the top line (starting with #1 on the left and ending with #4 on the right) and 5-8 on the bottom line.  
Also, any cells that show 0.00V are not applicable or are not being measured due to a balance 
connector connection issue.  So if you’ve connected a 4S battery but see voltages for only 3 cells be 
sure to check the connections accordingly. 
 

Also, in some cases the voltage for cell #1 will not show correctly in relation to the rest of the 
cells in the battery if only the balance connector is connected to the balancer/charger.  If you 
encounter this issue, keep the balance connector connected then also connect the main power 
leads to the charger.  Then, use the +/– buttons to scroll away from and back to the individual 
cell voltage data screen to refresh the measurement.

  Now the voltage for cell #1 should also 

show correctly. 
 

Please also note that while only the second (hundredths) place after the decimal is shown due 
to the space available on the screen (in order to show voltages for up to 8 cells on a single 
screen), the charger is measuring and calculating the voltages/balance by using to the third 
(thousandths) place.  This means when you see a cell at 3.80V and another at 3.82V the cells 
are likely as close as 3.804V and 3.816V but the values on the screen are being rounded up 
and down accordingly. 

 

Real-Time Input Voltage and Output Voltage Data 

 
This is the real-time input and output voltage (per the selected port) data.  You can see the voltage 
from the input power source as well as the voltage at the output if any battery is connected to the 
charger leads.  This is particularly helpful if you’d like to determine the voltage of the battery that is 
connected without starting a charge/discharge process. 
 
Please also note that while only the second (hundredths) place after the decimal is shown the charger 
is measuring the input/output voltage by using to the third (thousandths) place.  This means the 
input/output voltage reading may appear to move up and down slightly, however, the input/output 
voltage is indeed stable. 
 

Internal Temperature Data 

 
The Internal TEMP data displays the internal temperature of the charger.  This can be particularly 
helpful if the other port is in use so you can see if the charger’s temperature is approaching the 
Temperature Cutoff even before starting a charge/discharge process on the currently inactive port. 
 

ERROR MESSAGES AND TROUBLESHOOTING 
 

In some cases you may encounter the following error messages: 

 
 

 

 

 
 
 
 
 
 
 
 
 

 

 

This error message indicates that the 
voltage from the input power source/supply 
is too low (below 10.0V). 

 

 

This error message indicates that the 
voltage from the input power source/supply 
is too high (above 28.0V).
