Hey guys, just got my first true mod (Maxi Roughstack) from Madvapes. I got the AG-126 charger and two 18650 batteries. The charger didn't come with any instructions, but I suppose putting the positive end up (where the + is) is the way to go. How long does it typically take an 18650 to charge? The charger just has a single light that has been a solid red for the past three hours. I assume it will change to green when fully charged. I'm charging both batteries at the same. One battery is a 2400 mah and the other is a 3000 mah. Does the difference in the mah matter if charging both at the same time? Would it be faster to just charge one at a time? If so, I assume the 2400 mah would charge more quickly? Any help is greatly appreciated as I am very anxious to try out the Roughstack.
