how much juice to charge with?

I have an OPUS 3100 v2.1 and I want to know the correct current setting for various functions of various battery sizes.

0.5C is typically the “correct” setting for charging cylindrical LiCo. C rates are based on capacity, so for 2800mAh 1C is 2.8A, 0.5C is 1.4A. I think most cells will specify 1C as a “fast charge.”

thank you. I read all this stuff and then can’t find it again. Sometimes it doesn’t sink in!

I read the stuff at battery university and I thought I got this, but I’m second guessing myself eve on basic stuff. I’m trying to understand it rather than just do what the instructions say to do.
