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: During the assembly of the battery packs, it is ensured that only cells with identical internal resistances are combined. Your advantage: The performance of the LiPo battery is only as strong as its weakest link. If a LiPo has a cell with higher internal resistance, it affects the performance of the entire battery pack. With "Swaytronic Cell Match," this problem is a thing of the past. Ultrasonic Connection: The various cells (1S, 2S, 3S, 4S, etc.) of a LiPo battery pack are typically connected with a solder joint made of tin. This not only adds a small amount of extra weight but primarily increases resistance and reduces conductivity, which negatively impacts the performance of the LiPo. With Swaytronic's ultrasonic connection, this factor is minimized. The LiPo cells of the Best Performance are connected using ultrasonic welding. This positively affects the weight and reduces the resistance of the connection, leading to a higher current flow. Application: RC jet, airplane, helicopter, or car. Like the ECO Performance, Swaytronic's Best Performance covers a wide and deep range of applications. Customer Benefit: More power at a lower weight. A power that meets the needs of almost any application.
