Package Contents:

  • OPUS BT-C3100 v2.2 digital battery charger
  • Standard US power plug
  • User Manual

Features:

  • 4 independent channels. Most chargers have some channels connected together but not this one. You can have each channel doing a different thing, one could be analyzing while another is charging, they could all be charging at different rates, the sky is the limit.
  • Internal resistance quick battery test mode checks internal resistance of batteries
  • Discharge testing up to 1A checks that your batteries really have as many mAh as they say they do.
  • Charging up to 2A per channel (up to 2 batteries) or 1A per channel (up to 4 batteries) allows very fast battery charging.
  • Refresh mode allows you to cycle batteries automatically
  • Charges Li-ion, NiMH, and NiCd
  • Can be set to 3.7V LiFeO4 charging or 4.35V high voltage li-ion charging by a switch on the PCB. Default li-ion charging mode is 4.2V CC/CV.
  • Minus delta voltage charging for NiCd/NiMH reliable charging.
  • New backlit LED display tells you information

Best charger I have found. July 12, 2018
Reviewer: Bill from Yadkinville, NC United States  
I already had an Opus BT-C700 for Nicads & NiMhs & needed one for lithium 18650s. After researching what is available, I ordered the BT-C3100 V2.2. It works great! I like being able to monitor all the parameters such as voltage, charge or discharge current, MaHrs put it, etc. The voltage reading is a little low but the cutoff point seems to be 4.2V like it should be.
