This charger is a analyzing LiIon and NiMH charger, this means the charger can both charge and discharge while measuring. The total number of function is large and this means the technical section in this review is very large.




When the charger is turned on, it displays test where all the text can be seen. 
When startup is finished it is possible to select mode:


When display is flashing it is possible to select mode and current.
Using the slot button it is possible to reselect a slot and change parameters for it, also when charger is working.
When putting multiple batteries in the charger at the same time, it is possible to select mode and current simultaneous for all of them (Very nice).

When charging or discharging it is possible to use the DISPLAY button to select between V, mA and mAh.
The display button can also be used when the charge/discharge is finished, but the charger will change back to FULL display rather quickly.




Each time a button is pressed, the light turns on for a 20 seconds.
The FULL and NULL message can also be seen.



The charger uses an external 12 volt power supply at 3A (see later).
It has a fan, this is necessary to handle all four channels at full power. Even with only one channel in use the fan, it start and stop very often. The fan is not very loud, but due to the starting and stopping it is very annoying.



The charger uses the classical slider construction to handle most battery sizes. The slider works smoothly and can handle sizes from 32 mm to 72.5 mm.
For measuring internal resistance the slider is not very good, it often has a HIGH connection resistance.


A couple of different NiMH batteries in the charger.



And some LiIon batteries.

Using only slot 1 and 4, the maximum charge current is 2000mA.
In all other cases the maximum charge current is 1000mA.
The maximum discharge current is always 1000mA.

Charge currents: 200, 300, 500, 700, 1000, 1500, 2000
Discharge currents: 200, 300, 500, 700, 1000
