I'm going to have the Nitecore i4 v2 coming in the mail today. I went back to the page where I bought it to see how fast it charged. I found that there were 3 charging modes. CC, CV, and Trickle Charge. I can sort of guess what trickle charge is, but what mode is the FASTEST for me to charge my 18650's at? I have 2 shitty 1600mAh Sony VCT3's until I get my smurfs and my purple efest's later and it's going to be a day before I get the smurfs, and a whole month before the efests come in. On my sig at 0.3 ohm twisted 26 gauge builds, they tend to last me a very short amount of time because they are only 1600mAh. I just want to know the fastest and safest mode to charge them at. Thanks for any help in advance!
