HCE Performance Launches Integrated Battery Hold Down + Disconnect Switch for 51/51R Applications

Race-engineered solution eliminates parasitic draw while elevating engine-bay integration

[San Francisco, CA] — [February 2, 2026] — HCE Performance today announced the release of its Battery Hold Down + Disconnect Switch for 51/51R, a premium, motorsport-grade solution designed to eliminate parasitic battery drain while delivering a compact, factory-level installation.

Evolving from HCE’s proven firewall-mounted battery disconnect, this new system integrates a custom battery hold-down, protective shield, and high-current disconnect switch into a single, cohesive assembly. Designed specifically for 51/51R battery sizes commonly found in Honda S2000 and Honda Civic platforms, the kit brings race-winning engineering and industrial design directly to the engine bay.

Solving a Common, Costly Problem

When vehicles sit unused for weeks or months, modern electronics—alarm systems, clocks, ECUs, and other modules—continue to draw power, often leaving owners with a dead battery when they’re ready to drive. Trickle chargers offer a workaround, but introduce clutter, inconvenience, and long-term reliability concerns.

A Motorsport-Grade Solution

The HCE Battery Hold Down + Disconnect Switch isolates the battery completely from parasitic draw with a robust, high-current disconnect—preserving battery life during long-term storage while maintaining OEM-level reliability when switched on.

Designed and built by a race-winning team of mechanical engineers and industrial designers, every component in the kit is selected and manufactured to exceed factory standards.

“This isn’t just a disconnect switch—it’s a fully integrated, motorsport-grade system,” said HCE Performance. “From cabling to finishes, we engineered every detail to look factory, install easily, and perform under real racing and street conditions.”
