Clean, Quiet Power

Electric Motorsport, Inc.

Based in San Leandro, California, Electric Motorsport has pioneered electric propulsion systems and EV conversion kits since 2001.

From early EV conversions and award-winning electric motorcycles to today’s quiet, efficient marine electric drive systems, our engineers keep raising the bar with cutting-edge powertrains, programmable motor controllers, and reliable LiFePO₄ battery systems integrated with EMUS BMS.
We help OEMs, custom builders, conversion shops, and R&D teams deliver clean, low-maintenance, high-efficiency solutions that reduce noise, emissions, and operating cost.

Whether you’re powering a sailboat or tender, building a go-kart or motorsport EV, or converting lawn & garden/utility equipment, we design and supply the matched components: traction motors, inverters/controllers, chargers, BMS, wiring harnesses, throttles, contactors, gearing, and instrumentation—right-sized for your voltage, torque, and duty cycle with support for regenerative braking and precise throttle mapping. Our Native® modular platforms scale from prototype to production, giving you predictable performance, serviceability, and parts availability.

About Our Products

Electric Drive Systems

Electric Motorsport designs and builds high-performance EV drive systems for electric vehicle conversions, marine propulsion, and industrial electrification. From DIY electric conversion kits with matched motor, controller, and wiring harnesses to custom turn-key electric drive systems, every package is engineered for efficiency, power, and reliability.

Our DIY EV Kits simplify your project with proven components and expert support for cars, boats, bikes, and prototypes.

Our Turn-Key Systems arrive fully assembled, programmed, and tested—ideal for marine craft, utility vehicles, robotics, agriculture, and EV racing applications.

Lithium Iron Phosphate (LiFePO₄) Battery Systems

Electric Motorsport carries premium Lithium Iron Phosphate (LiFePO₄) batteries—the safest and most stable of all lithium chemistries. These advanced batteries deliver exceptional energy density, long cycle life, and thermal stability, making them ideal for electric vehicle and marine applications.

All LiFePO₄ battery packs require a quality Battery Management System (BMS) to balance and protect individual cells for maximum efficiency and extended lifespan. Our EMUS BMS offers compact, flexible, and intelligent control for precise cell monitoring and charging management.

For complete plug-and-play integration, Electric Motorsport also supplies Complete Battery Systems with matched chargers and wiring—pre-assembled for simple installation and optimal performance.
