Hello,
I have 2 lithium 100 amp batteries that I want to add to my 2003 Itasca Spirit E450 class C rv. They will not fit under the stairs of where the current coach/house deep cycle batteries are and I will need to install them possibly under the couch in the RV so this will help keep them from potential freezing. Since this is the case, I was thinking of keeping the coach batteries as they are becuase I can use them to run the DC components such as lights, pumps etc. I want to add 2 100 amp lithium batteries with a renogy DC to DC charger with MPPT and a renogy 2000 watt inverter. I will later buy portable solar panels to use as needed. My thoughts were to wire the dc to dc charger directly to the starter battery with a kill switch so I only use it as needed when the engine is running. I will add 2 120 volt outlets in the RV that wil be dedicated to this inverter so this will be independant from the RV circuits. Having this as a seperate circuit, I can power the inverter on and off as needed and not have to worry about draining the lithium batteries. I know that I will need to use proper guage wire and have the correct fuses and breakers as needed. Honestly, I am hesitant to disrupt the fully functioning coach/house battery setup that in a pinch can also be used to jump start the vehicle starter battery if I ever need to. I guess my main question is, has anyone else ever done anything like this? And if I proceed as planned, is there anything I should worry about? it would be great to see pictures.
Thanks all,
Arnold
