High-Performance Features
The XS Power SB75-20Q is a 12V super capacitor bank designed for Group 20 configurations, featuring a substantial 75 Farad capacitance and a maximum power output of 600W, making it an ideal and efficient solution for enhancing power delivery in various 12V electrical systems.
Frequently Asked Questions (FAQ)
- • Why doesn't my SB75-20Q behave like a regular battery?
The SB75-20Q is a 75-farad SuperBANK, not a conventional battery. It is designed to provide rapid bursts of electrical energy and voltage stabilization rather than store large amounts of energy for long periods. Its energy rating is only 4.08Wh.
- • My Group 20 battery tray is tight—will the SB75-20Q actually fit?
The SB75-20Q follows the BCI Group 20/20L format and measures approximately 6.89 × 3.43 × 6.1 inches. Check the actual tray dimensions, hold-down, terminal location, and cable reach before installation rather than relying only on the group number.
- • Why does the capacitor bank seem to discharge so quickly?
The SB75-20Q is designed for short-duration power assistance. With only 4.08Wh of stored energy, it can deliver high current briefly but cannot replace the energy capacity of a conventional battery during prolonged loads.
- • Can I connect the SB75-20Q directly to my 12V electrical system?
It is a 12V SuperBANK with a published operating voltage range of 12.0–16.2V. However, charging through an alternator or stator should keep a 12V system around 13.8–14.0V according to XS Power's installation guidance.
- • Why did I get a spark when hooking up the SB75-20Q?
A discharged SuperBANK can draw a large initial current when connected to a powered electrical system. That inrush can produce a noticeable spark, so the charging and connection procedure should be followed carefully rather than treating the unit like an ordinary battery.
- • Is 600 watts the amount of power the SB75-20Q can supply continuously?
No. 600W is the manufacturer's maximum power rating, while the bank is also rated for up to 1,500A. These figures describe its high-current capability and should not be interpreted as continuous energy capacity.
- • Why are my cables difficult to attach to the SB75-20Q?
The SB75-20Q uses M6 terminal hardware rather than conventional automotive battery posts. If the factory cable ends do not match the threaded terminals, appropriate hardware or adapters may be needed for a secure connection.
- • What should I check if the SB75-20Q doesn't improve voltage dips?
First inspect the alternator or stator output, battery condition, cable size, grounds, and terminal connections. A SuperBANK can help with rapid current demand, but it cannot compensate indefinitely for an undersized charging system or excessive sustained electrical load.
- • Can I leave the SB75-20Q connected while the vehicle is stored?
If the bank remains connected, any parasitic electrical load can affect the overall system. Before long-term storage, verify the manufacturer's discharge and storage procedure and make sure the SuperBANK cannot accidentally remain energized or exposed to unsafe conditions.
- • What if my SB75-20Q develops a problem and the warranty is needed?
Keep your purchase information and installation details. The current XS Power listing specifies a 1-year warranty, while some online retailers advertise different warranty periods, so confirm the warranty terms applicable to the seller you purchase from.
