150F SuperBANK – 3,000A Power Reserve
Add extra power support to demanding electrical systems with the XS Power SB150-975L 12V Super Capacitor Bank. Its 150F capacity, 3,000A maximum current, and 1,200W output provide a compact energy solution for performance-focused applications.
Frequently Asked Questions (FAQ)
- • Why does the SB150-975L need to be charged before installation?
A real SuperBANK user reported that the initial charge took about 1 hour and 10 minutes before the capacitor was ready for use. This shows why installation should be planned ahead instead of expecting the unit to be immediately ready out of the box.
- • Can the SB150-975L stop bass hits from pulling voltage down?
One XS Power SuperBANK user reported voltage dropping into the low 12V range when heavy bass hit, then staying around 13.6V after adding a SuperBANK. The SB150-975L is designed for the same type of short-duration current support, with 150F capacitance and up to 3,000A maximum current.
- • Why does the SuperBANK voltage fall after the music stops?
A user who tested an XS Power SuperBANK with the vehicle turned off noticed that its voltage eventually returned to the battery’s resting level of roughly 12.6V. This is normal capacitor behavior—the bank supplies stored energy during demand rather than acting like a large reserve-energy battery.
- • Is the SB150-975L really useful with a factory-size alternator?
One owner reported using an XS Power SuperBANK with an 80A factory alternator and a small lead-acid battery while running a powerful audio system. They found the capacitor reduced voltage stress enough that they did not immediately need a higher-output alternator.
- • Why did a user notice the charging cable getting warm?
During one real-world SuperBANK installation, the owner reported that a 2-AWG charging wire became warm while finishing the charge directly from the battery. This is a good reminder to follow the manufacturer's charging procedure rather than improvising the final charging connection.
- • Can the SB150-975L replace the vehicle’s main battery?
No. XS Power describes SuperBANKs as devices that work alongside a battery to provide rapid current during demand spikes. The SB150-975L has only about 4.68Wh of stored energy, so it should not be treated as a conventional battery replacement.
- • Why might the SB150-975L seem less effective with constant heavy bass?
A SuperBANK owner reported that dynamic bass hits were handled very well, but continuous modern bass tracks slowly brought the voltage down over time. This highlights an important limitation: the SB150-975L can assist with short bursts, but sustained electrical demand still has to be supplied by the vehicle's battery and charging system.
- • What happens if the SB150-975L is connected backward?
Reverse polarity is a serious installation risk. XS Power specifically warns users to verify polarity every time the SuperBANK is connected, making correct positive and negative identification essential before applying power.
- • Can moisture cause trouble with an SB150-975L installation?
Yes, environmental exposure is an installation concern. XS Power recommends protecting the SuperBANK from direct water spray, corrosive environments and unnecessary exposure, while also recommending anti-oxidation protection on terminal connections.
- • Why can the SB150-975L make a car-audio system feel more stable without adding another battery?
A SuperBANK user reported that voltage previously fell into the 12V range during hard bass hits but remained substantially more stable after installation. The SB150-975L is built for this rapid-response role, offering 150F capacitance, 3,000A maximum current and a compact 4-lb package.
