Hilfe! Probleme mit 2x10 Watt Verstärker

Beitragvon CONRAD » 10.03.2015, 16:59

Hallo zusammen,

ich mache in der 8. Klasse eine Solar-Projekt, bei dem ich eine kleine "Disco" mit Lichtorgel, Minispiegelkugel, Blink-LED usw. baue. Außerdem soll ein kleiner Verstärker eingebaut werden, der ein Audiosignal von beispielsweise einem Handy verstärken soll. Der Clou bei diesem Solar-Projekt ist, dass es eben auch mit Solarstrom betrieben wird, der in Akkus gespeichert wird.

Mein kleiner Stereo-Verstärker hat 2x10 Watt und läuft mit 6-18 Volt. Mit einem Netzteil mit 9 Volt und 600mA läuft dieser nahezu unverzerrt, aber mit den Akkus (acht mal 1,2 V = 9,6 V und zusammen 800mA) läuft er nur kurz und wird dann immer leiser, bis er ganz ausgeht.

Ich freue mich auf Unterstützung. :D

Als Verstärker hab ich diesen hier genommen:
und die Akkus haben 2100 mAh. Wenn ich alle acht in Reihe schalte, messe ich 800 mA.

Mich wundert trotzdem, dass das Netzteil mit gemessenen 600 mA dann diese Leistung aufbringen kann :?:

Trotzdem danke für den Tipp und die Idee mit dem Bleiakku. :idea:
