LiPo 7.4V 550mAh 20C Battery with MOSFET for Airsoft Electric Pistols is a new product of top-tier quality. Boasting quality rivaling that of the best players on the market and an affordable price, it features ultra-long battery life, even with limited space, and is comparable in size to a cigarette lighter! Optimal energy transfer is ensured with high-quality cables and plugs which minimize losses and heat, while the NanoSafe® system and Subzero Power® technology greatly improve low temperature performance and reduce self-discharge. 20% more charge cycles, and increased internal resistance and voltage under load make this an ideal choice for beginners and professionals alike. LiPo batteries are the successors of Li-Ion, offering a great capacity-to-size ratio in a very compact package. They don't have a memory effect and can be recharged infinitely without a prior discharge. Discharging below 3V/cell and overcharging over 4.2V/cell
