Glad you like the charger , we really do a lot for it ,and I like it so much

Our batteries are all lithium ones. Different capacity for different size differs from others. You know , like , 18650 2500mAh is IMR , 26650 3000mAh is ICR , ect.
Each one needs different material to get its best performance.
We are new so there are not too much spec about so far , this is the beginning . If you have any advise , so glad.
