Battery drain
I have 2 interstate batteries SRM 24 deep cycle batteries. Have the VictronConnect bmv712 battery monitor. Had to leave our camper sit for 4 days without charging and drew batteries down to 11.6volts...

Also I have the stock WFCO 9865 in my rv but just ordered a Boondocker 1275 4 stage that was recommended. I was trying to bring the interstate batteries back to life with an external 3 stage 15 amp charger but it didn’t seem to help. With the current WFCO onboard converter, I never saw the volts get up to 14+ when charging a really low battery while looking at my VictronConnect monitor.
I just replaced the WFCO 8955 with a Boondocker 55 amp over the weekend. Now the two GC2 batteries are being charged properly. I never saw the WFCO go over 13.7 volts, now the Boondocker ramps up to 14.7 volts, drops back to 13.8 volts to complete the charge, and then to 13.2 volts to maintain.
