This is great if you need to test LiFeP04 chemistry. The other testers don't do 3.2v cells.

Opus BT C3100 V2.2 Digital Intelligent 4 Slot LCD Battery Charger Compatible with Li-ion NiCd NiMh LiFeP04 Batteries

  • Plug: US adapter,Charging Cell Type: Ni-MH, NiCd, Lithium Ion,Designed for AA ( LR6 ) and AAA ( LR3 NiCd, NiMH or 3.7V Li-ion rechargeable batteries in size type of 10440, 14500, 16340, 17335, 17500, 18490, 17670, 18650
  • Note: Battery not included,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
  • Four Working Mode Available at User's Choice: Charge, Discharge, Test, Quick Test and Refresh,The charger also includes overheat detection to protect rechargeable batteries and charger itself from overheating
  • 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.


Main Features:
The charger integrates the minus delta voltage 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 ). 
Easy to read LCD with back light Showing Battery Voltage, Charge / Discharge Current, Charging Time, Battery Capacity etc.

Operating temperature: 0 - 40 deg.C

Max charging capacity: Up to 20000mAh
Power adapter: DC 12V, 3.0A ( Output ), 100 - 240V, 50 / 60Hz ( Input )

1.  Voltage update rate is 30s instead of 60s.
2.  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
3.  35V charging algorithm is changed to 4.27V.
4.  New fan cover make better protection for cooling fan.
5.  Charging current range ( mA ): 200, 300, 500, 700, 1000, 1500, 2000
6.  Discharge current range ( mA ):200, 300, 500, 700, 1000 ( li-ion cell battery only )
7.  Max. charging capacity: 20000mAh
8.  Voltage deviation: max 0.03V 4.2V
9.  Current deviation: max 5%
