Der ProTek RC 3S 90C 1400mAh Si-Graphene+ HV LiPo Akku wurde speziell für Anwendungen entwickelt, bei denen wenig Platz und geringes Gewicht entscheidend sind – ideal für Scaler, FPV-Racing-Drohnen, Flite Test Flugzeuge, Competition-Crawler und Scale-Trucks mit Innenausstattung.
Mit kompakten Abmessungen von nur 70 × 34 × 22,5 mm und einem Gewicht von nur 115 g ist dieser Akku etwa 15 g leichter als ein vergleichbarer Standard-3S-1400mAh-LiPo – und liefert dabei mehr Leistung und Kapazität! Bei Ladung mit LiHV-Spezifikationen erreicht er 13,05 V statt der üblichen 12,6 V, was für konstantere Spannung und gleichmäßige Leistungsabgabe über den gesamten Entladevorgang sorgt.
Im Vergleich zu herkömmlichen LiPo- und LiHV-Zellen bieten Silicon-Graphene-Zellen:
Geringeren Innenwiderstand
Effizienteren Energiefluss
Weniger Hitzeentwicklung
Längere Laufzeiten und Lebensdauer
Höhere Spannung während der gesamten Entladung
Mehr Kapazität pro Gramm Gewicht
Labortests zeigen: Bei 1C Ladung verdoppelt sich die Lebensdauer – sogar höhere Laderaten sind mit geringerem Risiko für Zellenschäden möglich. Die flachere Entladekurve sorgt dafür, dass die Spannung auch am Ende des Zyklus hoch bleibt.
Nur 115 g – ca. 15 g leichter als Standard-3S-1400mAh-LiPos
13,05 V bei HV-Ladung, 11,4 V Nennspannung
Kompakt: 70 × 34 × 22,5 mm
90C Entladerate für maximale Leistungsausgabe
2C max. Ladestrom, 1C empfohlen für maximale Lebensdauer
Ideal für FPV Racing, Scaler, Crawler, Flugmodelle u. v. m.
Mehr Kapazität pro Gramm als herkömmliche LiPos
Verbesserte Spannungskurve & konstante Performance
