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.

What products are available now for preorder?

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).‍

What future products are planned?

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).

Why choose Formosa over competitors?

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.
