XS Power SB500-51R 500F SuperBANK – 10,000A High-Output Energy Reserve

Boost your high-demand electrical system with the XS Power SB500-51R SuperBANK, a Group 51R 12V super capacitor bank engineered for rapid energy delivery. With 500F capacitance, 10,000A maximum current, and 4,000W maximum power, it provides strong performance for demanding automotive applications.

 


Frequently Asked Questions (FAQ)


  • • Why does the SB500-51R still need my main battery?
    The SB500-51R is designed to work in parallel with an AGM or lithium battery, not simply replace the vehicle's primary energy storage. Its 500-farad capacity is intended to provide fast bursts of power when the electrical system suddenly demands more current.
  • • Why isn't my SB500-51R helping much with continuous bass?
    A common misunderstanding is treating a supercapacitor like a second high-capacity battery. The SB500-51R stores 18.2 Wh, so it can respond quickly to short power peaks but cannot supply a heavy load indefinitely without the battery and alternator supporting the system.
  • • Why are the terminals on my SB500-51R positioned differently than expected?
    This model uses a Group 51R reverse-terminal configuration. If your vehicle normally uses a standard Group 51 battery, check the positive and negative terminal positions before installation so the existing cables can reach correctly.
  • • Can I connect the SB500-51R straight to my battery when it is completely discharged?
    It should not be connected without following the required charging procedure. XS Power specifies a controlled charging range, and JEGS notes that 12V models charged by a stator or alternator should be charged between 13.8 and 14.0 volts.
  • • Why did my installation become difficult even though it is called a Group 51R?
    Group designation does not guarantee that the unit will physically fit every factory battery tray. The SB500-51R measures about 9.04 × 5.43 × 8.19 inches and weighs 11 pounds, so clearance around the case, terminals, and cables should be checked first.
  • • Why does the SuperBANK require more safety precautions than a normal capacitor?
    The SB500-51R can handle up to 10,000 amps and stores substantial electrical energy. XS Power warns that residual voltage can remain at the terminals, so the unit must be properly discharged and checked with a calibrated meter before handling.
  • • Why shouldn't I mount the SB500-51R somewhere exposed to water?
    The installation guidance recommends protecting the SuperBANK from direct splashes, spray, and corrosive environments. If the unit experiences significant cycling, free-air mounting or forced ventilation is also recommended.
  • • Why are there so few detailed customer reviews for this exact model?
    Public feedback for the SB500-51R is relatively limited. Several current retailers, including Down4Sound, Showtime Electronics, and Car Audio Bargain, show zero reviews, while Autoplicity has older customer feedback that is largely about purchasing rather than technical installation performance.
  • • What if my voltage is still unstable after installing the SB500-51R?
    The SuperBANK should not be used to hide problems elsewhere in the electrical system. Check the alternator's output, battery condition, cable size, grounds, terminal connections, and amplifier demand before assuming the SuperBANK itself is defective.
  • • Is the SB500-51R a good choice if my vehicle has the reverse-terminal layout?
    It can be a convenient match when the vehicle requires a Group 51R configuration, while its 500-farad capacity and 4,000-watt maximum power rating make it aimed at high-demand applications. However, physical fitment and the complete charging-system requirements should still be verified before installation.
