The high-performance, high-rpm charging system. 300 watts.

It fits behind a billet electric-start flywheel.

High-rpm charging

Full charge, all the way up.

Watch the meters as the engine sweeps from idle to past 8,000 rpm.

Demo — a picture of how the system charges, not a measurement.

What it is

A charging system, not a trickle.

No. I

300 watt system

A 300 watt charging system for small engines.

No. II

Built for high rpm

Full output from about 4,000 rpm, and it holds there as the engine keeps climbing.

No. III

Fits behind a billet flywheel

It fits behind a billet electric-start flywheel. It brings its own magnets, so it does not need a cast-iron flywheel.

No. IV

Three-phase, smooth DC

Three phases make near-flat DC that batteries, EFI and electronics like.

No. V

Series regulator

A series-type regulator holds the battery voltage steady.

No. VI

Robotics-class motor

A frameless robotics-class motor on a billet aluminum hub.

No. VII

Pull start stays

Nothing goes on the fan cover. Your recoil stays where it is.

No. VIII

Small block or big block

One kit, with a hub for small-block or big-block engines.
