i have two 18650 batteries of this type (but with one 1500mAh and one 2000mAh) and i need to charge them with two (or more if needed) 6v 1A solar panels. I was looking around and found this but this one is 4.2v instead of 3.7, and i'm reading mixed things about if this would work

4.2V voltage at 100% charge is good for 3.7 Li ion battery, but they must be the same type, age, same batch. You can't pick up batteries whatever comes in yopur hand.
