High Voltage Fuse Kit & Replacement Fuses

High Voltage E-Moto Fuse Kit & Replacement Fuses

Protect your battery, controller and high-current electrical system with a proper 120VDC-rated fuse setup built for high-power E-Moto builds. Choose the 250A full kit for a new install, or grab a 250A or 300A spare fuse for an existing fuse holder.

✅ FITMENT

• E-Moto battery systems up to 120VDC, including 60V, 72V, 81V and 96V nominal packs
• Upgraded controllers, including EBMX
• Installs between the battery positive lead and the controller positive input

Does not replace basic 32V automotive fuses. Never use 32V fuses on a high-voltage E-Moto battery system.

Why 120VDC?

These are 120VDC-rated fuses. That doesn't mean they're only for 120V batteries. It means the fuse is rated for DC battery systems up to 120V.

Most E-Moto batteries are listed by nominal voltage, like 60V, 72V, 81V or 96V. A battery's voltage is higher when the pack is fully charged, so the fuse voltage rating needs to be higher than the battery's highest charged voltage. For most E-Moto builds, a 120VDC fuse covers the correct voltage range, including 96V nominal systems.

Which Fuse Should I Choose?

Use your controller peak-output setting as the starting point:

250A Full Kit

Best for: New installs on most common E-Moto builds up to 30kW peak output.

What's Included:

• 1x 250A 120VDC fuse
• 1x plastic fuse case
• 1x M6 serrated flange nut
• 1x M6 x 10mm ultra-low-profile socket head screw
• 1x M6 x 1.5mm thick washer
• 2x M6 x 1mm thick washers

Not included: Battery or controller wiring.

250A Spare Fuse

Best for: Riders who already have the fuse holder installed and need a replacement 250A fuse.

What's Included: 1x 250A 120VDC fuse.

Not included: Fuse case or mounting hardware.

300A Spare Fuse

Best for: Higher-output builds in the 30-40kW peak range using an existing fuse holder.

What's Included: 1x 300A 120VDC fuse.

Not included: Fuse case or mounting hardware.

Controller Warranty Note

Some controller manufacturers, including EBMX, require a fuse to be installed for warranty coverage. If your controller manufacturer requires a fuse, don't skip it.

How to Install

• Install the fuse between the battery positive lead and the controller positive input.
• Always disconnect the battery before working on the electrical system.
• If you're not comfortable working around high-voltage battery wiring, have the fuse installed by a qualified shop.
• Detailed installation instructions are included with the fuse kit.

Important: A fuse helps protect the bike's high-current electrical system during overcurrent events, but the correct fuse size still depends on your controller setup, battery and power level.

FAQ

Q: Which fuse should I choose?
A: Use 250A for controllers up to 30kW peak output, and 300A for 30-40kW peak builds.

Q: Will a 120VDC fuse work on my 72V or 96V bike?
A: Yes. 120VDC is the maximum rating, so it covers 60V, 72V, 81V and 96V nominal battery systems.

Q: Can I use a regular automotive fuse?
A: No. Basic 32V automotive fuses are not safe on high-voltage E-Moto battery systems.

Q: Where does the fuse go?
A: Between the battery positive lead and the controller positive input.

Q: Do I need a fuse for my controller warranty?
A: Some manufacturers, including EBMX, require a fuse for warranty coverage. Check your controller manufacturer's requirements.

Q: What's the difference between the full kit and a spare fuse?
A: The 250A Full Kit includes the fuse, fuse case and mounting hardware for a new install. Spare fuses are the fuse only, for an existing fuse holder.
