This Listing Includes: (1) Down4Sound DNA-13 13.5Ah 12V Sodium-Ion Car Audio Battery
The Down4Sound DNA-13 is a compact 12V sodium-ion battery built for car audio. It stores 13.5Ah (162Wh) and is rated for 202A continuous and 400A for a full 3-second burst, which Down4Sound measures at roughly 4,200 watts while the battery holds above 10.4V. Under everyday music loads around 200A it stays near its 12.0V nominal, supplying about 2,400 watts of clean power. At only 6 lbs, it fits easily in amplifier racks, custom battery banks and tight installs, and its sealed design can be mounted upright or on its side.
Features
- Rated for 10,000+ full-power pulse cycles while retaining 90% of original capacity
- Cold-weather support down to -29°C
- Sodium-ion chemistry that Down4Sound rates as more resistant to fire and thermal runaway than lithium
- Side-mounting capable sealed design
- Charges at 13.8–14.8V for daily driving, up to 15.8V for competition use
