Overlander Ultrasport 3700mAh 4S 14.8v 45C LiPo Battery


3700mAh 4S 14.8v 45C LiPo Battery - Overlander Ultrasport

Fully compliant LiPo batteries, choice of champions and record breakers!

The best just got better. Overlander NEW Ultrasport 3700mAh 4s 14.8v 45C is part of our brand new Ultrasport range, giving fantastic performance at a reasonable price!

All Overlander Ultrasport 45C 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.

This Ultrasport pack has:

  1. 3700 mAh
  2. 4 LiPo Cells
  3. 45C constant discharge

All pack cells are fully matched 3 ways before assembly
