Stetsom MiniVT Digital Voltmeter Mini Automotive Battery VT Blue LED

The Stetsom MiniVT Digital Voltmeter is an ultra-compact automotive voltmeter built for installers who demand reliable, real-time battery voltage monitoring for high‑performance car audio. It’s offered in a regular 7–30 Vdc version and a High Voltage variant up to 455 V, both with a blue LED and Remote Power for clean, secure integration.

• Voltage range (MINIVT Regular): 7–30 V DC — suitable for typical 12V car electrical systems and automotive audio installations that require monitoring across a common range.
• Current consumption: 15 mA — low draw ensures the voltmeter won’t significantly impact battery drain during extended monitoring.
• Standby consumption: 0.2 mA — nearly negligible current when the unit is not actively cycling readings, preserving system energy.
• Scale voltage: 7–30 V DC — defines the usable measurement window for accurate, real-world voltage reporting in standard automotive setups.
• Dimensions (Regular MINIVT): 1.89 x 0.79 x 0.31 inches — ultra-compact footprint ideal for tight dash or panel installations.
• Weight: 0.03 lb (12.8 g) — light enough to mount in small spaces without adding significant bulk.
• Remote Power: Provides power via a separate circuit for secure operation and convenient integration with your audio system and blue LEDs.
• LED color: Blue — high-contrast readout that remains legible in dark cockpit environments.
• Scale voltage (High Voltage MINIVT-HV): Up to 455 V (max) — enables monitoring of elevated voltage levels for high‑voltage or multi‑battery systems with individual sensing needs.
• Dimensions (MINIVT-HV): 2.1 x 1.8 x 0.31 inches — slightly larger footprint to accommodate HV circuitry while keeping a compact form factor.
• Weight: 0.05 lb (24 g) — a bit heavier due to HV components but still compact for dashboard or chassis mounting.
• Current consumption (HV): 15 mA (max.) — maintains efficient power use even at higher voltage monitoring ranges.
• Standby consumption (HV): 0.2 mA — ensures minimal drain when not actively reporting voltage.

The MINI VT is well-suited for automotive audio builds that require dependable voltage feedback across multiple batteries in high-voltage systems, with a tip suggesting individual monitoring per battery to optimize performance and protection.
