Precision Fit for the YZ-4S Chassis

The Yokomo S4-118BM Battery Mount Set is tailored for the YZ-4S and holds the battery securely to reduce slop. The mounting solution helps keep the pack stable when driving over rough sections or kerb strikes.

Better Control Through Reduced Movement

Once installed, the Yokomo S4-118BM cuts down on pack motion that can upset suspension tuning. That steadier battery position makes throttle and steering inputs feel more consistent lap after lap.
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.

Can I use this with a different battery style?

It is built around the pack layouts common to the YZ-4S. Some alternate battery types may fit, but confirm dimensions and connector placement first.

Will this change my car balance?

The mount itself keeps the battery in the intended position, so any balance change is minimal. Most users find handling becomes more predictable rather than shifting mass noticeably.

Does it work with standard YZ-4S electronics?

Yes, the S4-118BM is compatible with the standard YZ-4S electronics layout. Ensure cables are routed safely to avoid pinching when the battery is tightened down.

Any tips for a tidy install?

Pre-fit the battery and run wires before final tightening. Use light threadlocker on metal screws if you race hard to keep fasteners secure.
