Lock Your Battery Pack in Place

The Kyosho UM581 battery holder was developed for the Ultima SB chassis to hold battery packs securely through jumps and bumps. It is a practical spare for drivers who want consistent power delivery under demanding conditions.

Built to Take Impacts

Using sturdy components, the Kyosho UM581 resists flex and vibration to keep your battery fixed in position. That stability helps protect wiring and connectors from repeated shock loads during off-road runs.

Seamless Chassis Integration

This holder fits the Ultima SB Dirt Master setup and installs with minimal effort, allowing quick swaps between practice sessions or races without altering other parts of the car.
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.

Will the Kyosho UM581 accept different battery sizes?

The holder is sized for standard packs used in the Ultima SB layout. Slimmer packs may need padding while larger packs may not fit without modification. Check pack dimensions before buying.

Are there recommended batteries to use with this holder?

Most commonly used LiPo packs that match the Ultima SB battery bay will work fine. Make sure balance leads and connectors have clearance when the holder is fitted.

How long does installation take for an experienced hobbyist?

For someone familiar with the chassis, swapping to the UM581 typically takes only a few minutes using standard hand tools.

Any tips for keeping the battery secure during long runs?

Double-check that mounting screws are tight and that the pack sits flat in the holder. Use light foam packing if there is slight play to prevent movement.
