

CHARGE=Balance Charge    CellBAL = Cell balancing
STORAGE= Storage              DISCHG = Discharge

Remarks:
The balance charge mode is a synchronized charging and balancing process. In this mode, a battery will be balanced and charged to a preset cutoff voltage.

The Cell Balancing mode of this charger is used to equalize voltage difference of a multiple cell battery. In this mode, if the voltage is lower than 4.05V per cell of a LiPo battery, or 3.35V of a LiFe battery, the charger will balance the cell voltage and charge the battery to 4.05V(Lipo) and 3.35V(LiFe). Otherwise, If the voltage is over than 4.05V per cell of a LiPo battery, or 3.35V of a LiFe battery,the charger will enter balance the cells only without charging to be full.

COMMON ERRORS AND SOLUTIONS

NO

| Error status| LED display| Reason of Error|

Solution

1

| Balance port error 1| | Cell count is set incorrectly|

1. Click the button of Back /Stop to exit the error status.
2. Check the cell count setting and be certain it is correct for battery being charged.

2

| Balance port error 2| | Cell count is set incorrectly
The charger detected the single cell voltage is below 0.6V through the balance port.|

1. Click the button of Back /Stop to exit the error status.
2. Check the cell count setting and be certain it is correct for battery being charged.
3. If the setting parameter is consistent with the actual one, the abnormality still occurs. Use the charger “PROGRAM SELECT LI BATT METER” to read the voltage of each cell and check it.
   Check the balancing cables for poor contact or breakage

3

| Over voltage protection of main port in charger interface| | The battery voltage exceeded the Max charging voltage of charger. The definition is showed as below:
Lipo:4.5 Number of series /LiHV :4.6 Number of series
LiFe:4.0s Number of series /NiMH: 1.8 Number of series
(Wrong battery type or over voltage) |

1. Click the button of Back /Stop to exit the error status.
2. Check he setting series and actual series, if not match, revise setting series and actual series consistently.
3. If you had set the charger and actual series consistently, charger still shows the error. Use the charger function”PROGRAM SELECT LI BATT METER” to read every cell’s voltage. If the total voltage has exceeded the setting standard, please to discharge the battery voltage standard or below.

4

| Over voltage protection in balance port of charger| | The voltage of single cell exceeds the max setting voltage.
Setting standard as below:
LIPO:4.5V/LIHV:4.6V
LIFE:4.0V/NIMH:1.8V|

1. Click the button of Back /Stop to exit the error status.
2. Use the charger function”PROGRAM SELECT LI BATT METER” to read every cell ‘s voltage. To discharge the voltage of single cell or the total voltage of whole battery, until the voltage of single cell is below the setting standard.

5

| Battery interface no Loading/low voltage/short circuit protection| | -Battery interface (main port) no Loading
-Battery interface (main port) low voltage(≤2.5V)
-Battery interface (main port) short circuit protection|

1. Click the button of Back /Stop to exit the error status.

2. Check the battery interface port is without loading: check the if there is poor contact in the charger interface with battery

3. Check whether the battery is over discharge,(the total voltage ≤2.5V). Use the charger function “PROGRAM SELECT LI BATT METER” to read every cell ‘s voltage. If the total voltage is lower than 2.5V, it is over discharge and suggest to charge before use.
   3.Check whether the battery is short circuit. Pull out the battery, and use the multimeter to test the battery, checking whether it is short circuit. If yes, please do not use the battery.

4. If you have check the 2/3/4, and the error is not solved，please contact the professional for checking and maintaining.

6

| Can not work| | circuit failure| Please unplug the AC plug for 30 second before inserting.

7

| Battery Voltage Error| | When the charger detected that the cell voltage difference meet the following conditions, it will trigger a battery voltage abnormal alarm:
LiPo/LiHV: Single cell voltage <2.8V, voltage difference △V>400mV;
LiFe: Single cell voltage <1.0V, voltage difference △V>500mV;|

1. Select “PROGRAM SELECT→ LI BATT METER” to read the voltage of a single cell. If the voltage meets the abnormal trigger condition, it means that the battery is faulty (the voltage is too low or the voltage difference is too large). It is recommended to stop using the battery and discard it;
2. If the displayed voltage of “PROGRAM SELECT→ LI BATT METER” does not match the actual battery voltage, check the balance port line against the voltage to see if there is a bad contact or break.
