 - High-power and high-performance circuit
   902 employs the circuit that has maximum output power of 200W. As a result it can charge or discharge
up to 32 cells of NiCd/NiMH and 12 series of Lithium batteries with maximum current of 9.9A. Furthermore
the cooling system is so efficient that can hold such a power without any trouble of the circuit or the
operating programs. If you need more power to discharge the battery of high voltage with high current you
can link an external discharge module (ELD150) that is sold separately to the unit.

 -  Optimized operating software
   When charging or discharging, 902 has an 'AUTO' function that set the feeding current or the cell count of
Lithium battery automatically. Especially for Lithium batteries, it can prevent the over-charging can lead to
an explosion by users fault. Every program in the unit is controlled with mutual links and communicates for
every possible error. So it introduces a maximum safety. These can be set at users option.

 - 'OUTPUT-2'
  The 'OUTPUT-2' can charge NiCd or NiMH battery up to 6 cells with 'OUTPUT-1' simultaneously. It
employs the delta-peak voltage detection method not the trickle charge and is independently operated from
'OUTPUT-1'.

 -  Accept various types of Lithium battery
   902 can accept three types of Lithium batteries - LiIo, LiPo and LiFe. They have different characteristics
by their chemistry. You can select any one of them that you are going to process before the job.

 - PWM Motor driver
  You can easily break-in or test the motor at 'OUTPUT-1' with a variable feeding voltage, and running time.
And also you can check the output power and the consumption of electric current of the motor at real time.

 - Lithium 'Fast'/'Storage' mode charge
  You can charge Lithium batteries for special purposes. 'Fast' charge reduces the charging time of Lithium
battery and 'Storage mode controls the final voltage of battery to be suit for long time storage.

 -  Monitoring the voltage of individual cell
   Unbalance of the voltage of each cell can occur in the Lithium battery pack because of consecutive
charge and discharge. Using 'Lithium balancer(PB5 or PB6)', the charger monitors the voltage of each cell
and controls the charge and discharge current to equalize the voltage. For this process the charger
communicates with the external balancer thru the temperature sensor port.
                                          

 -  Battery data store/load
   For users convenience it can store maximum 10 data of battery. You can establish the data contains
program setting of the battery to be charged or discharged continually. These data can be called out at any
time you need and executed without program setting.

 -  Cyclic charging/discharging
    Perform 1 to 5 cycles of charge>discharge or discharge>charge continually for battery refreshing and
balancing.

 -  PC based analysis using USB communication
   For technical expert, 902 offers PC based program can analysis the characteristic of the battery via
USB port. It shows a graph of voltage, current, capacity and temperature curves. It also shows the
individual voltage of each cell in the Lithium battery pack. This program can run on both outputs with single
USB link to PC. You can download the software at here.

 - Back-light LCD screen
  You can adjust the brightness of LCD display

 - Robust outer aluminum case
  High-quality aluminum case is durable and very efficient to cool out the internal heat.
