240v hook up

[Pdrew_t5.1]

Hi, I'm in the process of updating my leisure battery setup. I'm currently using a AGM battery with a simple split charge relay. I'm in need of replacing my battery but also wanting to replace the split charge system with a battery to battery charger I'm also wanting to introduce 240v to keep the leisure battery charging while using the 12v lights, fridge etc. what's the simplest way of doing so? Are there any DC to DC chargers with 240v input?
Thanks for any help

there are . . . . but they are super expensive (comparatively speaking)

best way forward is:

new lithium LB, - Lithium LifePo4 12v Batteries - Time For An Upgrade?

new dc-dc charger, - [Guide] DC-DC Charger (for leisure battery) -- How I Done It --

then add in a battery charger, - Battery Chargers - How I Did It -


..



then you can look at adding in some solar if you wanted.
