Positive bus bar on Imagine 2670MK

[Kev2504]

I am in the process of moving my 2 100AH LiTime batteries to under the bed. Under the front frame there is what I think is the bus bar. Can anyone confirm if this is just a bus bar, and not a circuit breaker type?

That is not a buss bar. That's an auto circuit breaker. You'll want to leave all that wiring in place. I suggest also leaving the wiring to the existing batteries in place and capping off the ends so it's there if you decide to sell the RV down the road and want to keep your lithium batteries. That way you can throw on a lead-acid and the next person can decide what they want to do. Just my $.02.

I actually used those wires to power "posts" that I can use for clamp connectors to power my air compressor, 12 v box fan outside, stand alone water pump, etc. They come in handy.

I had that feeling that's what it is. It would be nice if GD had it weather protected. I'll just cap it off like you suggested. I will run a wire from the existing disconnect to my new bus bar to charge my batteries. I am installing a 2000 watt inverter so will have a pos and a neg bus bar with a 250A fuse and disconnect. So that is a great idea. here is a sketch of my inverter wiring. Thanks

Looks good. The only question I would have is are those buss bars the OEM bars, or are you upgrading them? If OEM, I would leave them out of the picture and connect the lugs directly to your cutoff switch (+) and to the shunt (-). Those stock bars are pretty crappy. It's okay to stack a couple of lugs on a terminal, so unless you add more devices down the road, you would be okay. If you find you need to add another lug, then install good buss bars. Again, my $.02.

No they are new ones rated for 275 amps. All my new cables will be 2/0.
thanks for the input. it helps

I did this a few years ago following Jared Gillis videos and documents and asking questions on here about details. I put the 3000W inverter in the pass through, batteries under the bed, and had a spice box under my "closet" where the power comes in. I had to split the 50 in two so half the rig runs off the invertor and I can only run the other half of the breaker box when plugged in. I can run all outlets, microwave, & fridge. I cannot run the ac, outdoor kitchen fridge, or electric fireplace. We boondock a decent amount and dreaded running a generator to make coffee. If we need the ac then it has to run.

There are invertors that can do both legs now but honestly I would need more battery power to even think of running the ac for any amount of time. We can go about two full days with what we have depending on how much the furnace blower runs and we run the fridge off propane when boon docked. This include using coffee maker, microwave, hairdryer along with tv and such.

I have a power point with notes in it and photos but it doesn't upload ppt files here.
