The best just got better. Overlander NEW Sport 2200mAh 3s 11.1v 30C is part of our Supersport range. All Overlander Supersport 30C LiPo cells are manufactured using the "STACKING" method, unlike many of the cheaper Chinese imports which are manufactured using the "WINDING" construction, a much cheaper construction method, with very limited discharge rates (15C - 18C) but often quoted as 25 - 30C. Stacking construction is known for its longevity, and gives stronger more reliable voltage.
