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!

I bought these 805050 3.7V 2500mAh lithium polymer batteries to replace the old cells in my Bluetooth speakers, and they work brilliantly. Fit is absolutely perfect, no trimming needed at all. The voltage and capacity are spot on, my speakers now hold charge for much longer than before. Power output is stable, sound quality isn’t affected one bit. They’re well-made and feel really durable. Delivery arrived quickly, items were well packed with no damage. Great value for money compared to local stores. I’ve been using them daily for weeks with zero issues. Would absolutely recommend these batteries to anyone needing replacements for wireless speakers. I’ll be coming back to buy more soon!
