Maxwell 16V 500F Supercapacitor Car Engine Start Module
Maxwell 16V 500F Supercapacitor Car Engine Start Module
Maxwell 16V 500F Supercapacitor Car Engine Start Power Module
Upgrade your vehicle's starting reliability with the SUYIJIA Maxwell 16V 500F Super Farad Capacitor module. Engineered with ultra-low internal resistance and a high-capacity 500-Farad supercapacitor cell, this unit delivers a burst discharge current of at least 2,000 amperes — enough to fire up engines with up to 3.0L displacement, even in cold-weather conditions. No conventional battery charging required; the capacitor charges rapidly and is ready to go when you need it most.
CE-certified and built with a fully integrated protection board, this module features a built-in voltage display so you can monitor status at a glance. Available in two compact form factors to suit different engine bay layouts.

Frequently Asked Questions
Q: What is a 16V 500F supercapacitor and how does it help with car engine starts?
A: A supercapacitor (also called a super farad capacitor) stores and releases electrical energy very rapidly. The Maxwell 16V 500F module can deliver a burst of 2,000+ amperes, providing the powerful surge needed to crank and start a vehicle engine — including engines up to 3.0L displacement — quickly and reliably, even in cold conditions.
Q: What is the difference between the single-row and double-row configurations?
A: Both configurations offer the same electrical performance (16V, 500F). The single-row (elongated) unit measures 37 cm × 6 cm × 17 cm, while the double-row (square) unit measures 19 cm × 14 cm × 12 cm. Choose the layout that best fits your vehicle's available engine bay space. Both come fully equipped with a protection board and voltage display.
Q: Does this supercapacitor module replace my car's main battery?
A: No. The Maxwell 16V 500F supercapacitor module is designed to work alongside your existing battery as a starting power supplement and stabilizer. It helps reduce the load on your factory battery, can extend its service life, and provides rapid-discharge energy for engine ignition.
Q: Is this module compatible with audio systems?
A: Yes. In addition to supporting engine starts, the supercapacitor module helps stabilize the vehicle's electrical system voltage, reducing electromagnetic interference and improving the overall sound quality of your car audio setup.
