28 Lithium Cell Install

I have a 2006 e4 GEM (all stock), and I’m looking to do a lithium conversion. By chance I just inherited a packaged 16 cell, and 12 cell lithium block that I will not be able to remove cells from so I’m kind of stuck in the 84-117V range, when I put them in series. I’m actually a lithium battery engineer so I’m familiar with the batteries I just need some help integrating them.

Looking through the forums it looks like the first thing I need to do is the voltage spoof to get rid of the overvoltage error that I’m seeing when I turn on the vehicle. So from this situation I have a couple questions.

1.) How do I do the spoof? Is this something I can do myself or do I need to purchase something for this? I think @Inwo may have some info on this?
2.) Is 117V to high for some of the components, or has this been done before with the stock components? If this is too high I can just run a certain voltage range until I get batteries more appropriate for the components.

Thanks for any help!
