Secure Mounting for the Ultima SB

The Kyosho UM581 battery holder is made for the Ultima SB lineup and keeps your battery firmly seated during high-speed runs and rough track sections. This spare part focuses on reliable retention so racers spend less time fixing packs and more time on the track.

Track-Proven Construction

Made from durable materials, the Kyosho UM581 battery holder gives a snug, vibration-resistant fit within the Ultima SB chassis. Its robust build helps prevent disconnection or movement caused by hard landings and impacts.

Tailored Fit for Dirt Master Layouts

This holder is engineered to match the Ultima SB Dirt Master configuration, offering straightforward installation that swaps in without chassis modification. The result is minimal downtime and consistent power delivery during events.
Remark :
Due to limited stock availability, please notice that some Kyosho 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.

Is the Kyosho UM581 only for Ultima SB models?

The UM581 is designed specifically for the Ultima SB family. Fitment on other Kyosho models is not guaranteed without checking chassis dimensions first.

What tools do I need to install this holder?

Basic hobby tools such as a small Phillips screwdriver and a hex driver are usually enough to remove the old holder and fit the UM581.

How does this part help prevent power loss on track?

By holding the battery securely, the UM581 reduces movement and stress on connectors, lowering the chance of mid-run disconnection and ensuring steady voltage to your electronics.
