Variazione della resistenza interna di una famiglia di LiPo

Il mercato offre una larga varietà di brand che commerciano batterie LiPo. Il numero di brand non riflette un equivalente numero di produttori di celle LiPo, ovvero la produzione delle celle lipo viene eseguita da un ridotto numero di fabbriche. Sicuramente nelle linee di produzione esisterà qualche controllo di qualità che permetterà di separare le celle in funzione delle caratteristiche possedute. Forse i brand che propongono celle lipo a prezzi esosi offriranno solo celle di prima qualità. Forse.

Io non intendo svenarmi nell'acquisto di batterie lipo anche perchè per la tipologia di modelli in mio possesso non mi occorrono elevate performances. Dopo aver provato diverse famiglie di Lipo mi sono stabilizzato con le NanoTech a bassa scarica (25-50c) vendute da HobbyKing.

Complice l'acquisto del recente caricabatteria ISDT Q6 Plus, ho deciso di monitorare l'andamento della resistenza interna di 12 batterie Nanotech in mio possesso. Sicuramente è un pò noioso appuntarsi questi valori alla fine di ogni ricarica ma per avere dei risultati un poco attendibili devo necessariamente seguire un gruppo di batterie. Il gruppo è costituito da 8 batterie da 4500mA 6s e da 4 batterie da 3300mA 6s entrambi da 25-50c. Il primo gruppo è etichettato da 1 a 8 ed il secondo da 9 a 12. In realtà nell'archivio ci sono altre 2 batterie (x2 ed x3) ma sono difettose e non fanno testo.

L'archivio sarà aggiornato fino a quando avrò la pazienza di continuare a rilevare i dati 😀

Come visibile dalla foto, inizialmente ho usato una basetta adattatrice per i connettori di bilanciamento. A causa della scarsa qualità della basetta, dopo un certo periodo, ho cominciato a ricevere notifiche di errore da parte del caricabatteria. Alla fine ho deciso di eliminare le 4 basette adattatrici e di connettere direttamente le LiPo ai caricabatteria. In questo modo la misura della resistenza interna delle celle si è abbassata falsando la media totale delle letture. Nell'archivio si nota infatti un miglioramento dei valori che non si spiegherebbe altrimenti... Avrei dovuto eliminare i rilevamenti precedenti ma non ho voluto farlo. 🙂
