Speed King Tour expands its competition battery lineup with the SKT6400, a LiPo pack announced at 6400 mAh with a 160C discharge rate, designed specifically for 1/10 electric touring cars. This new reference combines features already proven on the SKT6600 and SKT6000, with the stated goal of low internal resistance to preserve throttle response and consistent performance throughout a full 5-minute race.

SKT6400 specifications

The Speed King Tour SKT6400 battery comes in ULCG (Ultra Low Center of Gravity) Stick Pack format, to make weight distribution tuning easier on a touring car chassis. Its stated specs: 6400 mAh, 7.4V, 160C discharge rate, dimensions of 139 x 47 x 19.5 mm for a weight of 243 g.

Speed King Tour states that this battery is approved for its own TC0 and TC1 racing classes, and that it was designed to suit both short technical tracks and faster, more open layouts.

Price and availability

The SKT6400 is announced at 12,800 yen before tax in Japan, with release planned for late September 2026.
