Kyosho LA408 - Battery Holder (ZX7.5)  [KY-LA408]

Battery Holder for LAZER ZX7.5

The Kyosho LA408 battery holder is a direct replacement component intended for the LAZER ZX7.5 chassis, serving as the mounting interface that secures the battery pack inside the racing-scale model. This article focuses on fitment, basic installation considerations, and the part's role in setup and tuning without assuming any unseen details.

Fitment and installation are straightforward: the holder aligns with the LAZER ZX7.5's existing battery bay mounting points, using the original screw locations and fasteners. When replacing the holder, verify orientation so connectors and wiring remain accessible for the ESC and motor plumbing, and check that the pack sits flush to avoid body interference.

As a tuning element, the battery holder defines the fixed position of the pack, which affects fore-aft balance and handling feel. Use the holder to repeatably return a chassis to a known setup during suspension or weight-distribution adjustments; small changes in battery position can alter traction and steering response on tight on-road tracks.

For maintenance, remove the body shell and loosen the existing fixings, swap the holder into the chassis, and recheck wiring routing before final tightening; consult your LAZER ZX7.5 setup notes to maintain consistent battery placement for testing and race preparation.
