Wow! I'm actually picking up a lot from you guys answers. Thank you very much guys! And oh im pretty aware with battery limit, i know my build is low but im using dual 18650 parallel box mod and yes if i was using a single battery then i would be above samsung's max amp limit, its 20A for the 25R's. Am i wrong for thinking parallel doubles the mAh and amp while series doubles the volts and amp limit and mAh is still the same?
