The TDA7492P amplifier module works fine on 12 volts. But will it work on three 2.5V supercapacitors in series?

    Oh. And turn up the tunes to drown out all the hecklers. Lol.

    Configure them for 12V and use a buck-boost converter to set the voltage to run the speaker.

    That way you can recharge the capacitor on the go from your car.

    hi hope you get this. is there a way to convert the volume buttons to some sort of rotary switch

    Complete noob to this, but I think I'm going to have to build myself one of those.

    How rapidly can the super capacitors charge with those balance circuits on? I'm planning an e-bike mod to have Re-Gen braking that have the caps power a buck/boost then into a charge module. What would you recommend?

    Fantastic, just get your solar panel attached to caps…
    Needs a bass speaker!👍

    Cool. Thanks 🙂

    I run one of these amps via a buck/boost regulator to give 21v,.. yes you will loose a little efficiency,.. but it will give stability to the amp. and it works a treat. Also when charging your super caps. 'assuming' a standard diode,.. then you should select 8.1 volts as your input charge level… to give you 7.5v distributed at the caps. terminals

    Add a mirror ball and roller rink and you're in business!
