Stop throwing away alkaline batteries and unlock the true speed of your 1/28 scale racer. The Kyosho Speed House 800HV is the gold standard for Mini-Z power.
While generic rechargeable AAA batteries are designed for low-drain devices like TV remotes, these "High Voltage" (HV) cells are engineered specifically for high-drain RC motors. They maintain a higher sustained voltage curve under load, giving your Mini-Z consistent "punch" (acceleration) from the start of the race right through to the finish line, rather than tapering off slowly like standard batteries.
Key Features
-
800mAh Capacity: Strikes the perfect balance between runtime and weight. Higher capacity cells (like 1000mAh) are often heavier and have higher internal resistance, which actually makes the car slower. 800mAh is the sweet spot for racing.
-
HV (High Voltage) Chemistry: Designed to peak slightly higher fresh off the charger and hold that voltage longer, giving you a noticeable top-speed advantage on the straights.
-
Matched Set of 4: Sold in a pack of four, exactly what you need to fill the chassis of a standard Mini-Z.
-
Reusable Power: Can be recharged hundreds of times if cared for properly, saving you a massive amount of money over store-bought alkaline batteries.
