12 FET IRFB3077 EM3ev Controller (Black Case) + Throttle. Purchased as part of a kit from EM3ev. I ended up using a Phaserunner instead of the Em3EV controller. $120. Free Priority Mail shipping from California. Will not ship international.

12 FET IRFB3077 EM3ev Controller (Black Case) is our Infineon Sensored Controller for 36V-50V battery packs and for motors with hall sensors. This is the same controller as our regular Infineon controller, but with a Black case and Water-Proof connectors.
Includes following functions as standard (uses the same Higo plugs on the throttle and ebrakes, as are used on the Bafang BBS Kits):
Water-Proof E-Bus cables for all accessories (similar type to Bafang BBS Kits) included with every controller.
Throttle and Ebrake uses the same Higo Connector as is used on the Bafang BBS Kits (optional extras).
3 speed switch (included as standard).
Cruise Function(included as standard).
Cycle Analyst plug, with Shunt Value Marked on case for CA Shunt calibration.
Programming header (inside case to keep things tidy) for simple programming flash via USB program cable (program cable is an optional extra).
Power switch on the case. Zero current drain when low power switch is powered off, so not necessary to disconnect when not in use, avoiding the sparks and damage that the uncontrolled current surge can cause damage to the connectors and battery.
