John E Davies Posted March 11, 2021 Share Posted March 11, 2021 (edited) Has anybody messed around with this? I am trying to get my unknown loads completely eliminated or reduced. I want to be able to run ONLY the Natures Head toilet fan off the lithium batteries, to keep the bacteria happy. I don’t want to keep plugged into shore power with the converter running because that is not great for the battery health, and it is stored indoors, so no solar. For example... these are the current readings on my VictronConnect app: Phantom (no known loads): 0.12 amps Toilet fan ON: 0.16 amps (+0.04) Propane detector ON: 0.21 amps (+0.05) - Solution: added a manual power switch. Stereo ON: 0.36. amps (+0.15) - Solution: turned off circuit breaker in rear overhead closet. I found these possible extra reductions: Redarc DC to DC charger: 0.01 amps - Solution: turn off its circuit breaker Blue Sea overhead circuit breaker LED lighting 0.01 amps - requires opening the unit and cutting wires. Not practical. Any other possibilities? I have pulled fuses and tried all sorts of things, I still cannot figure out where that extra power is going. The Victron BMV-712 Smart Battery Monitor uses just 0.001 amp. I am getting there, I was at 0.36A and am now at 0.15A with just the toilet fan turned on. Maybe I should call that good...? Am I anal? No need to answer that one.... I suppose I should be out camping. EDIT: 0.15 amps x 24 hrs x 30 days = 108 amp hrs per month. So it would flatten my 200 AH bank in two months. Sure I can keep recharging it, but I would rather not just keep adding cycles. Maybe I will rewire the NH circuit, as suggested by a member, and power that “keep alive” wire with the master switch turned off.
