The BKB Xenith ESC is a fork from the very popular Focbox Unity ESC hardware branch. It has taken the Unity and improved it in the areas that needed work and created an awesome value ESC that is fully compatible with the current and future VESC Project firmware and VESC tool software admin (note warranty voided by changing firmware). It also has it's own Xenith Easy UI if you don't want the depth of info the VESC tool can offer. The Xenith comes with Bluetooth connection built in as standard and MR60 Motor connectors and a new updated switch in the V2 version and silicone protective cover. If you are powering an electric skateboard or mountainboard then the Xenith is a great option for high power hungry riders. But if you are running large motors and wheels at high motor amps then the Xenith speed controller does need an extra heatsink with air cooling to keep it all cool in use.
Please Note: BKB Xenith V2.1 comes without IMU or CAN chips due to global shortages. This is still fine for most esk8 applications apart from 4wd which would need to be done with PPM Split instead of CAN. The new V2.1 comes with Black silicone case with Red Heatsink which looks super cool!
This is a speed controller designed for DIY builders with some experience of setting up and configuring controllers and may involve soldering and changing connectors on motors or ESC. If you are using this we strongly recommend using a external heatsink to disperse heat otherwise you can damage the unit in use. We do sell a simple extra heatsink for these controllers. All Xeniths are checked before shipping on known hardware and there is a warranty that you need to register your controller if you need to claim. See info below about BKB warranty.
