Preparing a Nami Burn-E: Battery, Motors, Steering, and Wiring
The Nami Burn-E is a highly regarded platform for modifications, thanks to its adjustable suspension and natural riding position. To achieve even greater performance, three common limitations are addressed: a battery with limited discharge capacity, motors that quickly reach their maximum output, and steering that exhibits excessive play. Here's how the workshop approaches modifying a Burn-E, in order.
The essentials
- The original battery is the main limiting factor: it's the first thing you should replace to gain more power.
- Larger motors can be installed on Nami models using dedicated axles and spacers.
- A titanium steering column eliminates play in the steering system, and is available in various lengths to suit different applications.
- The brakes must be functioning correctly before increasing the power output.
1. Brakes and steering first
Before adding power, the machine must brake and steer reliably. For braking, please refer to our guide on braking for a powerful electric scooter.
For steering, our grade 9 titanium stems for the Nami Burn-E, with an aluminum 7075 headset and handlebar adapter, eliminate play and loosening of the original stem. They are available in several lengths: 38 cm for a lower riding position on the track or for smaller riders, 50 cm, and custom lengths. They require a mountain bike-style handlebar. See our mechanical parts.
2. The battery: the key factor
According to our data, the original Burn-E battery is limited to a peak of 98A. This limitation is what causes the cut-offs and power drops during acceleration or when going uphill (see our guide on batteries and BMS systems that cause cut-offs).
Our Performance 80V 40.5Ah battery for Burn-E, E2, and E3 models, assembled with Molicel P45B cells in an aluminum casing, boasts a peak current of up to 450A, and features a connected BMS that allows you to monitor cell consumption and status from your phone. We also offer 72V replacement batteries and custom versions. See our batteries for Nami.
Switching to a higher voltage than the original requires checking the controllers, the charger, and the accessories: see our guide on upgrading to a higher voltage.
3. The Motors
Two options are available:
- motors of the same size, such as our SHS60 and SHT60, which can be installed on the Nami Burn-E;
- Larger motors: Our XHS and XHT models, with diameters of 75 and 80 mm. These require widening the arms of the Nami: our stainless steel axle and spacer kit, manufactured in France, was designed specifically for these motors mounted on our CNC aluminum rims, and only for them, to ensure proper spacing and alignment.
The choice between High Speed and High Torque is explained in our guide High Speed or High Torque.
4. Wiring and Controllers
Changing motors or controllers on a Nami requires redoing the wiring: phase and sensor connectors, power supply, controls. We offer a plug-and-play wiring harness for Nami, so you don't have to rewire everything yourself. The power cables must be sized appropriately for the new currents: see our guide on power cables and connectors.
For the controllers themselves, please refer to our controller guide and our comparison.
Workshop tip
On a Nami, be sure to allocate time for suspension adjustments after any modifications: a heavier battery and larger motors will alter the machine's balance.
And what about the law?
A modified Burn-E is a machine for private tracks or off-road use: on public roads, an electric scooter must be limited to 25 km/h. See our guide on laws and unlocking.
Frequently Asked Questions
Is this spacer kit compatible with other motors?
No. It was calculated for our XHS and XHT motors, both 75mm and 80mm in diameter, and designed for use with CNC aluminum rims. With a different motor, the spacing and alignment cannot be guaranteed.
Is the Performance battery compatible with all Burn-E models?
Our Performance 80V 40.5Ah battery is designed for the Burn-E, Burn-E 2, and Burn-E 3 models. Please check the product specifications to ensure compatibility with your specific model version, and to determine the appropriate controllers for use with its voltage.
Should everything be changed all at once?
No, and it's even discouraged. Make changes incrementally, testing after each one: this way you'll understand what each modification does, and you'll be able to identify the source of any potential problems.
