Antigravity VTX-20 — Lithium 16V Motorsports Battery

Ultra-light, high-power 16-volt racing battery in a compact YTX12 case.

The Antigravity VTX-20 16-Volt Lithium Battery delivers huge cranking power in the smallest, lightest package you’ll find for motorsports. Built for race vehicles that run 16V systems, the VTX-20 weighs just ~5.15 lbs and packs 500 Cranking Amps in a compact YTX12 case—ideal when every pound and every inch matters. Actual voltage is ~16.5V for a hot, reliable spark.

• Serious power-to-weight: ~5.15 lbs with 500 CCA-equivalent cranking performance.
• Compact footprint: YTX12 case size fits tight race bays and lightweight builds.
• Race-proven 16V output: stronger spark and faster starts for competition engines.
• Low self-discharge: can hold a charge up to a year (no parasitic drains present).
• Durable hardware: large all-brass terminals for secure, low-resistance connections.
• Cost-effective weight loss: drop up to ~28 lbs in race cars vs. typical lead-acid.

Features

• Ultra-lightweight, high-power LiFePO4 motorsports battery
• Most compact/powerful 16V lithium battery in its class
• Up to ~28 lb weight savings in race cars (~14 lb in motorcycles)
• Can hold a charge up to 1 year with no parasitic drains
• Large all-brass terminal design for robust, low-loss connections
• Suitable for vehicles using 16V systems (confirm application)

Best Uses

• Race vehicles using 16-volt electrical systems
• Excellent for dedicated race cars

Specifications

Usage & Charging

• Use only a 16V LiFePO4-compatible charger (CC/CV profile).
• Before storage, fully charge and disconnect parasitic loads (alarms, ECUs, trackers, etc.).
• Securely mount the battery; verify terminal torque and cable strain relief.

Recommended Pairing

For fastest, safest top-offs between sessions, pair with the Antigravity 16V Lithium Charger — 5A (110–230V AC, multiple protections, LED status with voltage/current screen).

FAQs

Will this work on my street car?
No. The VTX-20 is intended for race vehicles using 16-volt electrical systems.

How long can it sit between events?
Up to ~1 year if there are no parasitic drains. Disconnect or manage accessories that pull current when parked.

Which charger should I use?
A dedicated 16V LiFePO4 charger only (e.g., Antigravity 16V 5A). Do not use 12V chargers.
