This 1000mAh 7.4V 25C Li-Po battery from Deans Stick is a top-quality LiPo pack produced by Titan Power, an American company with expertise in the industry. LiPo batteries, the next generation of lithium-ion packs, have a high capacity-to-size ratio, making them a great choice for any AEG replica. Unlike other batteries, they have no memory effect and can be charged frequently without needing to be discharged first. It is important to remember not to discharge below 3V per cell or overcharge above 4.2V per cell. With low self-discharge rates and a lifespan of 500-700 cycles, LiPo batteries are a reliable choice. They can operate well in low temperatures but should be charged at room temperature. To maintain their condition, it is recommended to balance the pack during charging using the included service plug.
