The Redox company's Redox LiPo 850 mAh 7,4V 20C battery offers a new standard in quality for airsoft replica batteries. Each cell is carefully inspected and paired by hand, ensuring unparalleled precision and excellence. With individual ID numbers, the battery's full history can be tracked and all products are backed by a 100% guarantee of replacement in case of any manufacturing defects. Thanks to their excellent weight to dimension ratio and long lifespan without energy loss, these lithium-ion-polymer (LiPo) battery packs are highly sought after successors to lithium-ion (LiIon) battery packs. One of the main advantages of LiPo batteries is their exceptional capacity to size ratio, making them suitable for nearly all AEG replicas. These batteries do not experience the memory effect and can be frequently charged without being fully discharged first, making them very convenient and beneficial. However, it's important to keep in mind not to let the battery deplete beyond 3V per cell
