⚡ At a Glance
  • Voltage Stability: Stores reserve energy for short bursts, smoothing voltage under load
  • Best for: Car audio enthusiasts running high-power amplifiers and bass-heavy systems
  • Not ideal for: Owners seeking integrated hands-free or speaker-level crossover functions

18 Farad capacitance with an extremely low ESR helps supply short-term current to amplifiers. Built-in voltmeter, remote connection and protection circuits simplify monitoring and safeguard the electrical system.


Consistent amplifier peaks - with 18 Farad capacitance and extremely low ESR

Equivalent series resistance is listed as <0.00195 ohm, allowing rapid charge and discharge cycles, while the large 18F capacity stores reserve energy for transient demands. Fast energy delivery supports amplifier current spikes without relying solely on the vehicle battery.

Maintains stable voltage during bass hits, reducing audible distortion and preventing power sag. Amplifiers can sustain output more reliably during short, high-current passages.

Electrical protection - with reverse polarity and over-voltage safety circuits

A reverse polarity protection circuit prevents damage if wiring is connected incorrectly, and built-in protection guards against exceeding the stated maximum voltage. Operating voltage is specified as 12V with a maximum input of 24 V.

Safeguards amplifiers and car electrics from common fault scenarios and voltage excursions. Peace of mind during installation and heavy use comes from those protection measures.

Easy monitoring and fitment - with red digital voltmeter and remote connection

A red digital voltmeter is fitted for direct readout and a remote connection is included for dash mounting of the display; overall dimensions are 25.30 x 9.00 x 5.00 cm with a black finish. Design emphasises compact installation in limited spaces.

Quick visual voltage checks make system tuning and troubleshooting faster. Remote display and compact size mean neat installations and accessible monitoring without removing the unit.
