X4 Cage Autostart battery, 3.7V LiPo pack

The X4 Cage Autostart battery brings the specified 3.7 V LiPo power pack and 220 mAh capacity needed for compact RC use into one small-format unit. Its silver pouch-cell format, red and black connection leads, and white 2-pin plug create a layout that fits neatly into model setups where every millimetre of space counts. With an energy rating of 0.81 Wh, this rechargeable battery is defined by clear electrical data rather than vague compatibility claims. The cable-mounted connector supports straightforward installation in matching systems, and the lightweight pack format suits small vehicle platforms and model electronics that rely on a compact power source. The visible warning tag attached to the lead marks a handling instruction directly on the battery assembly, keeping the operating note close to the connector itself. Batteries are not included beyond this listed battery pack. In use, the pack suits replacement duty for the X4 Cage Autostart and similar compact applications where the required voltage and connector format need to match exactly. For hobby benches, pit boxes, or regular running preparation, it adds a clearly specified LiPo option that keeps compatible RC equipment ready for the next session.
