This 16V 20F super capacitor module steps in exactly when you need it: it stores energy and releases it in one massive, instant burst, giving your starter motor the punch it needs to turn a cold engine over.\u003cbr\u003e\n\u003cbr\u003e\nUnlike batteries, capacitors don't slow down in winter. They work from -40°C, charge in seconds, and can be discharged and recharged hundreds of thousands of times without wearing out.\u003cbr\u003e\n\u003cbr\u003e\n### Why This Module\u003cbr\u003e\n\u003cbr\u003e\n**Built from 2.7V 120F cells**\u003cbr\u003e\nSix premium 2.7V 120F supercapacitor cells connected in series give you a 16.2V bank with 20F total capacitance — the right balance of voltage and stored energy for 12V vehicle systems.\u003cbr\u003e\n\u003cbr\u003e\n**Instant high-current discharge**\u003cbr\u003e\nDelivers the surge current a starter motor demands, reducing the load on your main battery and helping it last longer.\u003cbr\u003e\n\u003cbr\u003e\n**Cold-weather reliable**\u003cbr\u003e\nPerforms where chemical batteries struggle. Ideal for winter, for vehicles that sit for long periods, and for cars, motorcycles, boats, and generators kept in unheated garages.\u003cbr\u003e\n\u003cbr\u003e\n**Long service life**\u003cbr\u003e\nRated for 500,000+ charge\/discharge cycles — far beyond any lead-acid battery. No acid, no maintenance, no memory effect.\u003cbr\u003e\n\u003cbr\u003e\n**Compact DIY-friendly size**\u003cbr\u003e\nAt just 120 × 62 × 20mm, the module fits easily into tight engine bays, audio enclosures, or custom builds. Pre-configured, ready to wire in.\u003cbr\u003e\n\u003cbr\u003e\n### Specifications\u003cbr\u003e\n\u003cbr\u003e\n| Item | Specification |\u003cbr\u003e\n|---|---|\u003cbr\u003e\n| Rated voltage | 16V (16.2V max) |\u003cbr\u003e\n| Total capacitance | 20F |\u003cbr\u003e\n| Cell configuration | 6 × 2.7V 120F in series |\u003cbr\u003e\n| Cell type | Supercapacitor \/ ultra capacitor |\u003cbr\u003e\n| Module size | 120 × 62 × 20 mm |\u003cbr\u003e\n| Operating temperature | -40°C to +65°C (typical) |\u003cbr\u003e\n| Cycle life | 500,000+ cycles |\u003cbr\u003e\n| Applications | Cold start assist, car audio power support, DIY electronics, solar\/backup power |\u003cbr\u003e\n\u003cbr\u003e\n### What's in the Box\u003cbr\u003e\n\u003cbr\u003e\n- 1 × 16V 20F supercapacitor module kit\u003cbr\u003e\n\u003cbr\u003e\n### Installation Notes\u003cbr\u003e\n\u003cbr\u003e\n- Connect in parallel with your vehicle's battery, observing correct polarity (+ to +, – to –).\u003cbr\u003e\n- A balancing \/ protection board is recommended for series capacitor banks to keep cell voltages even.\u003cbr\u003e\n- Discharge the module fully before handling or modifying.\u003cbr\u003e\n- Please confirm your vehicle's voltage and available space before ordering.","brand":"DIYMars","offers":[{"title":"16V 20F","offer_id":53517030457655,"sku":null,"price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/5562\/4503\/files\/57_466541e6-bd9f-40e0-8c55-7f0a40baaa45.jpg?v=1793841886","url":"https:\/\/www.diymars.com\/pt\/products\/16v-20f-supercapacitor-module-2-7v-120f-cells","provider":"DIYMars","version":"1.0","type":"link"}
