This is the Opus BT-C3100 v2.2.  This is identical to the BT-C3400 that some other vendors are selling.  This is the most full featured charger we sell.  It can do all kinds of stuff in addition to just charging batteries, including testing and cycling them.  Here are some of the cool 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

Incredible charger

Love this charger! It has so many different features it took a bit to learn how to navigate/use them all. Especially, since mine did NOT come with the damn instruction manual....Still great price and fast shipping.
