Over 100 sets sold! ✨️✨️ Thank you for viewing! These are Neo Champ batteries that I've created for many racers, and they've been very well-received! In Mini 4WD, batteries are directly linked to speed, second only to the motor! I have experience winning high-speed races using my creation method, and I've also received reports of other racers placing well and updating their time attack records! ✨️ I hope you'll enjoy the current Mini 4WD scene, which features many high-speed races! ✨️✨️ Each set takes time to make, so it's first-come, first-served. Thank you for your understanding. I also recommend purchasing these in combination with motors! ✨️ 【Recommended Purchase Set】 Motor & Counter Shaft & Batteries ✨️↑↑↑ Set for advanced speed all at once ✨️ This product does not guarantee certain victory or speed increases.
