Best - Performance: 50C - 60C/ 120C Motivation Power without end. This embodies the Best -Performance LiPos from Swaytronic . Technology and performance In addition to the already high quality features of the ECO line, two new processes have been integrated into the production of the Best -Performance line. Swaytronic -Cell-Match: When assembling the battery packs, it is checked that only cells with identical internal resistances are assembled. YOUR ADVANTAGE: The performance of a LiPo battery is only as strong as its weakest link. Thus, if a LiPo has a cell with higher internal resistance, this will affect the performance of the complete battery pack. With " Swaytronic -Cell-Match" this problem is a thing of the past. Ultrasonic connection: The different cells (1S,2S,3S,4S,etc.) of a LiPo battery pack, are normally connected with a soldered tin joint. This, in addition to the small factor of additional weight, primarily increases the resistance and reduces the conductivity, which in turn negatively affects the performance of the LiPo. With Swaytronic's ultrasonic connection, this factor is minimized. The LiPo cells of the Best -Performance are connected with an ultrasonic welding. This has a positive effect on the weight and reduces the resistance of the connection, resulting in a higher current flow. Application RC - Jet, Airplane, Helicopter or Car. Swaytronic's Best -Performance, like ECO-Performance, covers a wide and deep segment of applications. Customer benefits More power with less weight. A power which is suitable for almost every application.
