2018 roadtrek Zion srt batteries

[bommo]

Just purchased a 2018 Zion srt. Spent $600 to have it inspected. The inspector missed a lot of important things. He didnt know it had a macerator, which it does and the pump is dead so I had to pay $600 to have it replaced. HE also said on his report that the rig had lithium batteries. Batteries wouldnt last long so I looked under the rig and found he lied they are AGM batteries. Has anyone upgraded AGM to Lithium? The process I find on line range form $1600 to $7000. Anyone have real life price estimates?

Do a search, this has been discussed to death and the info is in here. The inspector, if he is a real inspector, should be reported to the certification outfit he is thru. That is unacceptable.

I found replacement batteries on eBay there is a site in MS that will replace them with (2) 240 ah for $3300, which is a lot less that the ~$7000 I was quoted form original vendor. Link below If interested. The price includes installation but you have to go to Mississippi, or they can ship to you

I would go this route vs the OEM KS2 batteries, they are garbage. I just did a conversion, but moved them inside. Accessing those boxes under the van is a pain.
640 AH for $1400. Plus prob removed 300 lbs worth of boxes, cable and the aux AGM.
Also added nice shunt for easy monitoring.
