SB500-34R 500F Group 34R SuperBANK – 4,000W

Upgrade your high-demand electrical system with the XS Power SB500-34R 12V Super Capacitor Bank. Built in a Group 34R format, it combines 500F capacitance, up to 10,000A of current, and 4,000W of maximum power for applications requiring substantial energy support in a compact package.

 


Frequently Asked Questions (FAQ)


  • • Why is my SB500-34R still showing voltage drops even after installation?
    The SB500-34R can help reduce voltage fluctuations, and one verified user specifically reported that it eliminated their voltage-drop concerns. However, it cannot compensate for an undersized alternator, weak wiring, or an electrical system that cannot supply the required current.
  • • Does the SB500-34R replace my regular AGM or lithium battery?
    No. The SuperBANK is designed to work alongside an AGM or lithium battery, supplying rapid bursts of current when demand suddenly increases. It should not automatically be treated as a conventional battery replacement.
  • • Why does the SB500-34R require a special charging procedure?
    A supercapacitor bank behaves differently from a conventional battery. When charging the SB500-34R from an alternator or stator, XS Power specifies 13.8–14.0 volts for 12V models. Using an unsuitable charging voltage can result in an improper installation.
  • • What is the biggest mistake people make when installing a used SB500-34R?
    One real-world discussion involving a used SB500-34R highlighted uncertainty about how to safely charge and initialize a supercapacitor bank. Users discussed the need for a controlled charging method rather than simply connecting it without understanding the procedure.
  • • Why does the SB500-34R have reverse terminal positioning?
    The 34R designation indicates a Group 34R configuration with reverse terminal orientation. This can make the unit suitable for vehicles designed around that terminal arrangement, but buyers should verify cable reach and polarity before installation rather than assuming every Group 34 tray will be a direct match.
  • • Can a loose connection make the SuperBANK perform poorly?
    Yes. The SB500-34R uses M6 terminal hardware, so the cable connections must be properly fitted and securely tightened. A poor high-current connection can introduce resistance and prevent the electrical system from receiving the benefit expected from the SuperBANK.
  • • Why does my SB500-34R seem to charge extremely quickly?
    Rapid charging is one of the characteristics of supercapacitor technology. Unlike a conventional battery, the SB500-34R is designed for very fast energy transfer, which makes it useful for handling sudden electrical demands from high-powered systems.
  • • Can leaving the SB500-34R disconnected create a safety problem?
    Yes. The unit can retain electrical energy even after being disconnected. XS Power warns users to properly discharge the SuperBANK and verify it with a calibrated meter before handling the terminals. Touching charged terminals can cause severe shock or burns.
  • • Why isn't the 4,000-watt rating the same as having a 4,000-watt battery?
    The 4,000W figure represents the SuperBANK's maximum power capability, not 4,000 watts of stored energy. The SB500-34R has 500F of capacitance and approximately 18.2Wh of stored energy, so it is primarily intended to deliver high-current bursts rather than operate large accessories continuously for hours.
  • • What should I check if my SB500-34R does not improve my car-audio system?
    Start with the alternator output, charging voltage, cable sizing, grounding points, terminal connections, and amplifier demand. The SuperBANK can provide up to 10,000A of current capability, but the rest of the electrical system still needs to be capable of supplying and distributing power correctly.
