Key Features

12V Sodium-Ion Car Audio Battery TechnologyAdvanced sodium-ion chemistry delivers dependable voltage stability, fast discharge capability, and improved thermal performance for modern car audio systems.
4200W5000W Peak Pulse Capability Per BatteryEngineered to support high-output audio systems in the 4200W5000W range during short-duration burst demand when paired with a properly upgraded electrical system.
13.5Ah / 162Wh CapacityCompact high-performance power storage engineered for amplifier support and supplemental electrical stability.
Holds Voltage Stiff Under LoadMaintains 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 LifeRated for 10,000+ full-power pulse cycles, roughly 200,000 bass hits, while still retaining 90% of original capacity.
All-Weather PerformanceSuperior low-temperature behavior with cold-weather support down to -29C, where lead-acid and lithium packs struggle.
Safer ChemistrySodium-ion cells are inherently more stable than lithium and far more resistant to fire and thermal runaway, even under abuse testing.
Compact Lightweight DesignOnly 6 lbs with a space-saving footprint that simplifies installation in amplifier racks, custom battery banks, and tight vehicle layouts.
Side-Mounting CapableThe sealed sodium-ion design allows the battery to be safely mounted upright or on its side for greater installation flexibility.
Long Service LifeEngineered 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.
