Everything you need to know about: The Thor400
The Thor400 is a 32s (134v) VESC that is a a pioneer in the High Voltage Vesc based, Onewheel market. This controller is a flagship controller in Fungineer related products such as our Complete Controller Box modules and preassembled boards. This controller was built by and for the Vesc based, Onewheel community. Thank you to all the individuals who have greatly contributed to this controllers formation, some important names like Surfdado, Mario Contino, Nico Aleman, and many countless others. Your dedication to the longevity of this community does not go unnoticed.
VERY IMPORTANT NOTES FOR INSTALLATION OF THOR400'S
- Please be mindful of the exposed mosfets, improper mounting of the controller may lead to the shorting of critical components
- You MUST use a discharge fuses rated for your battery. You risk controller failures that will lead to thermal runaways if not using a fuse.
- You MUST have an ERPM limit on this controller. A freespin on a HIGH VOLTAGE controller can damage critical components
