Frequently Asked Questions (FAQ)


  • • Why does the XS Power SB500-65 need to be charged before I connect it?
    A new SuperBANK can draw a very large amount of current almost instantly when connected to a power source. XS Power provides a controlled charging method using the included lamp to limit the initial current and reduce the chance of sparks or damaged connection points.
  • • Can the SB500-65 solve voltage drops in a high-powered audio system?
    It can help reduce short-duration voltage dips caused by sudden amplifier demand. However, it should be connected alongside a properly sized battery and charging system rather than being expected to correct an undersized alternator or inadequate wiring. Users have reported noticeably steadier voltage and reduced headlight flicker after installation.
  • • What happens if I accidentally connect the SB500-65 with reversed polarity?
    Do not reverse the polarity. Incorrect positive and negative connections can cause serious electrical damage and create a dangerous situation. Always verify the terminals with a meter and follow the installation instructions before applying power.
  • • Can I use the SB500-65 with my existing AGM battery?
    Yes. The SB500-65 is designed to operate in parallel with lithium or AGM batteries, allowing the SuperBANK to provide additional energy during short, high-current demands.
  • • Why does my SB500-65 voltage change so quickly after heavy use?
    Unlike a conventional battery, a supercapacitor can charge and discharge very rapidly. After supplying power during a heavy demand, its voltage may change quickly as the vehicle's charging system replenishes the stored energy. This rapid recovery is part of the SuperBANK's intended operation.
  • • Is the Group 65 size enough to guarantee that the SB500-65 will fit my vehicle?
    No. Group 65 compatibility does not guarantee physical clearance in every battery compartment. The SB500-65 measures approximately 11.8 × 7.2 × 6.8 inches, so users should check the available tray space, terminal position, cables, and surrounding components before installation.
  • • Why is my SuperBANK getting hot during operation?
    Excessive temperature can indicate an electrical or installation problem, particularly if the unit is operated outside its specified conditions. The SB500-65 is rated for -40°F to 150°F, and XS Power warns that operation above 149°F/65°C can void the warranty.
  • • Can vibration cause problems with SB500-65 connections?
    Yes, especially in trucks, off-road vehicles, and other high-vibration applications. Loose mounting or electrical connections can create resistance and unreliable performance. XS Power recommends checking mounting fasteners and electrical connections for proper torque every six months in high-vibration applications.
  • • Why should I keep the SB500-65 away from direct water spray?
    The SuperBANK is an electrical energy-storage device, so direct splashes, water spray, and corrosive environments should be avoided. Protecting the unit and treating the terminal connections with an appropriate anti-oxidation product can help maintain reliable long-term performance.
  • • Can I disconnect the SB500-65 immediately after turning off the vehicle?
    No. The SuperBANK can retain electrical energy even after the vehicle is switched off. It should be properly discharged before removal or servicing to reduce the risk of sparks or electric shock. XS Power also notes that a discharged SuperBANK can naturally regain some voltage, so proper discharge procedures should be followed.
