Ultimate 75V Esk8 Build: Flipsky 7070 & UBOX Monster Setup

Описание: Getting Ready For Summer.

My Electric Mountain Board needed an upgrade as one of the motors was not working correctly.
One of the windings had broken so I decided to get two new powerful motors
18S 75 V .
And also build a 75 V battery to go with it .
Using my existing Ubox 75 V 200 amp controller.

Upgrading your electric mountain board with new motors and building a compatible battery sounds like an exciting project. Here are a few things to consider during your upgrade:

1. **Motor Choice**: ive chosen motors with an 18S 75V rating, which means they can handle higher voltages and should deliver more power. Ensure that the new motors physically fit your board and are compatible with your existing drive system.

2. **Battery Build**:
**Configuration**: An 18S configuration means a series of 18 cells. Lithium-ion cells typically have a nominal voltage of 3.7V, so an 18S battery would have a nominal voltage of approximately 66.6V and a fully charged voltage of about 75.6V.
**Cell Choice**: Use high-quality cells with an appropriate discharge rate to handle the demands of your motors and prevent overheating. Cells like the Samsung 30Q or Sony VTC6 are popular choices for high-drain applications.
**Battery Management System (BMS)**: Implement a BMS that can handle the voltage and current demands of your setup. The BMS will manage charging, balance cells, and protect against over-discharge and over-current scenarios.

3. **Compatibility and Calibration**:
Ensure your Ubox 75V 200A controller is programmed correctly for the new motors and battery configuration. Check the settings for current limits, voltage cutoffs, and motor parameters.
You might need to recalibrate your controller to suit the new specifications of your setup for optimal performance.

4. **Safety Considerations**:
Double-check all electrical connections and ensure they are secure to prevent short circuits.
Insulate all connections properly to avoid electrical hazards.
Consider adding additional safety features like voltage alarms or temperature monitors to keep tabs on your system's health.

5. **Testing**: After assembly, conduct thorough testing in a controlled environment. Start at lower speeds to ensure that everything functions correctly before pushing the system to its limits.

6. **Legal and Terrain Considerations**: Be mindful of the legal speed and power limits for personal electric vehicles in your area and choose terrain appropriate for your equipment's performance.

Make sure to consult user manuals and resources specific to the products you're using for detailed instructions and recommendations. Enjoy your upgraded ride!
