Salty Marine Complete Power Packages

Engineered to power every major marine gyro stabilizer — Seakeeper, Dometic DG3, Quick, Smart Gyro, and all DC-native stabilization platforms. Sodium-ion, lithium, and hybrid architectures.

The Gyro Power Problem

Every marine gyro stabilizer — regardless of brand — has one common requirement: clean, stable, high-capacity DC power. The failure mode is almost never the gyro itself. It is the power system supporting it: undersized batteries, incorrect chemistry, insufficient charging capacity, or voltage sag under load.

Engineering Fact: Our analysis of 1,247+ vessels found that 71% of gyro "malfunctions" were actually power system failures — not equipment defects. The gyro was fine. The batteries, alternators, or wiring were not.

Salty Marine complete packages solve this by designing the entire power ecosystem around the specific demands of your chosen gyro — whether that's a Seakeeper SK26, a Dometic DG3, a Quick unit, or a Smart Gyro stack.

Universal Gyro Compatibility

Salty Marine packages are engineered for compatibility with all major gyro brands. Our power architecture does not discriminate by manufacturer — we size, spec, and deliver for your specific unit.

Gyro Brand Typical DC Input Salty Marine Package Notes
Seakeeper (SK2–SK40) 12V, 24V, or 48V HLMCS-II / III / IV Model-specific voltage; high inrush at startup
Dometic DG3 12V, 24V, or 48V DC HLMCS-III / IV Native DC; lowest power draw in class
Quick Gyro 24V or 48V DC HLMCS-III / IV Stable draw; magnetic bearing sensitive to ripple
Smart Gyro Auto-sensing 12/24/48V HLMCS-III / IV / V Flexible voltage; scales with module count
Kenettic / Offspirm 12V or 24V DC HLMCS-II / III Verify published specs with independent test
VEEM Gyro Typically 24V or 415V AC HLMCS-IV / V + Inverter Commercial units may need AC inversion

Complete Power Packages

Each package includes batteries, BMS, charger/inverter integration, cabling, and structural battery trays. Everything engineered as a system — not a collection of parts.

Why Sodium-Ion? Salty Marine's sodium-ion chemistry delivers lithium-like energy density with superior thermal stability, zero thermal runaway risk, and full recyclability. For marine applications where safety and temperature tolerance matter, sodium-ion is the engineering choice. See our sodium-ion case study.

What's Included in Every Package

Unlike battery-only vendors, Salty Marine complete packages include the full integration stack:

Battery & BMS

Engineered cell configuration matched to your gyro's voltage, inrush current, and continuous draw. BMS programmed with gyro-specific load curves — not generic automotive profiles.

Charger & Inverter

Marine-grade charger sized for recovery within your typical between-trip window. Inverter integration for AC-powered accessories without separate systems.

Cable & Protection

Correctly sized AWG cabling with marine lugs, heat shrink, and chafe protection. ANL or Class T fusing with gyro-appropriate trip curves.

Structural & Monitoring

G10 or aluminum battery trays engineered for vessel motion and G-force. Optional remote monitoring with low-voltage and temperature alerts.

The SGH Integration Advantage

Because Salty Marine, UpgradeGyro, and Starboard Yacht Group share a common engineering intelligence backbone, our packages are designed with full knowledge of how gyros actually behave in the field — not just in manufacturer spec sheets.

Real-World Intelligence: Our 1,247+ vessel database includes power system failure forensics from Seakeeper, Dometic, Quick, Smart Gyro, and emerging brands. Every Salty Marine package incorporates lessons learned from actual field failures — not just theory.

Package Add-Ons

  • Solar Regeneration: 400W–1,200W marine solar array with MPPT for dockside trickle charging
  • Generator Auto-Start: Low-voltage trigger to start onboard generator before gyro shutdown
  • Interceptor Power Bus: Dedicated bus for Humphree/Zipwake systems to prevent voltage sag
  • 24/7 Monitoring: Cellular-connected BMS telemetry with SMS alerts
  • Emergency Backup: Compact lithium jump pack for critical gyro restart
