The ANT PWM Regulator Board (no pot on the board, must be purchased separately)
Big Al's new ANT board may be tiny, measuring only 23.5mm x 14.5mm, but it has giant features! Working with batteries from 2s up to 6s, this board uses Silent PWM™ Technology, has a built-in Voltmeter switch (so the Voltmeter can display either the output or the battery voltage) and reverse-polarity protection. The ANT has a completely new Timerless PWM circuit that makes it more reliable and more compact than any PWM circuit on the market. Maximum recommended current 40A.
