Key Features

• 12V Sodium-Ion Car Audio Battery Technology
  Advanced sodium-ion chemistry delivers dependable voltage stability, fast discharge capability, and improved thermal performance for modern car audio systems.
• 4200W–5000W Peak Pulse Capability Per Battery
  Engineered to support high-output audio systems in the 4200W–5000W range during short-duration burst demand when paired with a properly upgraded electrical system.
• 13.5Ah / 162Wh Capacity
  Compact high-performance power storage engineered for amplifier support and supplemental electrical stability.
• Holds Voltage Stiff Under Load
  Maintains a voltage floor above 10.4V through a full 3-second 400A burst, keeping amplifiers out of protect mode and your output clean.
• Massive Cycle Life
  Rated for 10,000+ full-power pulse cycles, roughly 200,000 bass hits, while still retaining 90% of original capacity.
• All-Weather Performance
  Superior low-temperature behavior with cold-weather support down to -29°C, where lead-acid and lithium packs struggle.
• Safer Chemistry
  Sodium-ion cells are inherently more stable than lithium and far more resistant to fire and thermal runaway, even under abuse testing.
• Compact Lightweight Design
  Only 6 lbs with a space-saving footprint that simplifies installation in amplifier racks, custom battery banks, and tight vehicle layouts.
• Long Service Life
  Engineered for dependable cycle life and long-term durability in demanding mobile audio environments.

Real-World Performance

Verified engineering figures under real-world load:

• The Competition Burp: Under a 400A (30C) load the DNA-13 holds a voltage floor above 10.4V through a full 3-second burst, delivering roughly 4,200 watts of sustained pulse power and keeping your amplifiers out of protect mode.
• Music & Cruising: Under dynamic music loads around 200A (15C) the battery holds near its 12.0V nominal, supplying roughly 2,400 watts of clean sustained power so your amps run cooler and cleaner than on a sagging lead-acid system.
• Built To Last: Cycled 10,000+ times at full 4,200W pulse discharges, a competition-grade workload, and the DNA-13 still holds above 90% capacity.

Discharge Ratings (Nominal @ 12V)

Charging Support

Maximum recommended alternator: 200 A. Car audio is a pulse-charging application, current flows in bursts between bass notes rather than a constant sustained load.

Physical

Important Electrical System Information

Overall system performance depends heavily on the vehicle’s charging system and supporting electrical upgrades. Alternator output, charging voltage, amplifier efficiency, wiring quality, grounding, and overall electrical health all affect final performance capability and voltage stability.

• Big 3 upgrade strongly recommended
• High-output alternator recommended for larger systems
• Quality OFC power and ground wiring recommended
• Proper amplifier tuning and voltage monitoring required
• Actual performance will vary depending on charging system efficiency and overall electrical support

Charging Best Practices

• Daily Driving (Standard Use): Maintain a charging voltage between 13.8V and 14.8V. This range is compatible with most factory alternators and delivers reliable long-term performance with no special equipment.
• Competition Mode (Max Power): For dedicated competition or SPL work, charge up to 15.8V to unlock the maximum potential energy of the pack. 15.8V is the absolute limit, do not exceed. It is the user’s responsibility to verify their vehicle’s charging system capabilities.
• Cold-Weather Charging: Sodium-ion excels in the cold, but if the battery is below 0°C, reduce charging power to protect the internal chemistry.
• Hot-Weather Charging: Do not charge if the battery temperature exceeds 55°C (131°F). If the case feels extremely hot, allow it to cool before charging.
• Long-Term Storage: Store between -20°C and 45°C in a cool, dry place. Charge to roughly 12.0V every 3 months to maintain optimal health and prevent over-discharge.

Ideal Applications

• High-output car audio systems
• Amplifier voltage support
• Competition-style bass systems
• Custom battery banks
• Daily-driver and demo vehicle applications
• Compact high-performance electrical upgrades
