Kyosho IF507 5mm Battery Cushion Inferno VE

This is the 5mm battery cushion used in Kyosho's electric Inferno chassis.

A LiPo pack sitting directly against a hard plastic tray is a problem waiting to happen. Every landing and every hard impact drives the pack into the tray floor, and repeated compression damages cells on a soft-case pack, while constant vibration works the pack loose in its cradle. A loose battery is worse still, because a pack shifting under braking and cornering moves a significant share of the car's mass around and makes handling inconsistent from lap to lap.

The cushion addresses both. It absorbs impact loading before it reaches the cells, and it takes up the dimensional differences between battery brands so a pack sits tight in the tray without needing to be over-clamped by the straps.

At 5mm this is the thicker of Kyosho's two cushions, and it is the one to use when a pack sits loose in the tray with noticeable space around it. A 2mm version covers packs that already fit closely. Kyosho lists this in the same battery tray assembly as the IF503 tray and IF506 strap set for the Inferno VE and MP9e platforms.
