Description

The VMAX Charge Pump VCP9K is a cutting-edge 14.4V lithium-titanate oxide (LTO) battery engineered to revolutionize your car audio system. Unlike traditional capacitors or bulky secondary battery banks, the VCP9K acts as a charge pump, working in parallel with your existing 12V battery to deliver massive, instantaneous current surges when your system demands it. This ensures stable voltage, maximizes sound pressure levels (SPL), and eliminates light flickering, all while protecting your amplifiers and subwoofers from damaging voltage drops. The VCP9K's advanced LTO technology offers rapid 10C charging, high voltage tolerance (up to 17.4V), and an incredibly long cycle life of over 20,000 cycles. Its compact size and light weight make installation simple, and it's compatible with AGM, Gel, Wet, and other lithium batteries. Say goodbye to dimming headlights and distorted sound – the VMAX Charge Pump VCP9K is the ultimate power upgrade for serious car audio enthusiasts.
