We’re kicking things off with four cornerstone components — thoughtfully engineered, currently in development, and built to set a new standard in EV conversion.
Each product reflects our long-term commitment to quality, reliability and the builder experience.
Every component is crafted with purpose — combining premium engineering, modern technology, and real-world builder insight.
Formosa kits are intuitive, frustration-free, and ready to go.
Only 100% new, 2025-grade components- no salve.
Engineered to work with your setup, not against it
Buy what you need, upgrade as you grow
Your roadmap to understanding Formosa EV's ecosystem, products, and vision.
Formosa EV is a modular electric vehicle (EV) conversion ecosystem designed for builders, restorers, and shops. We combine OWEM-grade engineering with open-source flexibility, offering components which are modern, reliable, and scalable. Whether you're a DIYer or a professional shop, our systems are built to simplify your build and grow with your needs.
DIY Enthusiasts: First timers or hobbyists who want clear guides, gplug-and-play parts, and affordable modularity.
Restoration Shops: Professionals preserving classic cars but needing modern, heritage-compatible EV compnents.
EV Conversion Shops: Business requiring scalable, compliant systems to reduce build time and costs.
We’re launching four foundational products to kickstart your build: Liga VCUThe “brain” of your EV: App-controlled, CAN-free vehicle control unit.
Liga HarnessCustom-fit wiring: Machine-crimped, 100% OEM-compatible harnesses.
Forte Motor130kW powerhouse: Integrated inverter, pre-wired HV cables (TECO TP130).
Sol HV Battery:Modular power: Enclosed, BMS-equipped packs (8–16 modules).
The Formosa MasterStack will expand to include:
- Brisa HVAC Kits (cabin heating/cooling, battery thermal management).
- Ria Power Flow upgrades (ultra-fast chargers, smart power distribution modules).
- High-power Sol Battery Packs (824V configurations).
- Advanced Liga Displays (driver dashboards, customizable interfaces).
No Salvaged Parts: All components are brand new with modern EV technology.
Builder-Centric Design: Wide component support, plug-and-play integration, and modular upgrades.
Tested by Pros: Systems are road-proven and shop-validated.
Taiwan-California Fusion: Precision engineering meets hands-on car culture.
Yes! Our systems are model-agnostic and designed for:
- classic cars and trucks.
- Manual or automatic transmissions.
- 12V/ 24V systems.
Provided custom wire harnesses, and CAD files ensure seamless integration.
Compatability guides (to be done)[ notes ] -- why pre 90's cars are better candidates
Detailed Installation Guides: Step-by-step instructions and videos, wiring diagrams, spec sheets.
CAD/DBC Files: For custom brackets or integrations (request via email).
Community Forum: Collaborate with other builders and Formosa engineers.
