Stormcore™ 2.0 (Electronic Speed Controller)
Couldn't load pickup availability
Introducing the all new Stormcore 2.0, inspired by the legendary Stormcore 100Dx. Stormcore 2.0 sets a new standard for unmatched power and reliability. With nearly double the power output capability of any previous generation, Stormcore 2.0 will get you where you need to go - and fast.
The onboard microcontrollers enable precise, real-time, and fully independent control of two motors, delivering power as needed to fuel your next adventure. Featuring an anodized CNC aluminum case, it is built to offer maximum durability and thermal performance. The rear portion of the case is a plastic composite, allowing clean RF reception for the internal bluetooth module so you can connect to your board remotely for logging stats and tuning performance (for advanced users only, changing settings voids the warranty on your board). An integrated 4 GB memory chip allows logging data directly to the device.
Last but not least, Stormcore 2.0 was developed in collaboration with the VESC Labs team, the best group of engineers in the game.
OPERATING CONDITIONS
The recommended maximum operating voltage is 100V (22S). Sustained motor current will vary by application and environment but our extensive testing has shown excellent thermal performance at settings up to 200 max motor amps per motor (pulsed) and the controller is capable of sustaining 140 motor amps.
INTERNAL POWER SWITCH
An included switch with RGB LED controls an internal anti-spark switch to safely toggle power of your system. The internal anti-spark was designed for maximum reliability and longevity and testing has shown it to be extremely robust. When configured the switch also displays the current battery level of the board as a color output on a continuous gradient from red-blue-green for 0-50-100% battery remaining.
INTERFACE PORTS
An XT90 port is cleverly nestled within the assembly to save precious space in the enclosure that would otherwise be needed for this high-power connector. The motor leads are 4mm Female Bullet Connectors. Mating bullets can be ordered from many online vendors (the part number you will need is GC4011-M). There are ports for hall sensors, motor temperature sensors, and communication busses for external devices. The JST PH 2mm connectors adhere to the standard outputs featured in most VESC based ESCs making it compatible with many external devices. It also features a USB C port for connecting and configuring via computer.
SOFTWARE AND FIRMWARE
Stormcore 2.0 will be fully supported by our Lacroix app coming soon, where you will be able to see your stats, track rides, and more. Stay tuned!
The firmware of the Stormcore is VESC™ based and is compatible with all third-party apps supporting the latest firmware, but we recommend using only the official VESC™ software hosted at https://www.vesc-project.com/
PLEASE READ CAREFULLY BEFORE PLACING AN ORDER;
Stormcore 2.0 is VESC based. It's advisable to read and understand the safety information, limited warranty statement, licensing, terms and conditions of VESC Tool which you must accept before using the tool to program any VESC based ESC. Learn more here: https://vesc-project.com/

We recommend you use the settings above as limits. Not all Projects can handle this much power. The e-tray needs to be very well heatsunk and we recommend you adjust your values according to your set up with these numbers as the upper limits.
As we use the Stormcore in our own boards, they have been stress tested over thousands of units. However, just because they work for us does not mean it will be perfect for your setup; it's your responsibility to build a battery and hook it up to a sentinel and BMS according to the rules of the art, use proper heat sinks and cable management, understand the conditions of use and do the research on how to operate VESC based on our Stormcore™ limits.
