Witam kupiłem wasza ładowarkę 20a ładuje ja akumulator lifepo4 i nie wiem dlaczego ładuje tylko prądem 7 amper
Witam,
Ta ładowarka 20A nie pracuje cały czas pełnym prądem 20A.
Przy akumulatorach LiFePO4 prąd automatycznie spada, gdy akumulator jest prawie naładowany. Dodatkowo prąd może być ograniczony do okolic 7A z powodu poziomu naładowania baterii, ochrony temperaturowej lub zbyt cienkich przewodów.
Pełne 20A osiąga tylko przy mocno rozładowanej baterii i poprawnym podłączeniu.
