HITEC X2-400: DC/DC Dual Port Charger - Manual (Page 18)

This screen, you can set up the current and voltage of the
battery pack. Charging and discharging will bring the batter-
ies to the storage level.
This screen shows the real-time status of the charge or
discharge process. Press the BATT TYPE/STOP key once to
stop the charging process.
NOTE
During the discharge process the X2-400’s Microprocessor monitors the voltage of each
cell during the Storage Mode or Discharge process. If the voltage of any cell is abnormal,
the charger will display an error message and immediately terminate the program.
Before disconnecting the battery review the error message then press the INC button to
display which cell is.
Charging Lithium Batteries in the Storage Mode
The Storage Mode function is for charging/discharging batteries that will not be used
immediately or that will be stored for a period of time. The program is designed for charg-
ing or discharging batteries to a specific voltage level depending on the type of battery
(Li-ion = 3.75V, LiPo = 3.85V and LiFe = 3.3V) The program will begin to discharge if the
original state of the battery exceeds the voltage level for storage.
WARNING: Lithium batteries cannot be discharged to a voltage lower than the minimum
voltage for the cell type. Doing so will result in a rapid loss of capacity and/or total failure.
While the X2-400 monitors each individual cell during the discharge process the discharg-
ing cutoff is based on the total pack voltage therefore it is important to watch the discharge
process closely to make sure a cell does not fall below the minimum voltage. Generally,
lithium batteries don’t need to be discharged and it is not recommended that you discharge
them. If you do choose to discharge your lithium batteries it is recommended that you cycle
them using use Storage Mode charging to cycle the batteries.
Error Message Display
This screen shows that the processor detected the voltage of
one on the cells is too low.
This screen shows the 4th cell was damaged. If the cell is
disconnected or not present the reading of the voltage will be
zero.
