How to set the charging voltage value of the charger?
The DC-DC battery charger adopts the design of the DIP switch and it provides 6 charging voltage settings through five gears. These six charging voltages meet the requirements of lithium batteries and lead-acid batteries in order to provide more charging options. SW5 switch is the selection switch for switching between lead-acid batteries and lithium batteries.

Lo consiglio, qualit prezzo eccezionale ricarica il 15% delle batterie dei servizi in meno di 50 km.
Ho collegato il tutto senza il minimo sforzo, libretto delle istruzioni dettagliato, ho perso tempo solo per posizionare il cavo dalla chiave del quadro al led.
Molti amici camperisti mi hanno chiesto il senso di installare un prodotto di questo tipo quando c’ gi il classico sistema “parallelatore”, beh la risposta semplice: vi far funzionare meglio e durare di pi la batteria servizi ricaricandola sempre nel modo pi corretto a seconda della sua chimica (comprese quelle al litio). L’installazione dipende ovviamente dalla configurazione del mezzo ma dal punto di vista elettrico molto semplice e ben spiegata nel manuale incluso (attenzione ad usare sempre cavi di sezione adeguata, anche quelli comunque indicati nel manuale).
