[ Main Features ]: 
This charger is the most advanced single cell charger, you can do everything the larger Opus (C3100/C3400) can and then some. The high charge current pulses has been mostly addressed in this charger, it do still use pwm, but not always at full current (good).

High Compatibility
Li-ion: 3.7V and 3.85V batteries (with size from 10440 to 32650)NiMH / NiCd: AA, AAA, C, DLiFeO4

2.1A USB Output
● Only for Li-ion batteries
● Output mode is automatically selected according to the device attached
● Output parameters are measured and displayed on LCD

Working Mode
4 working modes for Li-ion: Charge, discharge, test and impedance test 
5 working modes for NiMH: Charge, discharge, test, refresh and impedance test
● Discharging current can be selected from 100mA to 1000mA 
● For Li-ion batteries, if charging current is over 1000mA, its CV charging terminate current is 100mA. If charging current is less than 1000mA, its CV terminate current is 50mA
● 0dv and –dv is automatically selected according to NiMH battery status to ensure battery is fully charged

Over heat protection
When temperature is over 60 degree centigrade, working current will be reduced until the condition is improved. If temperature is up to 75 degree centigrade, charger will shut down working process until temperature is lower than the safe limit


Parameter:
Input: AC 100-240V

Output: 12V / 1A
USB output: 5.0V 2.1A

BT-C900 - Only Intelligent Charger for 9V Batteries
Opus BT-C900 is the only type intelligent charger for 9V rechargeable batteries, such as NiMH, NiCd, Li-ion from 7.2V to 9.6V with LCD display. BT-C900 charger handles 4 batteries at the same time with each battery independent from working mode or display content at the same time. Different working modes are under user choice: charge, discharge, test, refresh, and quick test (for internal resistant measurement). Charging current is programmable from 50mA to 200mA with 25mA per increment step. Discharging current is automatically set to the same as selected charging current.

[ Main Features ]

• It is the only type intelligent charger for 9V rechargeable batteries
• Battery related information can be displayed on LCD for each slot respectively: V, mA, mAh, h:mm (time) and IR (unit in milli ohm).
• For NiMH or NiCD battery charging, -dv or 0dv termination is adopted, charger can handle 7.2V, 8.4V and 9.6V type batteries.
• The charger also includes overheat detection to protect rechargeable batteries and charger itself from overheating
• Operating temperature: 0 - 40 deg.C
• Power adapter: DC 12V, 1.5A (output), 100-240V, 50/60Hz (input) 

Opus BT - C3100 V2.2 Li - ion Digital NiCd NiMH Battery Charger

Price: $36.97

[ Main Features ]

● NEW LED back light displays charging / discharging / quick test / circuit more clearly in the dark

● New refresh mode can show you batteries capacity, letting you know real magnitude

● The charging current can be selected to be 200mA, 300mA, 500mA, 700mA or 1000mA (1500mA and 2000mA can only be applied when only slot 1 or 4 is selected). Default discharging current is 500mA

● It provides four independent charging slots for rechargeable batteries. The charger can charge batteries of different types and sizes and with different capacities at the same time

● The charger integrates the minus delta voltage ( -ΔV ) for NiCd or NiMh battery charging termination, and for Li-ion batteries charging to 4.2V with pre-selected constant current. ( 3.7 Li-FeO4 and 4.35 type high voltage batteries charging mode can be selected through switch on board )

● The charger also includes overheat detection to protect rechargeable batteries and charger itself from overheating

[ Highlight ]

1. Voltage update rate is 30s instead of 60s.

2. Charging voltage is regulated to 4.7V instead of 5.0V, thus loading on power adapter when batteries are flat is less. 5.0V charging voltage has problem in regulating the correct current level due to this over loading current on power adapter, which lead to Panasonic brand Li-ion batteries showed wrong charging capacity value ( + 25 percent ). With 4.7V charging voltage, the load on power adapter is greatly reduced and thus can make all types of batteries are charged properly.

3. 4.35V charging time can be very long because charging current is regulated in entering the CV stage at 4.12V, which is same as 4.2V type. Now 4.35V charging algorithm is changed to 4.27V.

5. Better safety feature: PCB temperature was used to in controlling fan on / off only with 2.0V, now this function is enhanced so that temperature is monitored for entering thermal shutdown mode when excessive high temperature is reached. It is especially helpful when fan is not running and which can lead to plastic melt down happening.

6. New fan cover make better protection for cooling fan.

7. Charging current range ( mA ): 200, 300, 500, 700, 1000, 1500, 2000

8. Discharge current range ( mA ):200, 300, 500, 700, 1000 ( li-ion cell battery only )

9. Max. charging capacity: 20000mAh

10. Voltage deviation: ＜ 0.03V @4.2V

11. Current deviation: ＜ 5%
