Choosing the Right Fuse for Your Build
You can't just slap a standard automotive blade fuse onto a 15kW electric dirt bike; it will instantly pop the moment you crack the throttle. You need a fuse rated for both the voltage and the peak amperage of your specific setup.
1. Our Recommended Fuse for most Systems
120V, 250A Fuse Rating: (Up to 30Kw based off of Amp output)
| Continuous Amp Output | Rated Minutes | Rated Seconds |
| 337.5A | 30 Min | 1,800 Sec |
| 375A | 7.5 Min | 450 Sec |
| 500A | N/A | 15 Sec |
| 1500A (Peak) | N/A | 1 Sec |
It is very rare that you will pull above 500 Amps of power on most setups under 30Kw. If you do, you can maintain 500 Amps for 15 Seconds. Most Systems will draw a quick peak and then go down to a continuous output. If your Continuous output is around 300Amps then you will never have any issues using this fuse! If there is a random peak in the system this fuse will still be fine for one second up to a 1,500 Amp Peak. If there is a failure and the battery dumps a huge output this Fuse will break and save you from thermal runaway!
120V, 300A Fuse Rating: (Recommended on a 30kw - 40kw setup)
| Continuous Amp Output | Rated Minutes | Rated Seconds |
| 405A | 30 Min | 1,800 Sec |
| 600A | N/A Min | 15 Sec |
| 1050A | N/A | 5 Sec |
| 1800A (Peak) | N/A | 1 Sec |
120V 350A Fuse Rating: (Recommended on a 40kw - 50kw setup)
| Continuous Amp Output | Rated Minutes | Rated Seconds |
| 472.5A | 30 Min | 1,800 Sec |
| 700A | N/A Min | 15 Sec |
| 1225A | N/A | 5 Sec |
| 2100A (Peak) | N/A | 1 Sec |
120V 400A Fuse Rating: (Recommended on a 40kw - 50kw setup)
| Continuous Amp Output | Rated Minutes | Rated Seconds |
| 540A | 30 Min | 1,800 Sec |
| 800A | N/A Min | 15 Sec |
| 1400A | N/A | 5 Sec |
| 2400A (Peak) | N/A | 1 Sec |
Installation
Note: Always verify the correct fuse rating for your application before installation.
