Cold pit tables do odd things to batteries. When the pack is chilly, the car can feel like it read the rules and chose quiet quitting. The SKYRC TWneo Battery Warmer Sleeve is made for racers who already like the TWneo idea and want the same controlled heating approach for a compatible RC battery pack.

This is an add-on sleeve only. The SKYRC TWneo controller is required and is not included. It is intended as an extension for an existing TWneo setup, whether you have the tire warming cups or the warming belts. Plug the battery warmer sleeve into your TWneo controller and use the system you already have instead of buying another dedicated battery warmer box.

The sleeve has a battery-specific temperature guide conveniently printed right on it: 20-35C is the Safe Zone, 36-45C is the recommended Optimal Zone, and 46-55C is Race Mode for short-time use only. That matters, because battery warming and tire warming are not the same job, even if they are both trying to make race day slightly less chaotic.

Always follow your battery manufacturer's temperature limits and your class or track rules. Never leave a battery unattended while charging or warming, and keep the flap sealed during charging or warming as marked on the sleeve.
