The Nucular X6F, winner of Best New E-Mobility Technology at the 2026 E-Mobility Awards, packs up to 15 kW of peak output into a 227 g controller with roughly the footprint of a credit card. Against the published specifications of its 12 kW 12F and 27 kW P24F units, that is more than three times the peak power per gram, and the company says getting there meant rethinking heat, current and signal integrity.
Holding peak power for longer in the Nucular X6F
Peak ratings describe short-duration limits, and heat decides how long a small controller can hold them. The X6F produces that output with field-oriented control, and its top-side cooled TOLT MOSFETs pass heat from the top of each transistor straight into the aluminium enclosure, so less of it builds up in the board under heavy load. Nucular says that lets the controller sustain peak power nearly twice as long, because a top-side cooled package routes heat to a heatsink or enclosure without first sending it through the circuit board.
Clean signals and open tuning on the Nucular X6F
Switching that much power generates electrical noise, so the X6F keeps its microcontroller on a physically separate logic board to limit how much of it gets through. On the power side, an 8-layer heavy-copper board with ultra-low-ESR polymer capacitors handles current spikes. The Nucular X6F also runs bare-metal firmware with more than 200 tuning parameters. It connects over LEVCAN, the open Light Electric Vehicle CAN protocol that Nucular maintains for a wider platform whose components work separately with devices from other manufacturers.
Designed for off-road bikes and fleet duty
Nucular targets the X6F at high-performance electric dirt bikes and commercial fleets, and backs it with recessed IP67 waterproof connectors, a three-year warranty and a field failure rate it reports at below 1%. Developers who would otherwise design these components in house can also go to Nucular as an OEM partner, an arrangement it pitches as cutting research, development and testing costs, with ongoing technical support and software updates behind it.
The X6F comes after a decade of ground-up circuit design and testing. Nucular’s range is still growing, with a battery management system listed as in development and open for preorder, and the company is already focused on its next wave of power electronics innovations.
