2.7V 120F / 16V 20F Supercapacitor Module Kit | DIY Start Power

## Build Your Own Starter Power Supply

This kit gives you a ready-to-use supercapacitor bank for DIY projects: six
2.7V 120F super farad cells wired in series to form a 16.2V, 20F module.
Connect it in parallel with a 12V battery or use it as the energy core of a
custom jump starter, and you get an instant burst of current that a battery
alone can't deliver.

### Small Footprint, Serious Punch

At just 72 × 45 × 50mm, the module takes up less space than a pack of cards.
The upright layout makes it easy to mount against a wall, inside a compact
enclosure, or in a tight engine bay where a long flat bar won't fit.

### Why Supercapacitors for Starting

- **Instant discharge** – delivers the surge current a starter motor demands
- **Cold-weather ready** – works down to -40°C where lead-acid batteries fade
- **Long life** – rated for 500,000+ charge/discharge cycles
- **Charges in seconds** – no long wait, no memory effect
- **Maintenance-free** – no acid, no fluid, no servicing
