VCP9K 9000W Audio System Charge Pump

VMAX Charge Pumps (VCP) are hybrid batteries designed to be installed in parallel with 12V batteries to improve and solve most of the problems associated with high-power audio systems and loads with high current surges in the same manner as stiffening capacitors. And just like capacitors, VCPs are also designed to be continuously recharged by the connected battery to deliver the high current surges needed by high-power audio systems. Yet the main advantage over capacitors is that the VCPs -acting as batteries- have larger capacities of 6ah-18ah, enabling them to deliver and sustain much longer power surges than the equivalent capacitors’ capacity of less than 0.4ah/100f.

Main Uses:

• Car Audio: 9,000 Watts
• Hydraulics
• High starting current inductive loads 

Advantages:

1. Maximize SPL levels and minimize vehicle light flickering: VCPs help maximize the sound pressure level (SPL) produced by audio systems and minimize light flickering by delivering massive current surges to meet the demands of vehicle electronics and audio systems.

2. Eliminate the need for large battery banks: By efficiently boosting and delivering high current surges, VCPs reduce the reliance on multiple batteries, saving space and cost.

3. Minimize system failures: Voltage drops can cause power amplifiers and subwoofers to underperform or fail. VCPs help mitigate this issue by ensuring that the voltage supplied to these components remains optimal, preventing performance degradation and potential failures.

4. Increase the lifespan of vehicle batteries: VCPs play a protective role by preventing the batteries from experiencing deep discharges, thereby increasing their lifespan.

5. Support motors, hydraulics, and inductive loads during startup: VCPs provide the necessary current surges for motors and other inductive loads to ensure smooth startup and operation.

Overall, VMAX Charge Pump devices offer various benefits, including improved power delivery, protection for components, increased efficiency, and extended battery lifespan. These make them valuable additions to systems that require high current surges and reliable power supply.

Installation

1. Preparation:
   • Read the unit’s technical data and specifications at vmaxtanks website before use.
2. Connection Setup:
   • Use the correct gauge cables and fuses to connect the VMAX Charge Pump (VCP) in parallel with the existing 12V battery or power source.
   • Securely mount and install the VCP using adequate screws.
   • Connect main battery cables to VCP terminals and use an inline fuse:
     • VCP6: 100A
     • VCP9: 100-150A
     • VCP12: 150A
     • VCP18: 200-250A
3. System Wiring:
   • After wiring, connect system/load cable ends to the VCP terminals.
   • Ensure all terminals are tight and secure (do not overtighten).
4. Fusing:
   • Fuse all power cables at VCP terminals:
     • VCP6: 150-200A
