We proudly introduce an industry first “drop-in kit” pairing a CNC Machined Billet Battery Mounting Kit with a Lithium Battery by Full Spectrum Power, designed for automotive applications.

Enthusiasts know that in the Racing and Competitive Street/Strip marketplace, winning races can come down to fractions of seconds, inches, and ounces. 

Through extensive research, Valkyrie Engineering has identified that both OEM (Original Equipment Manufacturer) and modified race vehicles are disadvantaged in gross vehicle weight because of industry-standard bulky and weighty OEM-sized batteries. Intending to reduce weight for improved vehicle performance, Valkyrie Engineering has designed a light-weight, compact battery mounting solution paired with the advanced Full Spectrum Lithium Battery as a kit, significantly reducing overall weight by 80% and product footprint by 50% while exceeding the required battery cranking amps like their oversized counterparts.

Our latest innovation is a drop-in Valkyrie CNC Machined Billet Battery Mounting Kit paired with a Full Spectrum Power P.12SX Lithium Battery.
