Build with confidence
We’re launching four key components—engineered to redefine EV conversions. Each embodies our promise of quality, reliability, and builder‑first design.
The System Behind Every Solid Build
Every component is crafted with purpose — combining premium engineering, modern technology, and real-world builder insight.
Built for Builders
Formosa kits are designed with you in mind: they install effortlessly, minimize troubleshooting, and just feel right the moment you start bolting them in.
Open & Compatible
Our systems integrate seamlessly with your existing setup, supporting open protocols and plug‑and‑play parts that professionals and DIYers alike can trust.
Powered by Modern Tech
We rely exclusively on new, OEM‑grade components to deliver top‑tier performance and unwavering reliability—no guesswork, no do‑overs.
Modular by Design
Customize your build at your own pace: begin with what you need today and expand tomorrow with scalable kits and future‑ready hardware.
Driven by vision. Built by hands.
Formosa EV was founded by two innovators — Zack Hwang & Azizi Tucker From NASA deep-tech startups to Tesla's global supply chain, they bring decades of engineering expertise, hands-on grit, and a deep respect for car culture.

Frequently asked questions
What is Formosa EV?
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.
Who is it for?
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.
Why choose Formosa EV?
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.
No Salvaged Parts: All components are brand new with modern EV technology.
What is the Formosa Standard?
Our Promise:
OEM Quality: Products that exude precision craftsmanship and engineering.
Human-Centered Design: Intuitive systems that just work, are “nice” to use, and beautiful to showcase.
Built for the long haul: Future-proof builds that work for decades and upgradable if desired.
Which products can I preorder?
We're launching four foundational products to kickstart your build:
Liga VCU: The “brain” of your EV: App-controlled, CAN-free vehicle control unit.
Liga Harness: Custom-fit wiring: Machine-crimped, 100% OEM-compatible harnesses.
Forte Motor: 130kW powerhouse: Integrated inverter, pre-wired HV cables (TECO TP130).
SOL HV Battery: Modular power: Enclosed, BMS-equipped packs (8–16 modules).
What’s coming next?
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).
How does the MasterStack work?
The Formosa MasterStack is divided into 5 layers:Liga (controls), Sol (battery), Ria (Power Flow), Forte (motor), Brisa (Thermal). Mix and match components or start with a core kit. Scale as you grow.
Are these components compatible?
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.
What builder resources are available?
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.
How do I stay updated?
Subscribe to our Builder’s Newsletter for:
- Early access to new products.
- Exclusive discounts.
- Updates on builds using the Formosa MasterStack
How do I begin my build?
Order a starter kit (FVCU + Harness + Motor + Battery).
Join our community for pro tips and troubleshooting.
Scale Up with future MasterStack layers.
