 Opus BT - C3100 V2.2 Digital Intelligent 4 Slots LCD Battery Charger for Li-ion NiCd NiMh Batteries

This charger is an analyzing charger for LiIon and NiMH batteries, which means the charger can charge and discharge while measuring.

Opus BT - C3100 V2.2 Digital Intelligent 4 Slots LCD Battery Charger for Li-ion NiCd NiMh Batteries 

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:

  • CHARGE: Charge battery with 200 to 1000 (2000) mA.
  • DISCHARGE: Discharge battery with 200 to 1000 mA.
  • DISCHARGE REFRESH: Discharge and charge the battery 3 times.
  • CHARGE TEST: Charge, discharge and charge the battery, show how much current was discharged.
  • QUICK TEST: Measure the internal resistance of the battery.


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.

Here is an example where I have selected different functions for each slot.

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 32mm to 72.5mm.
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: 200mA, 300mA, 500mA, 700mA, 1000mA, 1500mA, 2000mA

Discharge currents: 200mA, 300mA, 500mA, 700mA, 1000mA

The charger can easily handle 
70mm long batteries.
It is recommended to charge smaller batteries in the two center slots.
The charger has an internal switch marked with 3.7V, 4.20V and 4.35V. I have not tested this switch, because it is internal, but it might be possible to charge other Li-ion chemistries.
