The BT-C3100 V2.2 professional charger is an analysis Li-Ion and NiMH charger. The charger can both charge and discharge, thus bridging the gap between the simple, universal Li-Ion, NiMH chargers and the much more complex and feature-rich “model chargers”.
The following Li-Ion, NIMH and NiCd battery types can be charged:
Li-Ion: 10440 / 16340 / 14500 / 14650 / 16650 / 18350 / 17500 / 17670 / 18500 / 18650 / 18700 / 26500 / 26650 / 22650 / 20700 / 20700 21700*, 3.6V and 3.7V Li-Ion batteries.
Ni-MH/Ni-CD: AA, AAA, A, SC, C (SC and C only with flat positive terminal)
Please note: 20700 and 21700 batteries only as unprotected version up to max. length of 71mm. Protected 20700 and 21700 with excess length will not fit.
Opus BT-C3100 V2.2 charger Features:
1.The charging current can be selected for200mA, 300mA,500mA,700mA and 1000mA. Default discharging current is 500mA.
2.It provides four independent charging slots for rechargeable batteries. The charger can charge batteries of different type and size and with different capacity at the same time
3.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.
4. The charger also includes overheat detection to protect rechargeable batteries and charger itself from overheating.
5. New added quick test mode to test the battery impedance.
6. Four Working Mode Available at User’s Choice: Charge, Discharge, Test,Quick Test and Refresh.
7. Easy Read LCD with back light Showing Battery Voltage, Charge/Discharge Current, Charging Time, Battery Capacity etc.
