AGM/LITHIUM question

[JT3296]

Hey guys, I'm new to the group and I come barring questions!!!.. important questions tho lol

 

I have a 2019 Ford Edge with stock radio using a D4S EZ SNI35-2V 2ch. loc converter and I just installed:

 

-Excessive Amperage 400a alternator (charges around 14.7- 15ish at idle) I'm going to wire a little volt meter in to monitor it) 

 

-Big 3 installed

 

-1/0 wiring 

 

-2 runs of 1/0 gauge w/ double anl fuse holders/600a anl fuse back to the amp (sundown salt-6) 

 

-ROCK LIGHTS (for both outside/inside of car) (Not installed yet)

 

Resting volts for batteries:

-AGM/12.64

-Liths./13.13(all 3 individually read same)

 

- XS Power D4800 (2,000-3,000w) AGM battery under the hood 

 

-3 D4S LTO-6.0 12V Lithium batteries (w/buss bars) (6,000-10,000w) in the back (NOT installed yet) 

But ive been reading around online and I'm seeing both yay and nay with running both AGM and lithium. I'm seeing stuff about resting volts for both, isolators (and when to use them/car on&off) run a set of wire straight off alt. to the lithiums and then I've alsol read not to run those wires. I seen something about wiring the batteries in parallel (w/isolator (&also) w/o isolator) or wire in series, use a DC-DC converter vs isolator...

 

So my question is, what do I do here and how do I do it lol. I know lithiums charge faster and hold a higher rest volt so I don't want to do a straight run from the alt. Or do I get isolator/DC-DC converter and wire it to the power wire going back or wire straight to the battery? 

 

Can that combination of batteries and setup even be safely possible? Or do I completely do away with them and get a different type of battery? 

Thanks for your suggestions and helps!

Some lithium chemistry's cant be ran with agm or lead acid batteries.

The D4S LTO 6.0 can be though, I have a few different people using them with mixed setups using XS Power D3400s as starting batteries and the LTO in the back by the amps with no problems, no isolators, and no other converters like people are rambling about.

Now if it was a chemistry that cant be ran with agms, then you would need some sort of isolator, but then its still stupid because you just delete the front battery and run everything off the lithium and be done with it. Which is why you see people build dumb wooden boxes the size of a battery and call it a battery delete, all you really need though is just a distribution hub under the hood to connect the factory 12v electronics too. Simple buss bars do that just fine.
