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.

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.
