What battery charger do I need?

Looking to upgrade a RV to lithium. I have 4 120AH 12V LiCube LiFePo4 Modular batteries (http://filimatic.si/wp-content/uploads/2014/09/LICUBE_traktion_GB.pdf). What Victron Multiplus charger/inverter would work with these 4 batteries?

I'd recommend the Multiplus 12/3000/120-50/120v. We've sold quite a few of these to customers with very similar lithium house banks (Battle Born or Victron, usually), and they have all been extremely happy with the performance.

I'd definitely recommend a BMV-712 with this setup as well... after you've spent this much on batteries and a Multiplus, it's well worth the extra couple hundred dollars to be able to keep a very close eye on your battery state.

You have a lot of options in the Victron line. Things you need to answer for yourself first:

1) what grid/shore/generator sources will you have

2) do you already have a transfer switch, and what is your AC topology

3) how much power would you like

4) how much space and weight capacity do you have

5) how much money do you have

Have a look through the MultiPlus and Quattro lineup for some of the most common models people use on RVs (myself included).

This forum is not a great place for system design discussion, being more question-oriented, but hopefully this will get you started.
