user43433: So, i am about to buy a brushless motor a ESC and a 18650 batteries for my arduino.
The batteries "specs" is 3.7v and 20a, if i would to put 2 and more in parallel would i get 7.4v 20a or 7.4v 40a?
Thanks.

user2881: In parallel you'd get 3.7V 40A
What I think you mean is in series. That way you get 7.4V 20A.
