Review: Very powerful and versatile but persistent and decent electrical skills/ knowledge is needed. - I have four of these in ex rental Ninebot max scooters. Ive used both the stock 10s battery pack as well as built my own battery packs of varying voltage. Even with the stock battery the performance is significantly better than the stock speed controller, much more torque and slightly better speed but where this controller really shines is when an option called field weakening is enabled. This will boost top speed on 10s to a little over an honest 30mph. There is a trade off with this and that is increased power consumption, the controller will also quick start getting hot and thermal throttling. I've tried unsuccessfully to resolve the heat problem by several methods. Even with the heatsink attached to a large fan cooled heatsink bonded with thermal epoxy I still run into thermal throttling after several minutes of full throttle. That said, Im pumping close to 3kw through this tiny controller at full throttle. This is a huge amount of energy and is very impressive. I've also been running this on 13s with no problem. Attached are logs of my scooter on 13s. I'm getting 37, 38mph, gobs of power. SI much motor is overheating to the point I drilled holes in the side covers to allow air circulation. It actually works. Lol.
Review: This version has 1 COMM port, but You need 2 COMMs to do both Bluetooth + IMU - I was hoping to build a OneWheel skateboard out of this hardware and discovered that the Flipsky Bluetooth module takes up the exact same COMM port that the footpad and IMU sensor are using. If you want to add Bluetooth connectivity to your DIY OneWheel board, make sure to buy a VESC that has two COMM ports, or 1 COMM (UART1) and a second comm port (UART2).

## Questions & Answers

**Q: Would a 32v 10s2p battery (a bunch of 18650) be good for this?**
A: Yeah you’ll definitely just need to run the VESC tool wizards and go through the configuration which will setup the motor parameters and you can customize the battery cut-off voltages to whatever you need them to be. Hard to say what kind of torque/drive power you’d get out of a nominal 32V vs nominal 40V without knowing your motor specs though

**Q: Is this the vesc4.20 plus version?**
A: Yes, I believe so.

**Q: will this control a 24v 3000w dc brushless motor?**
A: Only if it says for a BLDC MOTOR

**Q: About the power button? Would I need the anti spark system or will the button they sell that plugs into it work?**
A: you need the anitspark

### ⭐ Troubles
*by K***H on January 7, 2024*

The wire for the battery is made for a xt90 connector a xt60 connector is way too small. If you haven’t solder before do not buy trust me you will regret it. Plus programming it was another struggle on it’s own.
