This is a high-quality 1200mAh 7.4V 25C Li-Po battery Tamiya Stick, manufactured by the reputable American company Titan Power. Known as Liti-LiPolimer packs (LiPo), they are the successors to lithium-ion (LiIon) packs and are highly favored for their exceptional capacity-to-size ratio. With a high current capacity, these packs are compact, making them suitable for almost any AEG replica. Moreover, they do not experience any memory effect and can be charged frequently without discharge. It's important to remember to charge them correctly, avoiding overcharging above 4.2V per cell or discharging below 3V per cell. Additionally, their low percentage self-discharge makes them ideal for long-term storage, though it's essential to monitor the pack's energy level to prevent irreversible chemical reactions that may cause damage. For optimal performance, they should be charged at room temperature and balanced during charging using a service plug, which is
