This battery is a Lithium Iron Phosphate (LiFeP04/LFP). Down4sound's JP40 is the most powerful LFP for its size in the car audio industry.

      • JP40 Battery Size is 10.5 inches long, 8.25 inches wide, and 3 inches tall. Weighing in at 14 pounds.
      • The JP40 is the first car audio lithium battery with an integrated voltage and temperature monitoring and notification system. We are taking the guesswork out of the picture.
      • The JP40 also features a compact LOW profile & infinitely expandable car audio lithium battery. The JP40 shares a similar look to JP Amplifiers with its Sleek machined aluminum housing, allowing rapid heat dissipation; a bonus is that's it is easily mountable.

No voltage boosting necessary- DO NOT EXCEED 14.8v as this will cause damage to the battery.

      • Onboard balancing 

Aluminum housing isolated from ground to reduce the risk of short if 12V power accidentally contacts the battery housing.
