Available at RC Model Shop, these genuine ARRMA jumpers are supplied in a convenient four-pack and feature durable composite construction that stands up to regular handling and adjustment.

Whether you own one MEGA brushed RC car or several, this pack provides peace of mind and the flexibility to switch settings whenever you need to.
Key Features
- Pack of Four Jumpers — This set contains four replacement composite jumpers, providing multiple spare parts so you can keep one set in your tool kit, one in your car bag, and extras at home or the workshop. Having multiple jumpers means you're never without a way to reprogram your MEGA ESC.
- Durable Composite Material — The jumpers are constructed from robust composite material that resists wear and damage from repeated use. The strong construction ensures these parts maintain their integrity through countless programming sessions and configuration changes without cracking or degrading.
- Custom-Shaped Easy-Grip Tabs — The distinctively shaped tabs make the jumpers comfortable and intuitive to grip, reducing frustration during ESC configuration and making it easier to position them accurately on the speed controller's pins. This thoughtful design minimises handling errors and speeds up the setup process.
- Program Battery Modes — Use these jumpers to switch your MEGA brushed ESC between NiMh battery mode and LiPo battery mode, allowing you to optimise performance for whichever battery chemistry you're using. This flexibility is crucial for RC enthusiasts who own multiple battery types.
- Enable Low Voltage Cutoff — These jumpers allow you to activate the low voltage cutoff protection when running LiPo batteries, a critical safety feature that prevents over-discharge and battery damage. This functionality protects your valuable LiPo cells and extends their lifespan significantly.

This is useful for customising your driving experience or limiting reverse function during specific activities.
- Standard Equipment on All MEGA Brushed Controllers — These jumpers are the original components supplied with every ARRMA MEGA brushed speed controller, ensuring perfect compatibility and authentic performance. If you already own a MEGA ESC, you know exactly what to expect from these replacement parts.
