Accurate Mounting Solution for YZ-4S

The Yokomo S4-118BM Battery Mount Set is crafted to sit precisely on the YZ-4S chassis and clamp the battery solidly. Its fit prevents the pack from shifting during hard driving, helping the car stay true to set-up.

Consistent Handling With Less Pack Movement

Fitting the S4-118BM reduces the energy lost to pack movement, resulting in steadier steering and more repeatable cornering. That stability is useful when dialing in suspension or testing tyre choices.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will fitting this affect lap time consistency?

By keeping the battery fixed, the mount helps maintain setup consistency and can reduce lap time variance caused by pack movement.

How should I maintain the mount?

Inspect mounting screws regularly and check for play after heavy runs. Tighten to spec and replace any damaged fasteners to preserve fitment.

Can I add extra security like a strap?

Some drivers add a soft strap or non-slip pad under the pack for added peace of mind, but the S4-118BM is designed to hold standard YZ-4S batteries without extra hardware.
