Lithium battery/ dc to dc upgrade

[slybacon67]

Hi all. I would like to upgrade my battery and charging system. At present I have a 100 ah Efb leisure battery charging via a VSR and standard mains hook up (13.8v) see pics and also I have a dokio 160w plug and play solar panel which has its own controller. I would like to fit under the drivers seat a lithium 100ah lifepo4 battery ( which may have to go on its side) alongside a victron 12/12/30 dc to dc charger (remove the vsr) but leave in situ the solar system and my mains hook up system. Will this work or should I swap out everything I understand mains hookup might not charge battery perfect and I would poss upgrade eventually. I like the victron charger as it utilises common ground and saves me running an ignition wire but I am open to suggestions and ideas. I have included a few pics.

You have the advantage though your EHU charger is its own unit not built in. So you could swap that out for something like a Victron mains charger that has a lithium charge profile without changing too much.

What controller does the solar panel use?

Thats the link to the solar charger i bought earlier in year , it states it can charge lifepo4 batteries so i assume its ok, was trying to save myself some work and cash by utilising the hookup charger i have fitted but not impossible to fit another one. which one would you recommend.
