![]() SOOOO it all depends if you want to keep you batteries at 100% or at 85(ish)%. But I prefer having the ElectroDacus control all input and output for the pack. I could set the output voltage of the ac to dc converter at a point below that of the fully charged value of the LIFEpo4 pack, and "float" them at let's say 3.3 volts per cell. ![]() Also, the wiring in a standard 7 pin trailer connector is a bit too small to handle anything coming from the alternator to the trailer over 18 amps. I have 240ah and can expand that if needed. The Alternator of the tow vehicle will also be providing current into the dc to dc converter.ĭownsides to this setup: You are always drawing off the batteries and do not get the full benefit of the 50 (advertised) amps of the ac to dc converter as the dc to dc converter is limited at 18 amps (verified). When the cell voltage reaches the high voltage setting the ElectroDacus shuts off the Victron DC to DC converter which disconnects all charging load. The BMS is an ElectroDacus and I run the Ac to Dc charger into a Victron 12 12-18 DC to DC converter. Your Mileage May Vary, but this is what I did:Īfter many discussions with ElectroDacus I used my ac to dc 50 amp charger to charge my LIFEpo4 pack. The Converter Status Remote Pendant will indicate the Charger/Converter status and allows for manual Charge Wizard mode selection The Converter Status Remote Pendant plugs into the Accessory Port that is built-in on all PD9200 Series converters. STORAGE Mode 13.2 Volts – Maintains charge with minimal gassing or water loss.ĮQUALIZATION Mode 14.4 Volts – Every 21 hours for a period of 15 minutes NORMAL Mode 13.6 Volts – Safely completes the charge. The Charge Wizard constantly monitors battery voltage and battery usage then selects one of the following four operating modes to properly charge and maintain the battery.īOOST Mode 14.4 Volts – Rapidly brings the RV battery up to 90% of full charge. BattleBorn suggested it for my use case rather than replace the converter. I added a Charge Wizard pendant ($12 on Amazon) which manually puts it in boost mode at 14.4 for a few hours.
