This product is a 1S LiPo battery designed for ultra-micro RC aircraft and lightweight hobby applications that require compact size and low weight. It delivers a 3.7V nominal output with a 150mAh capacity and a 45C discharge rate, providing short bursts of power for small-scale flight performance. The PH 1.25 connector is commonly used in ultra-micro RC systems for plug-and-play compatibility. Its small form factor makes it suitable for indoor planes, micro drones, and other lightweight builds where space and weight are critical. The high discharge capability helps maintain responsive throttle control during flight despite its small capacity.
