Those High-NRG Cells have a permanent Discharge capability of current 10-12C (= 13,2A) and Max Dis-Charge current of 20C (27A) for up to 5sec. Charge current is up to 1c. A cell weight is 41gr, a bit . more than foil-packed Li-Po cells of same capacity, but the excessed weight is well explained - the robustness of the cell is based on it. Many  special protective functions .  High-NRG Cells have a cylindrical metal housing that protect them against mechanical damage . Therefore they are much better protected, as well the model, and your investment into those cells. High-NRG Cells have a temperature safety device, which cut off the current flow during faulty operation or short cut but the cell will not explode, as can happen with other brands. The High-NRG Cells offers new possibilities for RC pilots: Achievement for longer running times with fewer weights! This leads unbelievable 3D aerobatics in Helis to 20min long flights or. Aerobatics machines fly better by the program, because they are more easily and also RC Cars drive much longer

Each cell is Equipped with Soldering tags for easy packs preparation

Please note those are High Discharge cells. Using Digital Servos must be used with those cells. Other competitors packs will not hold high Discharge and will put your model in Crash danger
