How to solar charge Li-Ion batteries

So, I bought two Li-Ion batteries for the field. They are definitively smaller and much lighter. I used them last night for my scopes. Everything worked great.

Did some research and found out that they need special charge controllers as their charge profile is different. After lots of research I bought new charge controller from Morningstar. In about a week will I find out if and how much of a difference that makes...
