Ich war anfangs echt ein bisschen skeptisch, weil man im Netz ja viel zu hören bekommt, wenn es um Li-Polymer-Akkus geht. Aber der originale E66 Akku hier? Junge, Junge... das Teil ist ein Biest! Ich habe die Zelle jetzt seit ein paar Wochen in meinem DIY-Solar-Projekt verbaut und ausgiebig getestet. Was soll ich sagen: Die 66ah sind absolut real, kein Fake-Wert! Die Kapazität ist stabil, die Spannung von 3.7V bleibt auch unter Last super konstant und das Teil wird beim Laden kaum handwarm. Man merkt einfach sofort, dass die Verarbeitungsqualität stimmt und das PCB-Schutzboard ordentlich mitgedacht wurde. Für den Preis kriegt man hier in Deutschland aktuell kaum was Besseres. Versand war auch fix, Verpackung war bombensicher – so muss das laufen! Wer verlässliche Power sucht, kann hier echt bedenkenlos zugreifen. Von mir gibt's eine klare Kaufempfehlung und verdiente 5 Sterne. Daumen hoch!

As a veteran engineer in portable audio and smart hardware R&D, I demand the absolute best in battery electrical performance. We sourced this 103048 3.7V 1500mAh Li-polymer battery for a BT speaker project, and its real-world performance has completely blown us away.
