I own a Centaur 12-40 installed in my sailing boat, charging two banks of batteries. Start bank and service bank. Service bank includes two 90 Amp Victron Gel batteries. I intend now to change this ones for two 100 A LiFePO4 (lithium). This Lithium batteries demand Charge Voltage 14,6 volts and Float Charge 13,5 volts. The charge voltage for LA (Especially flooded lead acid batteries) indicated in the Manual is accurately 14,5 Absorption Charge, and 13,5 on Float, so exact voltages for Lithium. Is it possible to charge LiFePO4 (Lithium) batteries with this charger ? Thanks for any info.
Sorry Manuel, we cannot answer your question clearly. Your Centaur is designed for charging lead-acid batteries. According to the manual, it delivers 14.5 or 13.5 volts (lead-acid setting). This may fit, but what you also have to take into account is that the Centaur's lead-acid charging characteristic is temperature compensated. It is assumed that battery and charger are in an environment with "normal room temperature" (20-25°C). An integrated temperature sensing reduces the charging voltage by -12mV/°C for a 12 V battery. Example: At a temperature difference of + 15 K, the charging voltage would be 0.18 V lower, i.e. only at approx. 14.3 V. Lithium batteries are charged with a constant voltage without temperature compensation. We cannot tell you whether the BMS of your lithium battery can handle the variable charging voltages of your Centaur.
