An ideal treatment for 12v car audio lithium battery wonders is here now! This may help people who both do and dont have a top amperage custom alternator. NOTE that having an upgraded electrical with a top output alternator may benefit the JP 40 - 12v car audio lithium battery but is not needed. This 12v car audio lithium battery is good between 6000w thru 12,000w systems.

Wattage rating varies widely depending on alternator input ( 6000-12000W)
USE ONLY INSIDE OF VEHICLE. (Do not use under the hood or beyond vehicle. DO NOT use with any other form of batteries including different lithium chemistries and any lead acid or AGM batteries)

Example:
 

• 120-160A alternator - 6,000w rating
• 240-270A alternator - 8,000w rating
• 320-370A alternator - 10,000w rating
• Single 450A Alternator Or Dual 240+a alternators - 12,000w rating

This battery is really a Lithium Iron Phosphate (LiFeP04/LFP). Down4sound's JP40 is the most powerful LFP because of its size in the vehicle 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 very first car audio lithium battery having 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 the same check out JP Amplifiers using its Sleek machined aluminum housing, allowing rapid heat dissipation  12v car audio lithium; a plus is that's it's easily mountable.

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

 

• Onboard balancing

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

SPECIAL INSTRUCTIONS FOR THIS PRODUCT
This device includes a metal housing. The metal housing can be used to wick away heat generated by the
lithium cells under high load to help keep them cooler and to allow them to operate at higher efficiency. Metal also
conducts electricity and requires added safety considerations when using this product. This battery is
meant to be properly mounted before use. If the battery is not mounted it's easy for the battery to
shift during use and it may come into contact with metal causing a quick to the battery. Extra care must
be taken when attaching ring terminals, bus bars, and other attachment. The insulated area around the
terminals and the safety bar involving the terminals make accidental shorts much less inclined to occur.
Make certain all wires and connections in the vicinity of the battery are properly insulated to avoid any
accidental shorts.
