5 of 5 Opus BT-C3100 Rocks!! September 4, 2020
Reviewer: Chris from SAINT JOHN, NB Canada  
Pretty good device. It's currently restoring all my salvaged 18650 cells for my ebike battery. It's easy to use and delivery was pretty quick too. I definitely recommend this product. I would advice anyone who is in a rush to "restore" a lot of old cells to buy multiple units as it can take a long time.

5 of 5 Great Charger! September 3, 2020
Reviewer: Rebecca Martin from Fremont, CA United States  
I especially like that it can accurately measure internal resistance and cell capacity, making it easy to sort out those batteries that are due for recycling.

4 of 5 My first modern battery charger August 27, 2020
Reviewer: Steve from Blacksburg, VA United States  
After watching a lot of YouTube videos I chose the Opus BT-C3100 v2.2 charger to replace my very old NiMh/NiCad charger.  The Opus BT-C3100 had great reviews although I am still a little confused by the mixed messaging regarding similarities with the BT-C3400 v2.2.  The prices were different but some sites suggested that the C3100 and the C3400 were identical.  I cannot really compare the BT-C3100 against any other modern battery charger since this is my first purchase but I really like the ability to test batteries and to refresh them.  The Refresh/Discharge mode can take a very long time (more than 1 day) to complete but that could be because of the age of some of my rechargeables.  The only negative I have is that the cooling fan can be very noisy and does not like to be moved while running.  I like this universal charger a lot and I plan to purchase more as presents.
