Frequently Asked Questions (FAQ)


  • • Can the SB500-34 make a noticeable difference in a car audio system?
    Yes. Owners have reported stronger system performance and reduced voltage drop after installing the SB500-34. One customer specifically said their two amplifiers were getting the power they needed and that the system sounded stronger afterward.
  • • Does the SB500-34 need another battery to work properly?
    Not necessarily, but many real-world installations use it alongside an AGM or lithium battery. XS Power describes the SB500-34 as a supercapacitor bank that can be connected in parallel with AGM or lithium batteries, while one owner reported using it with another Group 31 battery and achieving zero voltage drop.
  • • Can the SB500-34 fit in a factory Group 34 battery location?
    Users have reported that it can fit very well in a stock Group 34 location. One owner specifically said the unit fit perfectly in the factory battery position while providing additional electrical support.
  • • Why does the SB500-34 have a different connection setup than a normal battery?
    The SB500-34 uses M6 terminal hardware, which can require different connection hardware from a conventional automotive battery. This is an important installation detail for owners expecting standard battery posts.
  • • Can the SB500-34 help with voltage drop when an amplifier hits hard?
    This is one of the main reasons owners choose it. Multiple users report reduced or eliminated voltage drop during demanding audio use, including one customer who said the unit solved their voltage-drop problem and another who reported zero voltage drop after installation.
  • • Is the SB500-34 useful for engine starting, or is it only for car audio?
    It can also provide short bursts of starting power. XS Power explains that the SuperBANK can deliver a rapid energy surge during cranking and then recharge quickly, making it useful for starting applications as well as high-demand electrical systems.
  • • What happens if the SB500-34 is completely discharged?
    This is a concern raised by users discussing supercapacitor starting systems. A forum discussion specifically questioned the high initial current that could occur when a discharged SB500-34 is connected to another power source. The concern highlights why proper installation and charging procedures are important.
  • • Can the SB500-34 be used with lithium batteries?
    Yes. XS Power states that the SB500-34 can be connected in parallel with lithium or AGM batteries. An actual owner also reported using the SuperBANK together with sodium-based batteries and experiencing less voltage drop during startup.
  • • Is the SB500-34 too large or heavy for a performance build?
    Despite being a supercapacitor bank, it weighs about 11 pounds and measures approximately 10.24 × 7.2 × 6.75 inches. Users generally praise its compact Group 34 footprint, but its physical weight and mounting space should still be considered before installation.
  • • Can the SB500-34 replace a high-output alternator?
    Some owners report excellent results without adding another alternator, including one customer who said the SB500-34 eliminated voltage drop without needing an extra battery or high-output alternator. However, forum discussions point out that the correct electrical solution depends on the vehicle and system load, so the SuperBANK should not automatically be treated as a substitute for inadequate charging capacity.
